STTRS DOCUMENTATION Document Number 80-330501HBKM Issue A - Draft Page 14 of 500 2. SAFETY CONSIDERATIONS 2.1. Earthing of Equipment Equipment supplied from the mains must be connected to grounded outlets and earthed in conformity with appropriate local, national and international electricity supply and safety regulations. 2.2. Electric Shock Hazard The risk of electrical shocks due to faulty mains driven power supplies whilst potentially ever present in any electrical equipment, would be minimised by adherence to good installation practice and thorough testing at the following stages:
Original assembly. Commissioning. Regular intervals, thereafter. a) b) c) All test equipment must be in good working order prior to its use. High current power supplies can be dangerous because of the possibility of substantial arcing. Always switch off during disconnection and reconnection. 2.3. RF Radiation Hazard RF radiation, (especially at UHF frequencies) arising from transmitter outputs connected to AFLs equipment, must be considered a safety hazard. This condition might only occur in the event of cable disconnection, or because a spare output has been left un-terminated. Either of these conditions would impair the systems efficiency. No investigation should be carried out until all RF power sources have been removed. This would always be a wise precaution, despite the severe mismatch between the impedance of an N type connector at 50, and that of free space at 377, which would severely mitigate against the efficient radiation of RF power. Radio frequency burns could also be a hazard, if any RF power carrying components were to be carelessly touched!
Antenna positions should be chosen to comply with requirements (both local & statutory) regarding exposure of personnel to RF radiation. When connected to an antenna, the unit is capable of producing RF field strengths, which may exceed guideline safe values especially if used with antennas having appreciable gain. In this regard the use of directional antennas with backscreens and a strict site rule that personnel must remain behind the screen while the RF power is on, is strongly recommended. Where the equipment is used near power lines or in association with temporary masts not having lightning protection, the use of a safety earth connected to the case-earthing bolt is strongly advised. 2.4. Lifting and other Health and Safety Recommendations Certain items of AFL equipment are heavy and care should be taken when lifting them by hand. Ensure that a suitable number of personnel, appropriate lifting apparatus and appropriate personal protective equipment is used especially when installing Cell Enhancers above ground e.g. on a mast or pole. STTRS DOCUMENTATION Document Number 80-330501HBKM Issue A - Draft Page 15 of 500 2.5. Chemical Hazard Beryllium Oxide, also known as Beryllium Monoxide, or Thermalox, is sometimes used in devices within equipment produced by Aerial Facilities Ltd. Beryllium oxide dust can be toxic if inhaled, leading to chronic respiratory problems. It is harmless if ingested or by contact. Products that contain beryllium are dummy loads (load terminations) and some power amplifiers. These products can be identified by a yellow and black skull and crossbones danger symbol (shown above). They are marked as hazardous in line with international regulations, but pose no threat under normal circumstances. Only if a component containing beryllium oxide has suffered catastrophic failure, or exploded, will there be any danger of the formation of dust. Any dust that has been created will be contained within the equipment module as long as the module remains sealed. For this reason, any module carrying the yellow and black danger sign should not be opened. If the equipment is suspected of failure, or is at the end of its life-cycle, it must be returned to Aerial Facilities Ltd for disposal. To return such equipment, please contact the Quality Department, who will give you a Returned Materials Authorisation (RMA) number. Please quote this number on the packing documents, and on all correspondence relating to the shipment. PolyTetraFluoroEthylene, (P.T.F.E.) and P.T.F.E. Composite Materials Many modules/components in AFL equipment contain P.T.F.E. as part of the RF insulation barrier. This material should never be heated to the point where smoke or fumes are evolved. Any person feeling drowsy after coming into contact with P.T.F.E. especially dust or fumes should seek medical attention. 2.6. Laser Safety General good working practices adapted from EN60825-2: 2004/ EC 60825-2:2004 Do not stare with unprotected eyes or with any unapproved optical device at the fibre ends or connector faces or point them at other people, Use only approved filtered or attenuating viewing aids. Any single or multiple fibre end or ends found not to be terminated (for example, matched, spliced) shall be individually or collectively covered when not being worked on. They shall not be readily visible and sharp ends shall not be exposed. When using test cords, the optical power source shall be the last connected and the first disconnected; use only approved methods for cleaning and preparing optical fibres and optical connectors. Always keep optical connectors covered to avoid physical damage and do not allow any dirt/foreign material ingress on the optical connector bulkheads. The optical fibre jumper cable maximum bend radius is 3cm; any smaller radii may result in optical cable breakage or excessive transmission losses. Caution: The FO units are NOT weather proof. 2.7.

Four Way Splitter/Combiner (05-003302) The Splitter/Combiner used is a device for accurately matching two or more RF signals to single or multiple ports, whilst maintaining an accurate 50 load to all inputs/outputs and ensuring that the VSWR and insertion losses are kept to a minimum. Any unused ports should be terminated with an appropriate 50 load.

Therefore, provision is made within the unit for the setting of attenuation in each path, to reduce the gain. Switched Attenuator 10-000701 provides attenuation from 0 to 30dB in 2 dB steps The attenuation is simply set using the four miniature toggle switches on the top of each unit. Each switch is clearly marked with the attenuation it provides, and the total attenuation in line is the sum of the values switched in. They are designed to maintain an accurate 50 impedance over their operating frequency at both input and output. 10-000701 Specification PARAMETER SPECIFICATION Attenuation Values 0-30dB Attenuation Steps 2, 4, 8 and 16dB Power Handling 0.25 Watt Attenuation Accuracy 1.0 dB Frequency Range DC to 1GHz Impedance 50 Connectors SMA VSWR 1.3:1 Weight 0.2kg Temperature range operation storage

Dummy Load (80-007401) When a combiner system is used to split or combine RF signals, in many cases it is most cost effective to use a standard stock item 4, 6 or 8 port device where, in fact, only a 3 or 6 port device is needed. In this case the Four Way Splitters (05-003302) each have two of their ports terminated with Dummy Load (80-007401) in order to preserve the correct impedance of the devices over the specified frequency range. This also has the advantage of allowing future expansion capability should extra channels or other functions become necessary. Dummy Load (80-007401) Specification Parameter Specification VSWR

Per Assembly 1 4.2.4.1. Single Mode Optical Splitter/Coupler (98-100001) Single Mode Optical Splitter/Couplers are used whenever it is necessary to split or combine outputs from optical transmitters or inputs to receivers. Operators should be aware that a small insertion loss
(typically 3-4dB) is common with these type of couplers. Single Mode Optical Splitter/Coupler (98-100001) It is an O.E.M unit featuring almost negligible insertion loss to the F/O signal. Extreme caution should be exercised when handling these devices. Special attention should be shown to the connectors; repair of a broken Splitter/Coupler is not possible; replacement is the only option. In the two Fibre Optic Splitters (55-165507) in 800MHz KCRS Master Site (80-330651), Single Mode Optical Splitter/Coupler (98-100001) is used to split the optical signal from the FO TX modules in F/O Link Subsystem (98-700001) into two equal paths.

Bandpass Filter (02-007206) in order to optimise The bandpass filters are multi-section designs with a bandwidth dependent upon the passband frequencies, (both tuned to customer requirements). The response shape is basically Chebyshev with a passband design ripple of 0.1dB. The filters are of slot coupled, folded combline design, and are carefully aligned during manufacture loss, VSWR and intermodulation characteristics of the unit. The tuned elements are silver-plated to reduce surface ohmic losses and maintain a good VSWR figure and 50 load at the input and output ports. Being passive devices, the bandpass filters should have an extremely long operational life and require no maintenance. Should a filter be suspect, it is usually most time efficient to replace the module rather than attempt repair or re-tuning. No adjustments should be attempted without full network sweep analysis facilities to monitor both insertion loss and VSWR simultaneously. 02-007206 Specification insertion the PARAMETER SPECIFICATION Response type Chebyshev Frequency range 800 - 950MHz *

The AGC with logarithmic detector (17-001117) is fitted in the uplink path and the AGC with linear detector (17-001109) is fitted in the downlink path The AFL Automatic Gain Control system consists of two units, a detector/amplifier and an attenuator. The detector/amplifier unit is inserted in the RF path on the output of the power amplifier, and the attenuator is situated in the RF path between the 1st and 2nd stages of amplification. 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the downlink The attenuator comprises a 50 P.I.N diode, voltage-variable attenuator with a range of 3 to 30dB. The attenuation is controlled by a DC voltage which is derived from the associated detector controller board. Normally the attenuator is at minimum attenuation. The detector/amplifier unit monitors the RF level being delivered by the power amplifier, and when a certain threshold is reached it begins to increase the value of the attenuator to limit the RF output to the (factory set) threshold. Therefore overloading of the power amplifier is avoided. The factory set threshold is 1dB below the Enhancer 1dB compression point. Some adjustment of this AGC threshold level is possible, a 10dB range is mostly achieved. It is not recommended under any circumstances to adjust the AGC threshold to a level greater than the 1dB compression point as system degradation will occur. STTRS DOCUMENTATION Document Number 80-330501HBKM Issue A - Draft Page 37 of 500 The detector comprises of a 50 transmission line with a resistive tap which samples a small portion of the mainline power. The sampled signal is amplified and fed to a conventional half wave diode rectifier, the output of which is a DC voltage proportional to the RF input signal. This DC voltage is passed via an inverting DC amplifier with integrating characteristics, to the output, which drives the attenuation control line of the corresponding AGC attenuator. This unit is fitted at some earlier point in the RF circuit. For small signals, below AGC onset, the output control line will be close to 12V and the AGC attenuator will have minimum attenuation. As the signal level increases the control line voltage will fall, increasing the attenuator value and keeping the system output level at a constant value.

Bandpass Filter (02-007206) in order to optimise The bandpass filters are multi-section designs with a bandwidth dependent upon the passband frequencies, (both tuned to customer requirements). The response shape is basically Chebyshev with a passband design ripple of 0.1dB. The filters are of slot coupled, folded combline design, and are carefully aligned during manufacture loss, VSWR and intermodulation characteristics of the unit. The tuned elements are silver-plated to reduce surface ohmic losses and maintain a good VSWR figure and 50 load at the input and output ports. Being passive devices, the bandpass filters should have an extremely long operational life and require no maintenance. Should a filter be suspect, it is usually most time efficient to replace the module rather than attempt repair or re-tuning. No adjustments should be attempted without full network sweep analysis facilities to monitor both insertion loss and VSWR simultaneously. 02-007206 Specification insertion the PARAMETER SPECIFICATION Response type Chebyshev Frequency range 800 - 950MHz *

Bandpass Filter (02-007206) in order to optimise The bandpass filters are multi-section designs with a bandwidth dependent upon the passband frequencies, (both tuned to customer requirements). The response shape is basically Chebyshev with a passband design ripple of 0.1dB. The filters are of slot coupled, folded combline design, and are carefully aligned during manufacture loss, VSWR and intermodulation characteristics of the unit. The tuned elements are silver-plated to reduce surface ohmic losses and maintain a good VSWR figure and 50 load at the input and output ports. Being passive devices, the bandpass filters should have an extremely long operational life and require no maintenance. Should a filter be suspect, it is usually most time efficient to replace the module rather than attempt repair or re-tuning. No adjustments should be attempted without full network sweep analysis facilities to monitor both insertion loss and VSWR simultaneously. 02-007206 Specification insertion the PARAMETER SPECIFICATION Response type Chebyshev Frequency range 800 - 950MHz *

Switched Attenuator 0.25Watt, 0 - 30dB (10-000701) In many practical applications for Cell Enhancers etc., the gain in each path is found to be excessive. Therefore, provision is made within the unit for the setting of attenuation in each path, to reduce the gain. Switched Attenuator 10-000701 provides attenuation from 0 to 30dB in 2 dB steps The attenuation is simply set using the four miniature toggle switches on the top of each unit.

The AGC with logarithmic detector (17-001117) is fitted in the uplink path and the AGC with linear detector (17-001109) is fitted in the downlink path The AFL Automatic Gain Control system consists of two units, a detector/amplifier and an attenuator. The detector/amplifier unit is inserted in the RF path on the output of the power amplifier, and the attenuator is situated in the RF path between the 1st and 2nd stages of amplification. 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the downlink The attenuator comprises a 50 P.I.N diode, voltage-variable attenuator with a range of 3 to 30dB. The attenuation is controlled by a DC voltage which is derived from the associated detector controller board. Normally the attenuator is at minimum attenuation. The detector/amplifier unit monitors the RF level being delivered by the power amplifier, and when a certain threshold is reached it begins to increase the value of the attenuator to limit the RF output to the (factory set) threshold. Therefore overloading of the power amplifier is avoided. The factory set threshold is 1dB below the Enhancer 1dB compression point. Some adjustment of this AGC threshold level is possible, a 10dB range is mostly achieved. It is not recommended under any circumstances to adjust the AGC threshold to a level greater than the 1dB compression point as system degradation will occur. The detector comprises of a 50 transmission line with a resistive tap which samples a small portion of the mainline power. The sampled signal is amplified and fed to a conventional half wave diode rectifier, the output of which is a DC voltage proportional to the RF input signal. This DC voltage is passed via an inverting DC amplifier with integrating characteristics, to the output, which drives the attenuation control line of the corresponding AGC attenuator. This unit is fitted at some earlier point in the RF circuit. For small signals, below AGC onset, the output control line will be close to 12V and the AGC attenuator will have minimum attenuation. As the signal level increases the control line voltage will fall, increasing the attenuator value and keeping the system output level at a constant value.

Dual Diode Assembly (94-100004) The purpose of these dual diode assemblies is to allow two DC voltage sources to be combined, so that the main DC rail within the equipment can be sourced from either a mains driven PSU, or externally through an XLR connector or from dual mains driven PSUs. They are very heavy-duty diodes and they prevent any reverse current from flowing back to their source or the alternative supply rail. Combining diodes such as these will also be used if the equipment is to be powered from external back-up batteries.

Bandpass Filter (02-007206) in order to optimise The bandpass filters are multi-section designs with a bandwidth dependent upon the passband frequencies, (both tuned to customer requirements). The response shape is basically Chebyshev with a passband design ripple of 0.1dB. The filters are of slot coupled, folded combline design, and are carefully aligned during manufacture loss, VSWR and intermodulation characteristics of the unit. The tuned elements are silver-plated to reduce surface ohmic losses and maintain a good VSWR figure and 50 load at the input and output ports. Being passive devices, the bandpass filters should have an extremely long operational life and require no maintenance. Should a filter be suspect, it is usually most time efficient to replace the module rather than attempt repair or re-tuning. No adjustments should be attempted without full network sweep analysis facilities to monitor both insertion loss and VSWR simultaneously. 02-007206 Specification insertion the PARAMETER SPECIFICATION Response type Chebyshev Frequency range 800 - 950MHz *

Switched Attenuator 0.25Watt, 0 - 30dB (10-000701) In many practical applications for Cell Enhancers etc., the gain in each path is found to be excessive. Therefore, provision is made within the unit for the setting of attenuation in each path, to reduce the gain. Switched Attenuator 10-000701 provides attenuation from 0 to 30dB in 2 dB steps The attenuation is simply set using the four miniature toggle switches on the top of each unit.

The AGC with logarithmic detector (17-001117) is fitted in the uplink path and the AGC with linear detector (17-001109) is fitted in the downlink path The AFL Automatic Gain Control system consists of two units, a detector/amplifier and an attenuator. The detector/amplifier unit is inserted in the RF path on the output of the power amplifier, and the attenuator is situated in the RF path between the 1st and 2nd stages of amplification. 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the downlink The attenuator comprises a 50 P.I.N diode, voltage-variable attenuator with a range of 3 to 30dB. The attenuation is controlled by a DC voltage which is derived from the associated detector controller board. Normally the attenuator is at minimum attenuation. The detector/amplifier unit monitors the RF level being delivered by the power amplifier, and when a certain threshold is reached it begins to increase the value of the attenuator to limit the RF output to the (factory set) threshold. Therefore overloading of the power amplifier is avoided. The factory set threshold is 1dB below the Enhancer 1dB compression point. Some adjustment of this AGC threshold level is possible, a 10dB range is mostly achieved. It is not recommended under any circumstances to adjust the AGC threshold to a level greater than the 1dB compression point as system degradation will occur. The detector comprises of a 50 transmission line with a resistive tap which samples a small portion of the mainline power. The sampled signal is amplified and fed to a conventional half wave diode rectifier, the output of which is a DC voltage proportional to the RF input signal. This DC voltage is passed via an inverting DC amplifier with integrating characteristics, to the output, which drives the attenuation control line of the corresponding AGC attenuator. This unit is fitted at some earlier point in the RF circuit. For small signals, below AGC onset, the output control line will be close to 12V and the AGC attenuator will have minimum attenuation. As the signal level increases the control line voltage will fall, increasing the attenuator value and keeping the system output level at a constant value.

Bandpass Filter (02-007206) in order to optimise The bandpass filters are multi-section designs with a bandwidth dependent upon the passband frequencies, (both tuned to customer requirements). The response shape is basically Chebyshev with a passband design ripple of 0.1dB. The filters are of slot coupled, folded combline design, and are carefully aligned during manufacture loss, VSWR and intermodulation characteristics of the unit. The tuned elements are silver-plated to reduce surface ohmic losses and maintain a good VSWR figure and 50 load at the input and output ports. Being passive devices, the bandpass filters should have an extremely long operational life and require no maintenance. Should a filter be suspect, it is usually most time efficient to replace the module rather than attempt repair or re-tuning. No adjustments should be attempted without full network sweep analysis facilities to monitor both insertion loss and VSWR simultaneously. 02-007206 Specification insertion the PARAMETER SPECIFICATION Response type Chebyshev Frequency range 800 - 950MHz *

Switched Attenuator 0.25W, 0 - 15dB (10-000901) In many practical applications for Cell Enhancers etc., the gain in each path is found to be excessive. Therefore, provision is made within the unit for the setting of attenuation in each path, to reduce the gain. 10-000901 provides attenuation from 0 - 15dB in 2 dB steps The attenuation is simply set using the four miniature toggle switches on the top of each unit.

(AGC) system used in 800MHz Line Amplifier (Ext. Amp.) (55-165401); 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the downlink 800MHz Line Amplifier (Ext. Amp.) (55-165401) is fitted with two differing types of Automatic Gain Control (AGC) system, one linear, and one logarithmic. The AGC with logarithmic detector (17-
001117) is fitted in the uplink path and the AGC with linear detector (17-001109) is fitted in the downlink path The AFL Automatic Gain Control system consists of two units, a detector/amplifier and an attenuator. The detector/amplifier unit is inserted in the RF path on the output of the power amplifier, and the attenuator is situated in the RF path between the 1st and 2nd stages of amplification. 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the downlink The attenuator comprises a 50 P.I.N diode, voltage-variable attenuator with a range of 3 to 30dB. The attenuation is controlled by a DC voltage which is derived from the associated detector controller board. Normally the attenuator is at minimum attenuation. The detector/amplifier unit monitors the RF level being delivered by the power amplifier, and when a certain threshold is reached it begins to increase the value of the attenuator to limit the RF output to the (factory set) threshold. Therefore overloading of the power amplifier is avoided. The factory set threshold is 1dB below the Enhancer 1dB compression point. Some adjustment of this AGC threshold level is possible, a 10dB range is mostly achieved. It is not recommended under any circumstances to adjust the AGC threshold to a level greater than the 1dB compression point as system degradation will occur. STTRS DOCUMENTATION Document Number 80-330501HBKM Issue A - Draft Page 117 of 500 The detector comprises of a 50 transmission line with a resistive tap which samples a small portion of the mainline power. The sampled signal is amplified and fed to a conventional half wave diode rectifier, the output of which is a DC voltage proportional to the RF input signal. This DC voltage is passed via an inverting DC amplifier with integrating characteristics, to the output, which drives the attenuation control line of the corresponding AGC attenuator. This unit is fitted at some earlier point in the RF circuit. For small signals, below AGC onset, the output control line will be close to 12V and the AGC attenuator will have minimum attenuation. As the signal level increases the control line voltage will fall, increasing the attenuator value and keeping the system output level at a constant value.

It is equipped with a single dual pole change-over relay RL1, with completely isolated wiring, accessed via a 15 way in-line connector. The relay is provided with polarity protection diodes and diodes for suppressing the transients caused by "flywheel effect" which can destroy switching transistors or induce spikes on neighbouring circuits.

Dual Diode Assembly (94-100004) The purpose of these dual diode assemblies is to allow two DC voltage sources to be combined, so that the main DC rail within the equipment can be sourced from either a mains driven PSU, or externally through an XLR connector or from dual mains driven PSUs . They are very heavy-duty diodes and they prevent any reverse current from flowing back to their source or the alternative supply rail. Combining diodes such as these will also be used if the equipment is to be powered from external back-up batteries. 8.4.3.12.

The adjustment potentiometer will be found close to the DC output terminals. All the PSUs used in AFL Cell Enhancers are capable of operation from either 110 or 220V nominal AC supplies.

Bandpass Filter (02-007206) in order to optimise The bandpass filters are multi-section designs with a bandwidth dependent upon the passband frequencies, (both tuned to customer requirements). The response shape is basically Chebyshev with a passband design ripple of 0.1dB. The filters are of slot coupled, folded combline design, and are carefully aligned during manufacture loss, VSWR and intermodulation characteristics of the unit. The tuned elements are silver-plated to reduce surface ohmic losses and maintain a good VSWR figure and 50 load at the input and output ports. Being passive devices, the bandpass filters should have an extremely long operational life and require no maintenance. Should a filter be suspect, it is usually most time efficient to replace the module rather than attempt repair or re-tuning. No adjustments should be attempted without full network sweep analysis facilities to monitor both insertion loss and VSWR simultaneously. 02-007206 Specification insertion the PARAMETER SPECIFICATION Response type Chebyshev Frequency range 800 - 950MHz *

Switched Attenuator 0.25W, 0 - 15dB (10-000901) In many practical applications for Cell Enhancers etc., the gain in each path is found to be excessive. Therefore, provision is made within the unit for the setting of attenuation in each path, to reduce the gain. 10-000901 provides attenuation from 0 - 15dB in 2 dB steps The attenuation is simply set using the four miniature toggle switches on the top of each unit. Each switch is clearly marked with the attenuation it provides, and the total attenuation in line is the sum of the values switched in. They are designed to maintain an accurate 50 impedance over their operating frequency at both input and output. 10-000901 Specification PARAMETER Attenuation Values 0-15dB Attenuation Steps 1, 2, 4 and 8dB SPECIFICATION Power Handling 0.25 Watt Attenuation Accuracy 1.0 dB Frequency Range DC to 1GHz Impedance 50 Connectors SMA VSWR 1.3:1 Weight 0.2kg Temperature range operation -20C to +60C storage -40C to +70C 9.4.3.6.

Automatic Gain Control AGC Detector Assembly (Logarithmic) AGC Detector Assembly AGC Attenuator Assembly 17-001109 17-001117 17-001201 The sub components 17-001109, 17-001117 & 17-001201 are parts of the Automatic Gain Control
(AGC) system used in 800MHz Line Amplifier (Ext. Amp.) (55-165401); 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the downlink 800MHz Line Amplifier (Ext. Amp.) (55-165401) is fitted with two differing types of Automatic Gain Control (AGC) system, one linear, and one logarithmic. The AGC with logarithmic detector (17-
001117) is fitted in the uplink path and the AGC with linear detector (17-001109) is fitted in the downlink path The AFL Automatic Gain Control system consists of two units, a detector/amplifier and an attenuator. The detector/amplifier unit is inserted in the RF path on the output of the power amplifier, and the attenuator is situated in the RF path between the 1st and 2nd stages of amplification. 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the downlink The attenuator comprises a 50 P.I.N diode, voltage-variable attenuator with a range of 3 to 30dB. The attenuation is controlled by a DC voltage which is derived from the associated detector controller board. Normally the attenuator is at minimum attenuation. The detector/amplifier unit monitors the RF level being delivered by the power amplifier, and when a certain threshold is reached it begins to increase the value of the attenuator to limit the RF output to the (factory set) threshold. Therefore overloading of the power amplifier is avoided. The factory set threshold is 1dB below the Enhancer 1dB compression point. Some adjustment of this AGC threshold level is possible, a 10dB range is mostly achieved. It is not recommended under any circumstances to adjust the AGC threshold to a level greater than the 1dB compression point as system degradation will occur. STTRS DOCUMENTATION Document Number 80-330501HBKM Issue A - Draft Page 133 of 500 The detector comprises of a 50 transmission line with a resistive tap which samples a small portion of the mainline power. The sampled signal is amplified and fed to a conventional half wave diode rectifier, the output of which is a DC voltage proportional to the RF input signal. This DC voltage is passed via an inverting DC amplifier with integrating characteristics, to the output, which drives the attenuation control line of the corresponding AGC attenuator. This unit is fitted at some earlier point in the RF circuit. For small signals, below AGC onset, the output control line will be close to 12V and the AGC attenuator will have minimum attenuation. As the signal level increases the control line voltage will fall, increasing the attenuator value and keeping the system output level at a constant value.

It is equipped with a single dual pole change-over relay RL1, with completely isolated wiring, accessed via a 15 way in-line connector. The relay is provided with polarity protection diodes and diodes for suppressing the transients caused by "flywheel effect" which can destroy switching transistors or induce spikes on neighbouring circuits. Its common use is to amalgamate all the alarm signals into one, volts-free relay contact pair for the main alarm system. 80-008901 Specification PARAMETER SPECIFICATION Operating voltage 8 to 30V (floating earth) Alarm threshold Vcc - 1.20 volt +15%

Dual Diode Assembly (94-100004) The purpose of these dual diode assemblies is to allow two DC voltage sources to be combined, so that the main DC rail within the equipment can be sourced from either a mains driven PSU, or externally through an XLR connector or from dual mains driven PSUs . They are very heavy-duty diodes and they prevent any reverse current from flowing back to their source or the alternative supply rail. Combining diodes such as these will also be used if the equipment is to be powered from external back-up batteries. 9.4.3.12. DC/DC Converter 96-200047 96-200047 is an O.E.M. high power device with a wide input range and 12.5 amp @ 12V (150Watts) output capability used to derive a 12V fixed voltage power supply rail from a higher voltage supply, in this case 12V.

If a fault is suspected, then the output voltage from the power supply may be measured on its output terminals. This is typically set to 12.2V. The adjustment potentiometer will be found close to the DC output terminals. All the PSUs used in AFL Cell Enhancers are capable of operation from either 110 or 220V nominal AC supplies. The line voltage is sensed automatically, so no adjustment or link setting is needed by the operator. 96-300052 Specification AC Input Supply DC Output Supply 110 or 220V nominal Voltage 85 - 265V AC

Per Assembly 1 10.4.2.1. Single Mode Optical Splitter/Coupler (98-100001) Single Mode Optical Splitter/Couplers are used whenever it is necessary to split or combine outputs from optical transmitters or inputs to receivers. Operators should be aware that a small insertion loss
(typically 3-4dB) is common with these type of couplers. Single Mode Optical Splitter/Coupler (98-100001) It is an O.E.M unit featuring almost negligible insertion loss to the F/O signal. Extreme caution should be exercised when handling these devices. Special attention should be shown to the connectors; repair of a broken Splitter/Coupler is not possible; replacement is the only option. In the Fibre Optic Splitter (55-165507) in University Station Master Site 1 (80-330552-1), Single Mode Optical Splitter/Coupler (98-100001) is used to split the optical signal from the FO TX module in F/O Link Subsystem (98-700001) into two equal paths. 10.4.3. 800MHz FO Hub Amplifier + Filters (55-165601) Section Component Component Part Description Part 10.4.3.3. 10.4.3.4. 10.4.3.5. 10.4.3.6. 10.4.3.7. 10.4.3.8. 10.4.3.9. 10.4.3.10. 900MHZ 8POLE 25MHz+ B/W "SMA"

(AGC) system used in 800MHz FO Hub Amplifier + Filters (55-165601); 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the down link 800MHz FO Hub Amplifier + Filters (55-165601) is fitted with two differing types of Automatic Gain Control (AGC) system, one linear, and one logarithmic. The AGC with logarithmic detector (17-
001117) is fitted in the uplink path and the AGC with linear detector (17-001109) is fitted in the downlink path The AFL Automatic Gain Control system consists of two units, a detector/amplifier and an attenuator. The detector/amplifier unit is inserted in the RF path on the output of the power amplifier, and the attenuator is situated in the RF path between the 1st and 2nd stages of amplification. 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the down link The attenuator comprises a 50 P.I.N diode, voltage-variable attenuator with a range of 3 to 30dB. The attenuation is controlled by a DC voltage which is derived from the associated detector controller board. Normally the attenuator is at minimum attenuation. The detector/amplifier unit monitors the RF level being delivered by the power amplifier, and when a certain threshold is reached it begins to increase the value of the attenuator to limit the RF output to the (factory set) threshold. Therefore overloading of the power amplifier is avoided. The factory set threshold is 1dB below the Enhancer 1dB compression point. Some adjustment of this AGC threshold level is possible, a 10dB range is mostly achieved. It is not recommended under any circumstances to adjust the AGC threshold to a level greater than the 1dB compression point as system degradation will occur. The detector comprises of a 50 transmission line with a resistive tap which samples a small portion of the mainline power. The sampled signal is amplified and fed to a conventional half wave diode rectifier, the output of which is a DC voltage proportional to the RF input signal. This DC voltage is passed via an inverting DC amplifier with integrating characteristics, to the output, which drives the attenuation control line of the corresponding AGC attenuator. This unit is fitted at some earlier point in the RF circuit. For small signals, below AGC onset, the output control line will be close to 12V and the AGC attenuator will have minimum attenuation. As the signal level increases the control line voltage will fall, increasing the attenuator value and keeping the system output level at a constant value.

They are very heavy-duty diodes and they prevent any reverse current from flowing back to their source or the alternative supply rail.

Bandpass Filter (02-007206) in order to optimise The bandpass filters are multi-section designs with a bandwidth dependent upon the passband frequencies, (both tuned to customer requirements). The response shape is basically Chebyshev with a passband design ripple of 0.1dB. The filters are of slot coupled, folded combline design, and are carefully aligned during manufacture loss, VSWR and intermodulation characteristics of the unit. The tuned elements are silver-plated to reduce surface ohmic losses and maintain a good VSWR figure and 50 load at the input and output ports. Being passive devices, the bandpass filters should have an extremely long operational life and require no maintenance. Should a filter be suspect, it is usually most time efficient to replace the module rather than attempt repair or re-tuning. No adjustments should be attempted without full network sweep analysis facilities to monitor both insertion loss and VSWR simultaneously. 02-007206 Specification insertion the PARAMETER SPECIFICATION Response type Chebyshev Frequency range 800 - 950MHz *

The detector/amplifier unit is inserted in the RF path on the output of the power amplifier, and the attenuator is situated in the RF path between the 1st and 2nd stages of amplification. 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the downlink The attenuator comprises a 50 P.I.N diode, voltage-variable attenuator with a range of 3 to 30dB. The attenuation is controlled by a DC voltage which is derived from the associated detector controller board. Normally the attenuator is at minimum attenuation. The detector/amplifier unit monitors the RF level being delivered by the power amplifier, and when a certain threshold is reached it begins to increase the value of the attenuator to limit the RF output to the (factory set) threshold. Therefore overloading of the power amplifier is avoided. The factory set threshold is 1dB below the Enhancer 1dB compression point. Some adjustment of this AGC threshold level is possible, a 10dB range is mostly achieved. It is not recommended under any circumstances to adjust the AGC threshold to a level greater than the 1dB compression point as system degradation will occur. The detector comprises of a 50 transmission line with a resistive tap which samples a small portion of the mainline power. The sampled signal is amplified and fed to a conventional half wave diode rectifier, the output of which is a DC voltage proportional to the RF input signal. This DC voltage is passed via an inverting DC amplifier with integrating characteristics, to the output, which drives the attenuation control line of the corresponding AGC attenuator. This unit is fitted at some earlier point in the RF circuit. For small signals, below AGC onset, the output control line will be close to 12V and the AGC attenuator will have minimum attenuation. As the signal level increases the control line voltage will fall, increasing the attenuator value and keeping the system output level at a constant value.

Dual Diode Assembly (94-100004) The purpose of these dual diode assemblies is to allow two DC voltage sources to be combined, so that the main DC rail within the equipment can be sourced from either a mains driven PSU, or externally through an XLR connector or from dual mains driven PSUs. They are very heavy-duty diodes and they prevent any reverse current from flowing back to their source or the alternative supply rail. Combining diodes such as these will also be used if the equipment is to be powered from external back-up batteries. 10.4.4.14. DC/DC Converter 96-200047 96-200047 is an O.E.M. high power device with a wide input range and 12.5 amp @ 12V (150Watts) output capability used to derive a 12V fixed voltage power supply rail from a higher voltage supply, in this case 12V.

Per Assembly 1 11.4.1.1. Single Mode Optical Splitter/Coupler (98-100001) Single Mode Optical Splitter/Couplers are used whenever it is necessary to split or combine outputs from optical transmitters or inputs to receivers. Operators should be aware that a small insertion loss
(typically 3-4dB) is common with these type of couplers. Single Mode Optical Splitter/Coupler (98-100001) It is an O.E.M unit featuring almost negligible insertion loss to the F/O signal. Extreme caution should be exercised when handling these devices. Special attention should be shown to the connectors; repair of a broken Splitter/Coupler is not possible; replacement is the only option. In the Fibre Optic Splitter (55-165507) in University Station Master Site 1 (80-330552-1), Single Mode Optical Splitter/Coupler (98-100001) is used to split the optical signal from the FO TX module in F/O Link Subsystem (98-700001) into two equal paths.

Bandpass Filter (02-007206) in order to optimise The bandpass filters are multi-section designs with a bandwidth dependent upon the passband frequencies, (both tuned to customer requirements). The response shape is basically Chebyshev with a passband design ripple of 0.1dB. The filters are of slot coupled, folded combline design, and are carefully aligned during manufacture loss, VSWR and intermodulation characteristics of the unit. The tuned elements are silver-plated to reduce surface ohmic losses and maintain a good VSWR figure and 50 load at the input and output ports. Being passive devices, the bandpass filters should have an extremely long operational life and require no maintenance. Should a filter be suspect, it is usually most time efficient to replace the module rather than attempt repair or re-tuning. No adjustments should be attempted without full network sweep analysis facilities to monitor both insertion loss and VSWR simultaneously. 02-007206 Specification insertion the PARAMETER SPECIFICATION Response type Chebyshev Frequency range 800 - 950MHz *

(AGC) system used in 800MHz FO Hub Amplifier + Filters (55-165601); 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the down link 800MHz FO Hub Amplifier + Filters (55-165601) is fitted with two differing types of Automatic Gain Control (AGC) system, one linear, and one logarithmic. The AGC with logarithmic detector (17-
001117) is fitted in the uplink path and the AGC with linear detector (17-001109) is fitted in the downlink path The AFL Automatic Gain Control system consists of two units, a detector/amplifier and an attenuator. The detector/amplifier unit is inserted in the RF path on the output of the power amplifier, and the attenuator is situated in the RF path between the 1st and 2nd stages of amplification. 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the down link The attenuator comprises a 50 P.I.N diode, voltage-variable attenuator with a range of 3 to 30dB. The attenuation is controlled by a DC voltage which is derived from the associated detector controller board. Normally the attenuator is at minimum attenuation. The detector/amplifier unit monitors the RF level being delivered by the power amplifier, and when a certain threshold is reached it begins to increase the value of the attenuator to limit the RF output to the (factory set) threshold. Therefore overloading of the power amplifier is avoided. The factory set threshold is 1dB below the Enhancer 1dB compression point. Some adjustment of this AGC threshold level is possible, a 10dB range is mostly achieved. It is not recommended under any circumstances to adjust the AGC threshold to a level greater than the 1dB compression point as system degradation will occur. The detector comprises of a 50 transmission line with a resistive tap which samples a small portion of the mainline power. The sampled signal is amplified and fed to a conventional half wave diode rectifier, the output of which is a DC voltage proportional to the RF input signal. This DC voltage is passed via an inverting DC amplifier with integrating characteristics, to the output, which drives the attenuation control line of the corresponding AGC attenuator. This unit is fitted at some earlier point in the RF circuit. For small signals, below AGC onset, the output control line will be close to 12V and the AGC attenuator will have minimum attenuation. As the signal level increases the control line voltage will fall, increasing the attenuator value and keeping the system output level at a constant value.

Bandpass Filter (02-007206) in order to optimise The bandpass filters are multi-section designs with a bandwidth dependent upon the passband frequencies, (both tuned to customer requirements). The response shape is basically Chebyshev with a passband design ripple of 0.1dB. The filters are of slot coupled, folded combline design, and are carefully aligned during manufacture loss, VSWR and intermodulation characteristics of the unit. The tuned elements are silver-plated to reduce surface ohmic losses and maintain a good VSWR figure and 50 load at the input and output ports. Being passive devices, the bandpass filters should have an extremely long operational life and require no maintenance. Should a filter be suspect, it is usually most time efficient to replace the module rather than attempt repair or re-tuning. No adjustments should be attempted without full network sweep analysis facilities to monitor both insertion loss and VSWR simultaneously. 02-007206 Specification insertion the PARAMETER SPECIFICATION Response type Chebyshev Frequency range 800 - 950MHz *

Switched Attenuator 0.25Watt, 0 - 30dB (10-000701) In many practical applications for Cell Enhancers etc., the gain in each path is found to be excessive. Therefore, provision is made within the unit for the setting of attenuation in each path, to reduce the gain. Switched Attenuator 10-000701 provides attenuation from 0 to 30dB in 2 dB steps The attenuation is simply set using the four miniature toggle switches on the top of each unit. Each switch is clearly marked with the attenuation it provides, and the total attenuation in line is the sum of the values switched in. They are designed to maintain an accurate 50 impedance over their operating frequency at both input and output. 10-000701 Specification PARAMETER SPECIFICATION Attenuation Values 0-30dB Attenuation Steps 2, 4, 8 and 16dB Power Handling 0.25 Watt Attenuation Accuracy 1.0 dB Frequency Range DC to 1GHz Impedance 50 Connectors SMA VSWR 1.3:1 Weight 0.2kg Temperature range operation storage

Bandpass Filter (02-007206) in order to optimise The bandpass filters are multi-section designs with a bandwidth dependent upon the passband frequencies, (both tuned to customer requirements). The response shape is basically Chebyshev with a passband design ripple of 0.1dB. The filters are of slot coupled, folded combline design, and are carefully aligned during manufacture loss, VSWR and intermodulation characteristics of the unit. The tuned elements are silver-plated to reduce surface ohmic losses and maintain a good VSWR figure and 50 load at the input and output ports. Being passive devices, the bandpass filters should have an extremely long operational life and require no maintenance. Should a filter be suspect, it is usually most time efficient to replace the module rather than attempt repair or re-tuning. No adjustments should be attempted without full network sweep analysis facilities to monitor both insertion loss and VSWR simultaneously. 02-007206 Specification insertion the PARAMETER SPECIFICATION Response type Chebyshev Frequency range 800 - 950MHz *

Switched Attenuator 0.25W, 0 - 15dB (10-000901) In many practical applications for Cell Enhancers etc., the gain in each path is found to be excessive. Therefore, provision is made within the unit for the setting of attenuation in each path, to reduce the gain. 10-000901 provides attenuation from 0 - 15dB in 2 dB steps The attenuation is simply set using the four miniature toggle switches on the top of each unit. Each switch is clearly marked with the attenuation it provides, and the total attenuation in line is the sum of the values switched in. They are designed to maintain an accurate 50 impedance over their operating frequency at both input and output. 10-000901 Specification PARAMETER Attenuation Values 0-15dB Attenuation Steps 1, 2, 4 and 8dB SPECIFICATION Power Handling 0.25 Watt Attenuation Accuracy 1.0 dB Frequency Range DC to 1GHz Impedance 50 Connectors SMA VSWR 1.3:1 Weigh 0.2kg Temperature range operation -20C to +60C storage -40C to +70C 12.4.1.6.

The AGC with logarithmic detector (17-001117) is fitted in the uplink path and the AGC with linear detector (17-001109) is fitted in the downlink path The AFL Automatic Gain Control system consists of two units, a detector/amplifier and an attenuator. The detector/amplifier unit is inserted in the RF path on the output of the power amplifier, and the attenuator is situated in the RF path between the 1st and 2nd stages of amplification. 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the downlink The attenuator comprises a 50 P.I.N diode, voltage-variable attenuator with a range of 3 to 30dB. The attenuation is controlled by a DC voltage which is derived from the associated detector controller board. Normally the attenuator is at minimum attenuation. The detector/amplifier unit monitors the RF level being delivered by the power amplifier, and when a certain threshold is reached it begins to increase the value of the attenuator to limit the RF output to the (factory set) threshold. Therefore overloading of the power amplifier is avoided. The factory set threshold is 1dB below the Enhancer 1dB compression point. Some adjustment of this AGC threshold level is possible, a 10dB range is mostly achieved. It is not recommended under any circumstances to adjust the AGC threshold to a level greater than the 1dB compression point as system degradation will occur. STTRS DOCUMENTATION Document Number 80-330501HBKM Issue A - Draft Page 222 of 500 The detector comprises of a 50 transmission line with a resistive tap which samples a small portion of the mainline power. The sampled signal is amplified and fed to a conventional half wave diode rectifier, the output of which is a DC voltage proportional to the RF input signal. This DC voltage is passed via an inverting DC amplifier with integrating characteristics, to the output, which drives the attenuation control line of the corresponding AGC attenuator. This unit is fitted at some earlier point in the RF circuit. For small signals, below AGC onset, the output control line will be close to 12V and the AGC attenuator will have minimum attenuation. As the signal level increases the control line voltage will fall, increasing the attenuator value and keeping the system output level at a constant value.

Dual Diode Assembly (94-100004) The purpose of these dual diode assemblies is to allow two DC voltage sources to be combined, so that the main DC rail within the equipment can be sourced from either a mains driven PSU, or externally through an XLR connector or from dual mains driven PSUs . They are very heavy-duty diodes and they prevent any reverse current from flowing back to their source or the alternative supply rail. Combining diodes such as these will also be used if the equipment is to be powered from external back-up batteries.

Bandpass Filter (02-007206) in order to optimise The bandpass filters are multi-section designs with a bandwidth dependent upon the passband frequencies, (both tuned to customer requirements). The response shape is basically Chebyshev with a passband design ripple of 0.1dB. The filters are of slot coupled, folded combline design, and are carefully aligned during manufacture loss, VSWR and intermodulation characteristics of the unit. The tuned elements are silver-plated to reduce surface ohmic losses and maintain a good VSWR figure and 50 load at the input and output ports. Being passive devices, the bandpass filters should have an extremely long operational life and require no maintenance. Should a filter be suspect, it is usually most time efficient to replace the module rather than attempt repair or re-tuning. No adjustments should be attempted without full network sweep analysis facilities to monitor both insertion loss and VSWR simultaneously. 02-007206 Specification insertion the PARAMETER SPECIFICATION Response type Chebyshev Frequency range 800 - 950MHz *

Switched Attenuator 0.25W, 0 - 15dB (10-000901) In many practical applications for Cell Enhancers etc., the gain in each path is found to be excessive. Therefore, provision is made within the unit for the setting of attenuation in each path, to reduce the gain. 10-000901 provides attenuation from 0 - 15dB in 2 dB steps The attenuation is simply set using the four miniature toggle switches on the top of each unit. Each switch is clearly marked with the attenuation it provides, and the total attenuation in line is the sum of the values switched in.

(AGC) system used in 700MHz Line Amplifier (55-165704); 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the downlink 700MHz Line Amplifier (55-165704) is fitted with two differing types of Automatic Gain Control (AGC) system, one linear, and one logarithmic. The AGC with logarithmic detector (17-001117) is fitted in the uplink path and the AGC with linear detector (17-001109) is fitted in the downlink path The AFL Automatic Gain Control system consists of two units, a detector/amplifier and an attenuator. The detector/amplifier unit is inserted in the RF path on the output of the power amplifier, and the attenuator is situated in the RF path between the 1st and 2nd stages of amplification. 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the downlink The attenuator comprises a 50 P.I.N diode, voltage-variable attenuator with a range of 3 to 30dB. The attenuation is controlled by a DC voltage which is derived from the associated detector controller board. Normally the attenuator is at minimum attenuation. The detector/amplifier unit monitors the RF level being delivered by the power amplifier, and when a certain threshold is reached it begins to increase the value of the attenuator to limit the RF output to the (factory set) threshold. Therefore overloading of the power amplifier is avoided. The factory set threshold is 1dB below the Enhancer 1dB compression point. Some adjustment of this AGC threshold level is possible, a 10dB range is mostly achieved. It is not recommended under any circumstances to adjust the AGC threshold to a level greater than the 1dB compression point as system degradation will occur. STTRS DOCUMENTATION Document Number 80-330501HBKM Issue A - Draft Page 233 of 500 The detector comprises of a 50 transmission line with a resistive tap which samples a small portion of the mainline power. The sampled signal is amplified and fed to a conventional half wave diode rectifier, the output of which is a DC voltage proportional to the RF input signal. This DC voltage is passed via an inverting DC amplifier with integrating characteristics, to the output, which drives the attenuation control line of the corresponding AGC attenuator. This unit is fitted at some earlier point in the RF circuit. For small signals, below AGC onset, the output control line will be close to 12V and the AGC attenuator will have minimum attenuation. As the signal level increases the control line voltage will fall, increasing the attenuator value and keeping the system output level at a constant value.

It is equipped with a single dual pole change-over relay RL1, with completely isolated wiring, accessed via a 15 way in-line connector. The relay is provided with polarity protection diodes and diodes for suppressing the transients caused by "flywheel effect" which can destroy switching transistors or induce spikes on neighbouring circuits. Its common use is to amalgamate all the alarm signals into one, volts-free relay contact pair for the main alarm system. 80-008901 Specification PARAMETER SPECIFICATION Operating voltage 8 to 30V (floating earth) Alarm threshold Vcc - 1.20 volt +15%

Dual Diode Assembly (94-100004) The purpose of these dual diode assemblies is to allow two DC voltage sources to be combined, so that the main DC rail within the equipment can be sourced from either a mains driven PSU, or externally through an XLR connector or from dual mains driven PSUs . They are very heavy-duty diodes and they prevent any reverse current from flowing back to their source or the alternative supply rail. Combining diodes such as these will also be used if the equipment is to be powered from external back-up batteries. 12.4.2.12. DC/DC Converter 96-200047 96-200047 is an O.E.M. high power device with a wide input range and 12.5 amp @ 12V (150Watts) output capability used to derive a 12V fixed voltage power supply rail from a higher voltage supply, in this case 12V.

If a fault is suspected, then the output voltage from the power supply may be measured on its output terminals. This is typically set to 12.2V. The adjustment potentiometer will be found close to the DC output terminals. All the PSUs used in AFL Cell Enhancers are capable of operation from either 110 or 220V nominal AC supplies. The line voltage is sensed automatically, so no adjustment or link setting is needed by the operator. 96-300052 Specification AC Input Supply DC Output Supply 110 or 220V nominal Voltage 85 - 265V AC

Bandpass Filter (02-007206) in order to optimise The bandpass filters are multi-section designs with a bandwidth dependent upon the passband frequencies, (both tuned to customer requirements). The response shape is basically Chebyshev with a passband design ripple of 0.1dB. The filters are of slot coupled, folded combline design, and are carefully aligned during manufacture loss, VSWR and intermodulation characteristics of the unit. The tuned elements are silver-plated to reduce surface ohmic losses and maintain a good VSWR figure and 50 load at the input and output ports. Being passive devices, the bandpass filters should have an extremely long operational life and require no maintenance. Should a filter be suspect, it is usually most time efficient to replace the module rather than attempt repair or re-tuning. No adjustments should be attempted without full network sweep analysis facilities to monitor both insertion loss and VSWR simultaneously. 02-007206 Specification insertion the PARAMETER SPECIFICATION Response type Chebyshev Frequency range 800 - 950MHz *

(AGC) system used in 800MHz Line Amplifier (55-165703); 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the downlink 800MHz Line Amplifier (55-165703) is fitted with two differing types of Automatic Gain Control (AGC) system, one linear, and one logarithmic. The AGC with logarithmic detector (17-001117) is fitted in the uplink path and the AGC with linear detector (17-001109) is fitted in the downlink path The AFL Automatic Gain Control system consists of two units, a detector/amplifier and an attenuator. The detector/amplifier unit is inserted in the RF path on the output of the power amplifier, and the attenuator is situated in the RF path between the 1st and 2nd stages of amplification. 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the downlink The attenuator comprises a 50 P.I.N diode, voltage-variable attenuator with a range of 3 to 30dB. The attenuation is controlled by a DC voltage which is derived from the associated detector controller board. Normally the attenuator is at minimum attenuation. The detector/amplifier unit monitors the RF level being delivered by the power amplifier, and when a certain threshold is reached it begins to increase the value of the attenuator to limit the RF output to the (factory set) threshold. Therefore overloading of the power amplifier is avoided. The factory set threshold is 1dB below the Enhancer 1dB compression point. Some adjustment of this AGC threshold level is possible, a 10dB range is mostly achieved. It is not recommended under any circumstances to adjust the AGC threshold to a level greater than the 1dB compression point as system degradation will occur. STTRS DOCUMENTATION Document Number 80-330501HBKM Issue A - Draft Page 268 of 500 The detector comprises of a 50 transmission line with a resistive tap which samples a small portion of the mainline power. The sampled signal is amplified and fed to a conventional half wave diode rectifier, the output of which is a DC voltage proportional to the RF input signal. This DC voltage is passed via an inverting DC amplifier with integrating characteristics, to the output, which drives the attenuation control line of the corresponding AGC attenuator. This unit is fitted at some earlier point in the RF circuit. For small signals, below AGC onset, the output control line will be close to 12V and the AGC attenuator will have minimum attenuation. As the signal level increases the control line voltage will fall, increasing the attenuator value and keeping the system output level at a constant value.

Dual Diode Assembly (94-100004) The purpose of these dual diode assemblies is to allow two DC voltage sources to be combined, so that the main DC rail within the equipment can be sourced from either a mains driven PSU, or externally through an XLR connector or from dual mains driven PSUs . They are very heavy-duty diodes and they prevent any reverse current from flowing back to their source or the alternative supply rail. Combining diodes such as these will also be used if the equipment is to be powered from external back-up batteries.

Bandpass Filter (02-007206) in order to optimise The bandpass filters are multi-section designs with a bandwidth dependent upon the passband frequencies, (both tuned to customer requirements). The response shape is basically Chebyshev with a passband design ripple of 0.1dB. The filters are of slot coupled, folded combline design, and are carefully aligned during manufacture loss, VSWR and intermodulation characteristics of the unit. The tuned elements are silver-plated to reduce surface ohmic losses and maintain a good VSWR figure and 50 load at the input and output ports. Being passive devices, the bandpass filters should have an extremely long operational life and require no maintenance. Should a filter be suspect, it is usually most time efficient to replace the module rather than attempt repair or re-tuning. No adjustments should be attempted without full network sweep analysis facilities to monitor both insertion loss and VSWR simultaneously. 02-007206 Specification insertion the PARAMETER SPECIFICATION Response type Chebyshev Frequency range 800 - 950MHz *

(AGC) system used in 700MHz Line Amplifier (55-165704); 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the downlink 700MHz Line Amplifier (55-165704) is fitted with two differing types of Automatic Gain Control (AGC) system, one linear, and one logarithmic. The AGC with logarithmic detector (17-001117) is fitted in the uplink path and the AGC with linear detector (17-001109) is fitted in the downlink path The AFL Automatic Gain Control system consists of two units, a detector/amplifier and an attenuator. The detector/amplifier unit is inserted in the RF path on the output of the power amplifier, and the attenuator is situated in the RF path between the 1st and 2nd stages of amplification. 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the downlink The attenuator comprises a 50 P.I.N diode, voltage-variable attenuator with a range of 3 to 30dB. The attenuation is controlled by a DC voltage which is derived from the associated detector controller board. Normally the attenuator is at minimum attenuation. The detector/amplifier unit monitors the RF level being delivered by the power amplifier, and when a certain threshold is reached it begins to increase the value of the attenuator to limit the RF output to the (factory set) threshold. Therefore overloading of the power amplifier is avoided. The factory set threshold is 1dB below the Enhancer 1dB compression point. Some adjustment of this AGC threshold level is possible, a 10dB range is mostly achieved. It is not recommended under any circumstances to adjust the AGC threshold to a level greater than the 1dB compression point as system degradation will occur. STTRS DOCUMENTATION Document Number 80-330501HBKM Issue A - Draft Page 279 of 500 The detector comprises of a 50 transmission line with a resistive tap which samples a small portion of the mainline power. The sampled signal is amplified and fed to a conventional half wave diode rectifier, the output of which is a DC voltage proportional to the RF input signal. This DC voltage is passed via an inverting DC amplifier with integrating characteristics, to the output, which drives the attenuation control line of the corresponding AGC attenuator. This unit is fitted at some earlier point in the RF circuit. For small signals, below AGC onset, the output control line will be close to 12V and the AGC attenuator will have minimum attenuation. As the signal level increases the control line voltage will fall, increasing the attenuator value and keeping the system output level at a constant value.

It is equipped with a single dual pole change-over relay RL1, with completely isolated wiring, accessed via a 15 way in-line connector. The relay is provided with polarity protection diodes and diodes for suppressing the transients caused by "flywheel effect" which can destroy switching transistors or induce spikes on neighbouring circuits. Its common use is to amalgamate all the alarm signals into one, volts-free relay contact pair for the main alarm system. 80-008901 Specification PARAMETER SPECIFICATION Operating voltage 8 to 30V (floating earth) Alarm threshold Vcc - 1.20 volt +15%

Dual Diode Assembly (94-100004) The purpose of these dual diode assemblies is to allow two DC voltage sources to be combined, so that the main DC rail within the equipment can be sourced from either a mains driven PSU, or externally through an XLR connector or from dual mains driven PSUs . They are very heavy-duty diodes and they prevent any reverse current from flowing back to their source or the alternative supply rail. Combining diodes such as these will also be used if the equipment is to be powered from external back-up batteries. 16.4.2.12. DC/DC Converter 96-200047 96-200047 is an O.E.M. high power device with a wide input range and 12.5 amp @ 12V (150Watts) output capability used to derive a 12V fixed voltage power supply rail from a higher voltage supply, in this case 12V.

If a fault is suspected, then the output voltage from the power supply may be measured on its output terminals. This is typically set to 12.2V. The adjustment potentiometer will be found close to the DC output terminals. All the PSUs used in AFL Cell Enhancers are capable of operation from either 110 or 220V nominal AC supplies. The line voltage is sensed automatically, so no adjustment or link setting is needed by the operator. 96-300052 Specification AC Input Supply DC Output Supply 110 or 220V nominal Voltage 85 - 265V AC

(AGC) system used in 800MHz Line Amplifier (no NPSPAC) (55-165705); 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the downlink 800MHz Line Amplifier (no NPSPAC) (55-165705) is fitted with two differing types of Automatic Gain Control (AGC) system, one linear, and one logarithmic. The AGC with logarithmic detector (17-
001117) is fitted in the uplink path and the AGC with linear detector (17-001109) is fitted in the downlink path The AFL Automatic Gain Control system consists of two units, a detector/amplifier and an attenuator. The detector/amplifier unit is inserted in the RF path on the output of the power amplifier, and the attenuator is situated in the RF path between the 1st and 2nd stages of amplification. 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the downlink The attenuator comprises a 50 P.I.N diode, voltage-variable attenuator with a range of 3 to 30dB. The attenuation is controlled by a DC voltage which is derived from the associated detector controller board. Normally the attenuator is at minimum attenuation. The detector/amplifier unit monitors the RF level being delivered by the power amplifier, and when a certain threshold is reached it begins to increase the value of the attenuator to limit the RF output to the (factory set) threshold. Therefore overloading of the power amplifier is avoided. The factory set threshold is 1dB below the Enhancer 1dB compression point. Some adjustment of this AGC threshold level is possible, a 10dB range is mostly achieved. It is not recommended under any circumstances to adjust the AGC threshold to a level greater than the 1dB compression point as system degradation will occur. The detector comprises of a 50 transmission line with a resistive tap which samples a small portion of the mainline power. The sampled signal is amplified and fed to a conventional half wave diode rectifier, the output of which is a DC voltage proportional to the RF input signal. This DC voltage is passed via an inverting DC amplifier with integrating characteristics, to the output, which drives the attenuation control line of the corresponding AGC attenuator. This unit is fitted at some earlier point in the RF circuit. For small signals, below AGC onset, the output control line will be close to 12V and the AGC attenuator will have minimum attenuation. As the signal level increases the control line voltage will fall, increasing the attenuator value and keeping the system output level at a constant value.

Bandpass Filter (02-012701) The bandpass filters are multi-section designs with a bandwidth dependent upon the passband frequencies, (both tuned to customer requirements). The response shape is basically Chebyshev with a passband design ripple of 0.1dB. The filters are of combline design and are carefully aligned during manufacture in order to optimise the insertion loss, VSWR and intermodulation characteristics of the unit. The tuned elements are silver-plated to reduce surface ohmic losses and maintain a good VSWR figure and 50 load at the input and output ports. Being passive devices, the bandpass filters should have an extremely long operational life and require no maintenance. Should a filter be suspect, it is usually most time efficient to replace the module rather than attempt repair or re-tuning. No adjustments should be attempted without full network sweep analysis facilities to monitor both insertion loss and VSWR simultaneously. 02-012701 Specification PARAMETER SPECIFICATION Frequency range 1805 1880 MHz *

Therefore, provision is made within the unit for the setting of attenuation in each path, to reduce the gain. 10-000901 provides attenuation from 0 - 15dB in 2 dB steps The attenuation is simply set using the four miniature toggle switches on the top of each unit.

(AGC) system used in 800MHz Line Amplifier (55-165701); 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the downlink 800MHz Line Amplifier (55-165701) is fitted with two differing types of Automatic Gain Control (AGC) system, one linear, and one logarithmic. The AGC with logarithmic detector (17-001117) is fitted in the uplink path and the AGC with linear detector (17-001109) is fitted in the downlink path The AFL Automatic Gain Control system consists of two units, a detector/amplifier and an attenuator. The detector/amplifier unit is inserted in the RF path on the output of the power amplifier, and the attenuator is situated in the RF path between the 1st and 2nd stages of amplification. 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the downlink The attenuator comprises a 50 P.I.N diode, voltage-variable attenuator with a range of 3 to 30dB. The attenuation is controlled by a DC voltage which is derived from the associated detector controller board. STTRS DOCUMENTATION Document Number 80-330501HBKM Issue A - Draft Page 328 of 500 Normally the attenuator is at minimum attenuation. The detector/amplifier unit monitors the RF level being delivered by the power amplifier, and when a certain threshold is reached it begins to increase the value of the attenuator to limit the RF output to the (factory set) threshold. Therefore overloading of the power amplifier is avoided. The factory set threshold is 1dB below the Enhancer 1dB compression point. Some adjustment of this AGC threshold level is possible, a 10dB range is mostly achieved. It is not recommended under any circumstances to adjust the AGC threshold to a level greater than the 1dB compression point as system degradation will occur. The detector comprises of a 50 transmission line with a resistive tap which samples a small portion of the mainline power. The sampled signal is amplified and fed to a conventional half wave diode rectifier, the output of which is a DC voltage proportional to the RF input signal. This DC voltage is passed via an inverting DC amplifier with integrating characteristics, to the output, which drives the attenuation control line of the corresponding AGC attenuator. This unit is fitted at some earlier point in the RF circuit. For small signals, below AGC onset, the output control line will be close to 12V and the AGC attenuator will have minimum attenuation. As the signal level increases the control line voltage will fall, increasing the attenuator value and keeping the system output level at a constant value.

It is equipped with a single dual pole change-over relay RL1, with completely isolated wiring, accessed via a 15 way in-line connector. The relay is provided with polarity protection diodes and diodes for suppressing the transients caused by "flywheel effect" which can destroy switching transistors or induce spikes on neighbouring circuits. Its common use is to amalgamate all the alarm signals into one, volts-free relay contact pair for the main alarm system.

Dual Diode Assembly (94-100004) The purpose of these dual diode assemblies is to allow two DC voltage sources to be combined, so that the main DC rail within the equipment can be sourced from either a mains driven PSU, or externally through an XLR connector or from dual mains driven PSUs. They are very heavy-duty diodes and they prevent any reverse current from flowing back to their source or the alternative supply rail. Combining diodes such as these will also be used if the equipment is to be powered from external back-up batteries. 18.3.3.11.

If a fault is suspected, then the output voltage from the power supply may be measured on its output terminals. This is typically set to 12.2V. The adjustment potentiometer will be found close to the DC output terminals. All the PSUs used in AFL Cell Enhancers are capable of operation from either 110 or 220V nominal AC supplies.

(AGC) system used in 700MHz Line Amplifier (55-165702); 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the downlink 700MHz Line Amplifier (55-165702) is fitted with two differing types of Automatic Gain Control (AGC) system, one linear, and one logarithmic. The AGC with logarithmic detector (17-001117) is fitted in the uplink path and the AGC with linear detector (17-001109) is fitted in the downlink path The AFL Automatic Gain Control system consists of two units, a detector/amplifier and an attenuator. The detector/amplifier unit is inserted in the RF path on the output of the power amplifier, and the attenuator is situated in the RF path between the 1st and 2nd stages of amplification. 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the downlink The attenuator comprises a 50 P.I.N diode, voltage-variable attenuator with a range of 3 to 30dB. The attenuation is controlled by a DC voltage which is derived from the associated detector controller board. STTRS DOCUMENTATION Document Number 80-330501HBKM Issue A - Draft Page 338 of 500 Normally the attenuator is at minimum attenuation. The detector/amplifier unit monitors the RF level being delivered by the power amplifier, and when a certain threshold is reached it begins to increase the value of the attenuator to limit the RF output to the (factory set) threshold. Therefore overloading of the power amplifier is avoided. The factory set threshold is 1dB below the Enhancer 1dB compression point. Some adjustment of this AGC threshold level is possible, a 10dB range is mostly achieved. It is not recommended under any circumstances to adjust the AGC threshold to a level greater than the 1dB compression point as system degradation will occur. The detector comprises of a 50 transmission line with a resistive tap which samples a small portion of the mainline power. The sampled signal is amplified and fed to a conventional half wave diode rectifier, the output of which is a DC voltage proportional to the RF input signal. This DC voltage is passed via an inverting DC amplifier with integrating characteristics, to the output, which drives the attenuation control line of the corresponding AGC attenuator. This unit is fitted at some earlier point in the RF circuit. For small signals, below AGC onset, the output control line will be close to 12V and the AGC attenuator will have minimum attenuation. As the signal level increases the control line voltage will fall, increasing the attenuator value and keeping the system output level at a constant value.

Bandpass Filter (02-007206) in order to optimise The bandpass filters are multi-section designs with a bandwidth dependent upon the passband frequencies, (both tuned to customer requirements). The response shape is basically Chebyshev with a passband design ripple of 0.1dB. The filters are of slot coupled, folded combline design, and are carefully aligned during manufacture loss, VSWR and intermodulation characteristics of the unit. The tuned elements are silver-plated to reduce surface ohmic losses and maintain a good VSWR figure and 50 load at the input and output ports. Being passive devices, the bandpass filters should have an extremely long operational life and require no maintenance. Should a filter be suspect, it is usually most time efficient to replace the module rather than attempt repair or re-tuning. No adjustments should be attempted without full network sweep analysis facilities to monitor both insertion loss and VSWR simultaneously. 02-007206 Specification insertion the PARAMETER SPECIFICATION Response type Chebyshev Frequency range 800 - 950MHz *

Switched Attenuator 0.25W, 0 - 15dB (10-000901) In many practical applications for Cell Enhancers etc., the gain in each path is found to be excessive. Therefore, provision is made within the unit for the setting of attenuation in each path, to reduce the gain. 10-000901 provides attenuation from 0 - 15dB in 2 dB steps The attenuation is simply set using the four miniature toggle switches on the top of each unit. Each switch is clearly marked with the attenuation it provides, and the total attenuation in line is the sum of the values switched in.

Bandpass Filter (02-007206) in order to optimise The bandpass filters are multi-section designs with a bandwidth dependent upon the passband frequencies, (both tuned to customer requirements). The response shape is basically Chebyshev with a passband design ripple of 0.1dB. The filters are of slot coupled, folded combline design, and are carefully aligned during manufacture loss, VSWR and intermodulation characteristics of the unit. The tuned elements are silver-plated to reduce surface ohmic losses and maintain a good VSWR figure and 50 load at the input and output ports. Being passive devices, the bandpass filters should have an extremely long operational life and require no maintenance. Should a filter be suspect, it is usually most time efficient to replace the module rather than attempt repair or re-tuning. No adjustments should be attempted without full network sweep analysis facilities to monitor both insertion loss and VSWR simultaneously. 02-007206 Specification insertion the PARAMETER SPECIFICATION Response type Chebyshev Frequency range 800 - 950MHz *

Switched Attenuator 0.25W, 0 - 15dB (10-000901) In many practical applications for Cell Enhancers etc., the gain in each path is found to be excessive. Therefore, provision is made within the unit for the setting of attenuation in each path, to reduce the gain. 10-000901 provides attenuation from 0 - 15dB in 2 dB steps The attenuation is simply set using the four miniature toggle switches on the top of each unit. Each switch is clearly marked with the attenuation it provides, and the total attenuation in line is the sum of the values switched in. They are designed to maintain an accurate 50 impedance over their operating frequency at both input and output. 10-000901 Specification PARAMETER Attenuation Values 0-15dB Attenuation Steps 1, 2, 4 and 8dB SPECIFICATION Power Handling 0.25 Watt Attenuation Accuracy 1.0 dB Frequency Range DC to 1GHz Impedance 50 Connectors SMA VSWR 1.3:1 Weigh 0.2kg Temperature range operation -20C to +60C storage -40C to +70C 19.3.4.6. Low Noise Amplifier (11-006702) The Gallium-Arsenide low noise amplifiers used in 800MHz Line Amplifier (55-165703) are double stage, solid-state low noise amplifiers. Class A circuitry is used throughout the units to ensure excellent linearity and extremely low noise over a very wide dynamic range. The active devices are very moderately rated to provide a long trouble-free working life. There are no adjustments on these amplifiers, and in the unlikely event of a failure, then the complete amplifier should be replaced. This amplifier features its own in-built alarm system which gives a volt-free relay contact type alarm that is easily integrated into the main alarm system. 11-006702 Specification PARAMETER SPECIFICATION Frequency range 800 1000MHz Bandwidth <200MHz Gain 29dB (typical) 1dB Compression point 20dBm OIP3 33dBm Input/Output return loss >18dB Noise figure 1.3dB (typical) Power consumption 180mA @ 24V DC Supply voltage 10-24V DC Connectors SMA female operational

(AGC) system used in 700MHz Line Amplifier (55-165702); 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the downlink 700MHz Line Amplifier (55-165702) is fitted with two differing types of Automatic Gain Control (AGC) system, one linear, and one logarithmic. The AGC with logarithmic detector (17-001117) is fitted in the uplink path and the AGC with linear detector (17-001109) is fitted in the downlink path The AFL Automatic Gain Control system consists of two units, a detector/amplifier and an attenuator. The detector/amplifier unit is inserted in the RF path on the output of the power amplifier, and the attenuator is situated in the RF path between the 1st and 2nd stages of amplification. 17-001117 and 17-001201 are paired for use in the uplink and 17-001109 and 17-001201 are paired for use in the downlink The attenuator comprises a 50 P.I.N diode, voltage-variable attenuator with a range of 3 to 30dB. The attenuation is controlled by a DC voltage which is derived from the associated detector controller board. STTRS DOCUMENTATION Document Number 80-330501HBKM Issue A - Draft Page 363 of 500 Normally the attenuator is at minimum attenuation. The detector/amplifier unit monitors the RF level being delivered by the power amplifier, and when a certain threshold is reached it begins to increase the value of the attenuator to limit the RF output to the (factory set) threshold. Therefore overloading of the power amplifier is avoided. The factory set threshold is 1dB below the Enhancer 1dB compression point. Some adjustment of this AGC threshold level is possible, a 10dB range is mostly achieved. It is not recommended under any circumstances to adjust the AGC threshold to a level greater than the 1dB compression point as system degradation will occur. The detector comprises of a 50 transmission line with a resistive tap which samples a small portion of the mainline power. The sampled signal is amplified and fed to a conventional half wave diode rectifier, the output of which is a DC voltage proportional to the RF input signal. This DC voltage is passed via an inverting DC amplifier with integrating characteristics, to the output, which drives the attenuation control line of the corresponding AGC attenuator. This unit is fitted at some earlier point in the RF circuit. For small signals, below AGC onset, the output control line will be close to 12V and the AGC attenuator will have minimum attenuation. As the signal level increases the control line voltage will fall, increasing the attenuator value and keeping the system output level at a constant value.

It is equipped with a single dual pole change-over relay RL1, with completely isolated wiring, accessed via a 15 way in-line connector. The relay is provided with polarity protection diodes and diodes for suppressing the transients caused by "flywheel effect" which can destroy switching transistors or induce spikes on neighbouring circuits. Its common use is to amalgamate all the alarm signals into one, volts-free relay contact pair for the main alarm system.

Dual Diode Assembly (94-100004) The purpose of these dual diode assemblies is to allow two DC voltage sources to be combined, so that the main DC rail within the equipment can be sourced from either a mains driven PSU, or externally through an XLR connector or from dual mains driven PSUs. They are very heavy-duty diodes and they prevent any reverse current from flowing back to their source or the alternative supply rail. Combining diodes such as these will also be used if the equipment is to be powered from external back-up batteries. 19.3.4.11. DC/DC Converter 96-200047 96-200047 is an O.E.M. high power device with a wide input range and 12.5 amp @ 12V (150Watts) output capability used to derive a 12V fixed voltage power supply rail from a higher voltage supply, in this case 12V.

If a fault is suspected, then the output voltage from the power supply may be measured on its output terminals. This is typically set to 12.2V. The adjustment potentiometer will be found close to the DC output terminals. All the PSUs used in AFL Cell Enhancers are capable of operation from either 110 or 220V nominal AC supplies.

Switched Attenuator 0.25W, 0 - 15dB (10-000901) In many practical applications for Cell Enhancers etc., the gain in each path is found to be excessive.

Channel Selectivity Module (17-009127) Channel Selectivity Module (17-009127) is employed when requirement dictates that very narrow bandwidths (single operating channels), must be selected from within the operating passband. One channel selectivity module is required for each channel. The Channel Selectivity Module is an Up/Down frequency converter that mixes the incoming channel frequency with a synthesised local oscillator, so that it is down-converted to an Intermediate Frequency (IF) in the upper HF range. An eight pole crystal filter in the IF amplifier provides the required selectivity to define the operating passband of the Cell Enhancer to a single PMR channel. The same local oscillator then converts the selected IF signal back to the channel frequency. Selectivity is obtained from a fixed bandwidth block filter operating at an intermediate frequency (IF) in the low VHF range. This filter may be internal to the channel selectivity module (Crystal or SAW filter) or an externally mounted bandpass filter, (LC or Helical Resonator). Various IF bandwidths can therefore be accommodated. A synthesized Local Oscillator is employed in conjunction with high performance frequency mixers, to translate between the signal frequency and IF. The operating frequency of each channel selectivity module is set by the programming of channel selectivity module frequencies and is achieved digitally, via hard wired links, banks of DIP switches, or via an onboard RS232 control module, providing the ability to remotely set channel frequencies. Automatic Level Control (ALC) is provided within each channel selectivity module such that the output level is held constant for high level input signals. This feature prevents saturation of the output mixer and of the associated amplifiers. Alarms within the module inhibit the channel if the synthesised frequency is not locked. The synthesiser will not usually go out of lock unless a frequency far out of band is programmed. The channel selectivity module is extremely complex and, with the exception of channel frequency programming within the design bandwidth, it cannot be adjusted or repaired without extensive laboratory facilities and the necessary specialised personnel. If a fault is suspected with any channel selectivity module it should be tested by substitution and the complete, suspect module should then be returned to AFL for investigation. STTRS DOCUMENTATION Document Number 80-330501HBKM Issue A - Draft Page 392 of 500 21.3.1.9. Channel Control Module (17-011501) The operating frequency for each channel in each repeater is programmed by 16 DIL (Dual In Line) switches. The programming switches are mounted in the Channel Control Module. The Channel Selectivity Modules are connected to the Channel Control Module via multi-way ribbon cables. Adjacent to the DIL switches for each channel is a toggle switch to turn on and off individual channels as required. A green LED indicates the power status of each channel. A red LED shows the alarm condition for each channel. An illuminated alarm LED indicates that the synthesiser has not achieved phase lock and that the module is disabled. There is a problem which requires investigation, often a frequency programmed outside the operating frequency range. The following information is necessary before attempting the programming procedure. 1. operating frequency 2. synthesiser channel spacing (step size) 3. synthesiser offset (IF) Programming Procedure Check that the required frequency falls within the operational frequency limits of the Cell Enhancer. For each channel required, subtract the synthesiser offset from the required operating frequency and record the resulting local oscillator frequency. Divide each local oscillator frequency by the channel spacing and check that the result is an integer
(i.e: no remainder). If the synthesiser division ratio is not an integer value, check the required operational frequency and repeat the calculation checking for mistakes. Convert the required local oscillator frequency to synthesiser programming switch state patterns according to the following table. Note: the frequency of the passband will dictate the switch steps used.

Dual Isolator (770MHz) (93-910048) The purpose of fitting an isolator to the output of a transmitter in a multi-transmitter environment is so that each output is afforded a degree of isolation from every other. Without the addition of Isolators, simultaneous transmissions could interfere to create intermodulation products and spurious transmissions would be created which would cause interference. Dual Isolator (93-910048) is a ferro-magnetic RF device, which has directional properties. In the forward direction, RF arriving at the input is passed to the output with minimal attenuation. In the reverse direction, RF arriving at the output due to reflected power from a badly matched load, or due to coupling with another transmitter, is routed into an RF load where it is absorbed. The isolator therefore functions to prevent reflected RF energy reaching the output port of an amplifier where it could cause intermodulation products or premature device failure. Dual Isolator (93-910048) is as its name suggests a two stage device, essentially two isolators in one casing. One isolator stage has an internal 10W load fitted, the second stage needs an external load fitted of sufficient rating to absorb the reflected power levels that can be reasonably expected within the system. In this instance Dual Isolator (93-910048) is fitted with external load 09-000902. 93-910048 Specification Parameter Frequency Range 760-780 MHz Specification Insertion Loss 0.4 dB max.

Dual Diode Assembly (94-100004) The purpose of these dual diode assemblies is to allow two DC voltage sources to be combined, so that the main DC rail within the equipment can be sourced from either a mains driven PSU, or externally through an XLR connector or from dual mains driven PSUs . They are very heavy-duty diodes and they prevent any reverse current from flowing back to their source or the alternative supply rail. Combining diodes such as these will also be used if the equipment is to be powered from external back-up batteries. 21.3.1.13. PSU 24V (96-300060) The power supply unit is a switched-mode type capable of supplying 24V DC at 6.25Amps continuously. Equipment of this type typically requires approximately 2-2.5Amps at 24V DC, so the PSU will be used conservatively ensuring a long operational lifetime. No routine maintenance of the PSU is required. If a fault is suspected, then the output voltage from the power supply may be measured on its output terminals. This is typically set to 24.5V. The output voltage may be varied using a multi-turn adjustment potentiometer mounted close to the DC output terminals. The line input voltage is sensed automatically, so no adjustment or link setting is needed by the operator. 96-300060 Specification AC Input Supply 110 or 220V nominal Voltage 90 to 132 or 180 to 264V

Bandpass Filter (02-007206) in order to optimise The bandpass filters are multi-section designs with a bandwidth dependent upon the passband frequencies, (both tuned to customer requirements). The response shape is basically Chebyshev with a passband design ripple of 0.1dB. The filters are of slot coupled, folded combline design, and are carefully aligned during manufacture loss, VSWR and intermodulation characteristics of the unit. The tuned elements are silver-plated to reduce surface ohmic losses and maintain a good VSWR figure and 50 load at the input and output ports. Being passive devices, the bandpass filters should have an extremely long operational life and require no maintenance. Should a filter be suspect, it is usually most time efficient to replace the module rather than attempt repair or re-tuning. No adjustments should be attempted without full network sweep analysis facilities to monitor both insertion loss and VSWR simultaneously. 02-007206 Specification insertion the PARAMETER SPECIFICATION Response type Chebyshev Frequency range 800 - 950MHz *

AGC System AGC Detector Unit (17-001109) AGC Attenuator Unit (17-001201) EQUIPMENT 700MHz Uplink Amplifier/ Duplexer (50-132104) is fitted with a wide dynamic range Automatic Gain Control (AGC) system. This is fitted in the Uplink path to avoid overloading the amplifiers (with the associated performance degradation) should a mobile be operated very close to the unit. two units, a The AFL wide dynamic range Automatic Gain Control system consists of detector/amplifier and an attenuator. The logarithmic detector/amplifier unit is inserted in the RF path on the output of the power amplifier, and the attenuator is situated in the RF path between the 1st and 2nd stages of amplification. Normally the attenuator is at minimum attenuation. The detector/amplifier unit monitors the RF level being delivered by the power amplifier, and when a certain threshold is reached it begins to increase the value of the attenuator to limit the RF output to the (factory set) threshold. Therefore overloading of the power amplifier is avoided. The factory set threshold is 1dB below the Enhancer 1dB compression point. Some adjustment of this AGC threshold level is possible, a 10dB range is mostly achieved. It is not recommended under any circumstances to adjust the AGC threshold to a level greater than the 1dB compression point as system degradation will occur. The detector comprises of a 50 transmission line with a resistive tap which samples a small portion of the mainline power. The sampled signal is amplified and fed to a conventional half wave diode rectifier, the output of which is a DC voltage proportional to the RF input signal. This DC voltage is passed via an inverting DC amplifier with integrating characteristics, to the output, which drives the attenuation control line of the corresponding AGC attenuator. This unit is fitted at some earlier point in the RF circuit. For small signals, below AGC onset, the output control line will be close to 12V and the AGC attenuator will have minimum attenuation. As the signal level increases the control line voltage will fall, increasing the attenuator value and keeping the system output level at a constant value. The AGC onset level is adjusted by the choice of sampler resistor R1 and by the setting of potentiometer VR1, (factory set at the time of system test) do not adjust unless able to monitor subsequent RF levels. The attenuator comprises a 50 P.I.N diode, voltage-variable attenuator with a range of 3 to 30dB. The attenuation is controlled by a DC voltage which is derived from the associated AGC detector unit.

Dummy Load (80-007401) When a combiner system is used to split or combine RF signals, in many cases it is most cost effective to use a standard stock item 4, 6 or 8 port device where, in fact, only a 3 or 6 port device is needed. In this case the Four Way Splitters (05-003302) each have their unused ports terminated with Dummy Load (80-007401) in order to preserve the correct impedance of the devices over the specified frequency range. This also has the advantage of allowing future expansion capability should extra channels or other functions become necessary. Dummy Load (80-007401) Specification Parameter Specification VSWR

It is equipped with a single dual pole change-over relay RL1, with completely isolated wiring, accessed via a 15 way in-line connector. The relay is provided with polarity protection diodes and diodes for suppressing the transients caused by "flywheel effect" which can destroy switching transistors or induce spikes on neighbouring circuits. Its common use is to amalgamate all the alarm signals into one, volts-free relay contact pair for the main alarm system. 80-008901 Specification PARAMETER SPECIFICATION Operating voltage 8 to 30V (floating earth) Alarm threshold Vcc - 1.20 volt +15%

Dual Diode Assembly (94-100004) The purpose of these dual diode assemblies is to allow two DC voltage sources to be combined, so that the main DC rail within the equipment can be sourced from either a mains driven PSU, or externally through an XLR connector or from dual mains driven PSUs. They are very heavy-duty diodes and they prevent any reverse current from flowing back to their source or the alternative supply rail. Combining diodes such as these will also be used if the equipment is to be powered from external back-up batteries. STTRS DOCUMENTATION Document Number 80-330501HBKM Issue A - Draft Page 406 of 500 21.3.2.15. 12V Switch-Mode PSU (96-300052) No routine maintenance of the PSU is required. If a fault is suspected, then the output voltage from the power supply may be measured on its output terminals. This is typically set to 12.2V. The adjustment potentiometer will be found close to the DC output terminals. The line input voltage is sensed automatically, so no adjustment or link setting is needed by the operator. 96-300052 Specification AC Input Supply DC Output Supply 110 or 220V nominal Voltage 85 - 265V AC (absolute limits) Frequency 47 to 63Hz 12V DC (nominal) Voltage 10.5-13.8V (absolute limits) Current 12.5A STTRS DOCUMENTATION Document Number 80-330501HBKM Issue A - Draft Page 407 of 500 INTERNATIONAL STATION 800MHZ BDA (80-330555-1) 22.

Bandpass Filter (02-007206) in order to optimise The bandpass filters are multi-section designs with a bandwidth dependent upon the passband frequencies, (both tuned to customer requirements). The response shape is basically Chebyshev with a passband design ripple of 0.1dB. The filters are of slot coupled, folded combline design, and are carefully aligned during manufacture loss, VSWR and intermodulation characteristics of the unit. The tuned elements are silver-plated to reduce surface ohmic losses and maintain a good VSWR figure and 50 load at the input and output ports. Being passive devices, the bandpass filters should have an extremely long operational life and require no maintenance. Should a filter be suspect, it is usually most time efficient to replace the module rather than attempt repair or re-tuning. No adjustments should be attempted without full network sweep analysis facilities to monitor both insertion loss and VSWR simultaneously. 02-007206 Specification insertion the PARAMETER SPECIFICATION Response type Chebyshev Frequency range 800 - 950MHz *
