PRODUCT CODES PAGE 11 Receiver Transmitter Control Board removed High-power Amplifier or Integrated PSU Option Figure 3.1 - Layout of the Blade with the top lid 3 DESCRIPTION The Blade is a 1U high by 19 wide rack-mountable unit containing two SRM9000 sub-assemblies, a control card, and a fan bulkhead which mates with the angled front panel and MMI card. There is also provision for fitting a high power amplifier or integrated power supply option. 3.1 VENTILATION In order to provide full-power continuous operation in any orientation and in a 1U envelope, the Blade uses forced air-cooling. A pair of fans draws air in from an air intake located underneath the front lip of the angled front panel. This air is compressed by a baffle that directs the airflow underneath the heatsink of the SRM9000 sub assemblies. A second pair of fans is used for the high-power amplifier option if fitted. Fans are located to maximise the cooling for the transmitting module. Air is exhausted through a grilled area on the rear panel immediately below the electrical connectors. Vent holes in the internal baffle allow a small amount of air to bleed diagonally through the top section of the chassis to ensure that hot spots do not form on the component side of the sub-assemblies. The fans are mounted in a bulkhead located immediately behind the front panel. The front panel, MMI board and fan bulkhead are separately assembled and removed from the unit as sub-assemblies. The fans, loudspeaker and indicator LEDs are all controlled from the MMI PCB that fits into this sub-assembly. The fans are not only speed controlled to minimise noise and wear, but their speed is also monitored to provide early warning of failure. In normal operation, the fans are turned on to full speed to minimise any possibility of a stall, the speed is then turned down based upon equipment temperature. Even if the temperature is very low, fans are always kept running at a low speed. Temperature is sensed from a Thermistor located on the underside of the control board. This Thermistor protrudes into the airflow from the transmit PA module. When installing the Blade it is important to ensure that adequate ventilation is provided for each base station unit. A minimum free-area of 72cm2 is recommended per base station at the inlet AND at the outlet. This should be increased if air has to be drawn through ducts or has to be deflected around corners. Noise and dust build up can be reduced by keeping cabling and other obstructions out of the main airflows. There are no dust filters fitted in this product. If it is to be used in very dirty environments, then additional steps should be taken to prevent ingress of dust as this will affect thermal performance. Filters should only be used in external cabinets if they can be regularly maintained. 3.2 SRM9000 SUB-ASSEMBLY The RF performance of this product is derived from a pair of SRM9000 RF PCBs mounted on a Heatsink sub-assembly that is designed to permit continuous operation at full power. The sub-assembly also provides RF screening, so it is important that it is accurately assembled and reassembled. The sub-assembly has a plate attached to the rear edge with two quarter-turn fasteners for rapid removal. The unit is retained in the Blade chassis by the front edge of the Heatsink that inserts underneath the fan baffle, the rear of the subassembly is held in place by the quick release fasteners. These units are electrically identical to SRM9000 and are also fully interchangeable in the 25W power group (the Transmit module is different for the 100W systems). Control is provided via the 26-way ribbon connector. Power is supplied via the DB-15 connector and RF signals are coupled to the BNC sockets with double-screened cables. 3.3 SPECIFICATIONS 3.3.1 General Channel Bandwidth Modulation 12.5kHz (11K0F3EJN), 20kHz (14K0F3EJN) or 25kHz

Fuse F2 on the fuse-board is a 10A quick-blow, 20 x 5mm component and protects the 24V line to the Power Amplifier, if fitted Fuse F5 on the Xfin Control Card is a 2A quick-blow, 20 x 5mm component and protects the 12V line to the PCB. In event of failure, the reason for the failure should be investigated prior to replacement. The fuse should only be replaced with a correctly specified component. 3.5.4 Ethernet This is a 10/100 base-T RJ45 connection. This is a switch (not a NIC) configuration care should be taken to use the correct cable (crossover or straight-through) when connecting to a network. The use of shielded cables is recommended, especially for VHF installations. The two indicator LEDs, integrated into the connector, show 100Mbps bandwidth detection and traffic activity. A third LED, on the Control Card shows if a connection is present. 1 8 Pin Description 1 2 3 4 5 6 Eth Rx-Data, balanced input 1 Eth Rx-Data, balanced input 2 Eth Tx-Data, balanced output 1 NC NC Eth Tx-Data, balanced output 2 PAGE 20 DESCRIPTION 7 8 NC NC XFIN-BLADE-SM 3.5.5 RS232 Serial (D-Sub) This is a standard DB-9 female RS-232 socket with the following pins connected for DTE operation:

The DSP is responsible for all audio processing including mixing, FFSK encoding/decoding, DTMF encoding/decoding, supervisory tone generation, audio emphasis and speech processing for VOIP between Blades. Booting The DSP downloads the application code from the IXP Network Processor at start up and runs the software entirely in internal memory. RS232 Serial Interface (Rear RJ-45) The rear of the Blade contains a standard RJ-45 Serial connection in order that an engineer may connect a PC to the DSP via an RJ-45 to DB-9 cable. Debug commands may then be issued to the DSP for diagnostic information. CPLD Interface Communications between the IXP Network Processor and the DSP are performed by connecting the data bus on the IXP to the host interface (Lattice LC256V-75T100 CPLD) connecting to the DSP. The IXP writes to the host interface, triggering a DMA on the DSP to copy the data to a buffer. After a packet has been sent, the DMA on the DSP copies data from an outgoing buffer to the host interface port that is read by the IXP. This enables high-speed communications without impacting the performance of the DSP. TECHNICAL DESCRIPTION PAGE 33 4.2.2.4 Power The control board requires a 12V 2000ma supply. Linear regulators are provided to reduce the input voltage down to 10V and 5V for the audio circuits. The input voltage supply is also regulated down to 3.3V for the digital logic via a switched mode power supply. The 1.3V supply for the IXP processor core is generated by a regulator off the 3.3V rail. The 1.2V supply for the DSP core is generated by a diode (controlled by the DSP) off the 3.3V rail. 4.2.2.5 IXP Description The main processor is an IXP42x processor manufactured by INTEL. It consists of a central ARM based processor supported by separate network processor engines for supporting the Ethernet and USB ports. The IXP runs the application code under MontaVista Linux. The application code consists of Trunked Site Control, Inter-Blade Communications, Site Configuration, Fan Control and the LCD menu system. The network processor also provides support to the DSP. The IXP is connected to external flash memory that stores the IXP software. Reset of the IXP is performed reset circuitry monitoring voltage supplies. Watchdog The IXP processor has its own internal watchdog. Fan Control The IXP performs fan control via Maxim Fan Regulator devices, monitoring the temperature of the airflow from the transmitter module using a thermistor (RT1). If the temperature is too high or low, the speed of the fans is adjusted accordingly. Fans are not allowed to stop during normal operation. Each fan generates a tachometer output allowing software to detect a fan failure or potential failure by monitoring fan speed. If one fan fails the speed of the second fan will be increased to compensate. Analogue Outputs Two analogue outputs are provided by a dual-channel Digital to Analogue Converter
(U41). They provide analogue outputs to the Facilities Connector to output, for example, the RSSI level. Analogue Inputs The ADC (U56) has eight analogue inputs available, which are currently used to provide voltage monitoring of the thermistor and the 12V unregulated supply, receive inputs from the PA header and provide feedback of the analogue outputs. Digital I/O A set of shift registers (U10, U11, U15, U16 and U17) is controlled by the IXP via the CPLD to provide digital I/O to the Facilities Connector as well as internal controls. Ethernet interface PAGE 34 TECHNICAL DESCRIPTION XFIN-BLADE-SM The IXP controls an LXT971 PHY chip (U20) that provides a 10/100 Base-T Ethernet interface. The PHY is connected to an RJ-45 socket with built-in magnetics; the socket also presents two external LEDs which are configured to indicate activity and 10/100 status. RS232 Serial Interface (DB-9) The rear of the Blade contains a standard 9-way Serial connection in order that a straight through cable may be used to connect a PC to the IXP. UART Serial Interfaces (Front Panel RJ-45) The IXP presents a serial port interface to the RJ-45 port in the front panel. 4.2.2.6 CoDec Audio received from either or both of the line ports and the PSTN interface is fed into a chain of 3x AD73322L codecs (U52, U53 and U54) that is connected to the DSP via its SPORT (Serial PORT) interface serial link. The DSP performs audio signalling to the line equipment or patches the audio to the radio module. Handset audio is fed via a codec (U53) into the DSP allowing it to be mixed to line or the radio modules under software control. Audio is also fed to the speaker on the front panel. The codec contains built-in analogue gain adjustment under software control. 4.2.2.7 Audio Interface General External audio equipment is connected to either of the two independent audio ports which are presented barriered on the RJ45 connectors, and un-barriered on the 37-way Facilities Connector. Two and Four Wire The barriered connections are link selectable as either two or four wire. In two-wire mode the balance of the hybrid can be set manually by moving LN18 (LN16 for port 2) to position 2-3. If a test tone is generated to line, the reflected audio can be monitored on TP57 (TP62 for port 2) and variable resistor R128 (R135 for port 2) can be adjusted to give the minimum level. At the time of configuration, the audio levels of the line ports must be set for optimal performance. In line-to-air mode, it must be possible for a -10dBm signal to generate a 2.5kHz (full-scale) deviation. In loopback mode, an undistorted signal up to -10dBm should be re-outputted with unity gain; this can be configured by inputting a -14.4dBm signal (equivalent to 1.5kHz/60% deviation over air) into the line port and altering the gain level until an equivalent -14.4dBm signal is seen at the output. E & M The control board contains opto-isolated digital inputs (U9, U14) and outputs (U8, U13). In order to support local connections where an external bias voltage is not present, Fuse-

TECHNICAL DESCRIPTION PAGE 37 PAGE 38 TECHNICAL DESCRIPTION XFIN-BLADE-SM 4.3 RECEIVER AND TRANSMITTER MODULES 4.3.1 Frequency Bands The Blade is supplied with a matched pair of radio sub-assemblies fitted. The designated frequency bands are:
66 - 88 MHz E0 Band 136 - 174 MHz AC Band 174 - 208 MHz K1 Band 208 - 245 MHz KM Band 310 - 350 MHz R0 Band 335 - 375 MHz R1 Band TK Band 400 - 450 MHz 400 - 480 MHz TU Band 440 - 500 MHz UW Band 470 - 530 MHz WR Band The following text refers to the components and circuits within the RF sub-assemblies only. For additional information, refer to the SRM9000 Service Manual [1]. The Rx and Tx Modules are equivalent and interchangeable for a given power classification (25W or 100W). They are connected to the Control Board via a 26-way Ribbon Cable that carries analogue audio, digital audio and control signals. Power connections are made via a 15-way, D-type connector and RF connections are made via BNC sockets. RF connections are taken to the rear of the Blade via double-
screened cables terminated with female N-types. 4.3.2 Receiver Refer to Figure 3.5. 4.3.2.1 Front-end Filters and Rx Front-end Amplifier The receiver input signal from the antenna passes through the antenna filter comprising L10, L11, L12 and associated tuning capacitors. With a transceiver module in receive mode, diodes D3, D4 and D5 in the antenna switch are reverse biased allowing the receiver input signal to be coupled through to the front-end with minimal loss. The overall insertion loss of the antenna filter and switch is approximately 0.8dB. Front-end selectivity is provided by varactor tuned bandpass filters at the input and output of the RF amplifier. Front-end tuning voltages are derived from the alignment data stored in the radio. The DSP processes this data to optimise front-end tuning relative to the programmed channel frequencies that may be changed at any time without re-aligning the radio. To achieve the required varactor tuning range an arrangement of positive and negative bias power supplies is used to provide a total bias across the varactors of up to 14.0VDC. A fixed 2.5V positive bias derived from the 5.0V supply and voltage divider R425/426 is applied to the cathodes of the varactor diodes. The negative bias supply originates at the DSP/FPGA as a composite digital tuning signal (FE TUNE) containing the data for the four front-end tuning values TUNE 1 to 4 for the particular channel frequency selected. The level is dependent on channel frequency and tuning and varies between +0.1 and
+3.0V. This signal then passes through buffer U901A and level translator Q900 to Q903 where it is converted to a high level (-0.5 to -11.5V) negative equivalent of the original signal. TECHNICAL DESCRIPTION PAGE 39 l i i i i

i i l l Figure 3.5 - VHF/UHF Receiver Block Diagram PAGE 40 TECHNICAL DESCRIPTION XFIN-BLADE-SM for single-ended The RF front-end amplifier stage comprises a low-noise transistor amplifier (Q400), which is compensated to maintain good linearity across the required frequency bands and temperature range. This provides excellent intermodulation and blocking performance across the full operating range. The gain of this stage is typically 17dB for both UHF and VHF versions. 4.3.2.2 First Mixer and IF Section The output of the last front-end bandpass filter is coupled into single balanced mixer T400/D413 which converts the RF signal to an IF frequency of 45MHz. The local oscillator injection level is typically +8dBm at T400 pin 1 with low side injection used for UHF and high side for VHF. Following the mixer is IF amplifier Q401 which provides approximately 15dB of gain and in association with its output circuitry presents the required load conditions to the 4 pole 45MHz crystal filter Z401/402. 4.3.2.3 Quadrature Demodulator Additional IF gain of approximately 30dB occurs at U401, which is a dedicated IF AGC amplifier/Quadrature, Demodulator configured input and output operation. The AGC voltage for U401 is derived from the RSSI function of the DSP via AUX CTL and multiplexer U902. The onset of AGC operation occurs when RF input signal levels at the antenna exceeds -90dBm. Conversion of the 45MHz IF signal to I and Q baseband signals is carried out by the demodulator section of U401. The 90MHz local oscillator signal is generated by VCO Q402 which is phase locked by the auxiliary PLL output of U701 via feedback signal AUX LO2. 4.3.2.4 Receiver Audio Processing All receiver audio processing and filtering functions are performed by the CODEC U800 under the control of the DSP. The receiver I and Q analogue baseband signals are converted to digital signals by the CODEC ADC before being applied to a series of digital filters which provide the final stage of adjacent channel filtering, high pass and low pass filtering and mute noise processing for narrow and wideband operation. The processed signals are then converted to analogue audio signals by the CODEC DAC and are applied to conventional audio amplifiers U803A/B and the speaker amplifier U5. The speaker circuits are not used in the Blade. The carrier and signalling mute functions are performed by Q810/811/813 under DSP control with additional receiver muting to U803B being applied by U103C when the mobile is in transmit mode. Flat audio (20Hz 5.8kHz) is provided to S1-6 via amplifier U803A. De-emphasis is performed on the Control Board. Software functions are used to filter off signals below 300Hz and above 3kHz. 4.3.3 Transmitter Refer to Figure 3.6. TECHNICAL DESCRIPTION PAGE 41 4.3.3.1 Drivers and PA Stages The RF output level from the VCO buffer Q604 is typically +5dBm (UHF) and +8dBm
(VHF). TX buffer Q606 increases this level by approximately 3dB (UHF) and 11dB (VHF) and also provides additional VCO isolation. The following section of the TX buffer Q612 is controlled by the transmitter power control loop and Q609. Q609 is normally saturated in transmit mode so there is no minimum gain control applied to this stage. The gain of Q612 is typically 10dB (UHF) and 15dB (VHF) but the output level is reduced by input and output resistive attenuators to limit the PA driver input level to typically +20dBm. The gain of PA driver Q12 is controlled by the power control loop to ensure that transmitter output power remains within defined limits. The PA driver output level is typically +25dBm. PA module U2 utilises three stages (UHF) and two stages (VHF) to achieve the required final RF output power level of +44dBm (25 watts). Power output settings are derived from alignment data stored in flash memory during the initial factory alignment. The DSP processes this data to optimise the power output level relative to the programmed channel frequencies which may be changed at any time without retuning the radio. An active filter comprising Q14, 17,18 and 19 provides isolation to minimise power supply noise at the PA. This is achieved by maintaining a voltage differential of approximately 1V across Q14 and indirectly filtering its gate voltage. Q14 is switched on only during transmit via R523 to minimise receiver power requirements.

L1, R54, a printed circuit transmission line, D6 and associated components comprise the power detector with Q3/10, U3 and associated components providing the power setting and control sections. Forward and reverse power is sampled by the power detector and applied as a DC voltage to the inverting input of comparator U3A. The TX PWR SET voltage, which is a DC voltage proportional to the programmed TX power setting, is applied to the non-
inverting input of the comparator. PA module output level changes due to supply voltage, load or temperature variations are detected and applied to the comparator which proportionally adjusts the PA driver (Q12) supply, and therefore the PA drive level, via Q10/Q3. High temperature protection is provided by Thermistor R452 which progressively reduces the power level if the PA module temperature becomes excessive, approximately 86C case temperature. Q15 and Q16 provide for dual power control time constants necessary for good power ramp and decay characteristics. 4.3.3.3 Antenna Changeover and Harmonic Filter The antenna changeover circuit consisting of pin diodes D3/D4/D5 is switched by Q4/Q8/Q11 and associated circuitry allowing the transmitter output to be coupled to the antenna while providing isolation for the receiver input. With the transmitter switched on, the diodes are forward biased allowing power to be coupled through to the antenna and isolating the receiver by grounding its input at C28. The short circuit at the receiver input is transformed to an effective open circuit at D3 by L13, which minimises transmitter loading. With the transmitter switched off the diodes are reverse biased allowing the receiver input signal to reach the receiver front-end with minimal loading and loss. The harmonic rejection low pass filter comprises L10/11/12 and associated capacitors. 4.3.3.4 Transmitter Audio Processing Microphone audio input signals of 40mV RMS, with a source impedance of 470 ohms, are provided at the microphone input (AUD IN1) by the Control Board. Pre-emphasised flat-
audio, (300Hz 3kHz; 20Hz 3kHz; or 20Hz 5.8kHz) is provided to the transmitter by the Control Board via the 26-way ribbon cable. U108 is a control gate for the microphone audio signals. AUD IN2 is the external audio options and data input used by the Blade Control Board. This is controlled by gate U107. Inverter Q20 ensures that the mic. audio is muted when the data or audio options signals are active. The AUD IN2 input level and source impedance is the same as the microphone input. Alternatively, the Blade can bypass the audio input circuits by sending a digital audio stream to the transceiver module. Q812 is a unity gain amplifier that provides buffering of the audio and data signals. U103B provides CODEC input switching which selects either the receiver I signal or transmitter audio/data signals depending on the TX/RX mode. All pre-emphasis, filtering, compression and limiting processes for narrow and wideband operation are carried out in the CODEC (U800) under the control of the DSP. The processed transmitter audio/data from the CODEC output at VOUTL is applied to the VCO as a modulation signal with a level of approximately 200mV P/P. PAGE 44 TECHNICAL DESCRIPTION 4.3.4 Frequency Synthesis XFIN-BLADE-SM 4.3.4.1 General Refer to Figure 3.7. The SRM9000 frequency synthesiser consists of individual transmitter and receiver (local oscillator) voltage controlled oscillators, loop filter, varactor negative bias generator, reference oscillator and an integrated, dual phase locked loop device U701. 4.3.4.2 PLL The PLL device contains two prescalers, programmable dividers and phase comparators to provide a main and auxiliary PLL. The main PLL of U701 controls the frequency of the TX/RX VCOs via Control Voltage outputs at pins 2 and 3 and VCO Feedback to pin 6. The auxiliary PLL is used to control the receiver 90MHz second local oscillator via the Control Voltage output at pin 17 and VCO Feedback to pin 15. The PLL operation involves the division of the 14.4MHz reference oscillator frequency by divider U710 and the internal divider of U701 down to a lower frequency which corresponds to a sub-multiple of the radio channel spacing i.e. 6.25kHz for 12.5/25kHz channel spacing or 5kHz for 20kHz channel spacing. The VCO frequency is sampled and divided down to the same frequency after which it is phase compared to the reference. Any error produces an offset to the Control Voltage output which is used to correct the VCO frequency. A valid lock detect output is derived from pin 20 and is sampled by the FPGA during transmit. If an unlocked signal is detected the radio will switch back to receive mode. 4.3.4.3 VCO The transmitter and receiver VCOs use low noise JFET transistors (Q600 RX, Q602 TX) and inductors L602 (RX), L608 (TX) to generate the signals for the required band coverage. Electronic tuning is provided by varactor diodes D600 to D608 with their control voltages derived from the Loop Filter, PLL and Negative Bias Generator. VCO selection and timing is controlled by the DSP via the RX and TX power supplies and applied through switches Q601 (RX) and Q603 (TX). VCO buffer Q604/605 isolates the VCO from load variations and active power supply filter Q615 minimises supply related noise. A PLL feedback signal is sampled from the VCO buffer output via buffer Q607. 4.3.4.4 Negative Bias Generator and Loop Filter A positive and negative varactor bias supply similar to the front-end varactor arrangement has been used to achieve the required broadband tuning range of the VCOs. PLL device U701 is programmed to deliver a fixed nominal +2.5V output from phase detector/charge pump CPPF or CPP (selection depends on radio setup) regardless of the channel frequency selected. This voltage is filtered to remove synthesiser noise and reference products by loop filter C719/722/734 and R721/724/734. The resulting low noise voltage is applied to the cathode side of the VCO varactor tuning diodes as a positive bias voltage. The negative bias supply originates as a positive DC voltage (0.1V to 3.0V) at the DAC output of U701 (DOUT) with a level relative to the programmed state of the radio (e.g. TECHNICAL DESCRIPTION PAGE 45 channel frequency, TX/RX state). The voltage is converted to a high level negative supply by VCO Varicap Negative Supply Q700 to Q703. The -17V rail of this supply is generated by U300B/C with D304 to D307 providing the voltage multiplying effect needed to achieve
-17V. The output of the negative supply is applied directly to the VCO varactor anodes as the negative tuning voltage VCAP BIAS. 4.3.4.5 Phase Modulator The modulation path for audio, data and higher frequency CTCSS signals is via D609 and its associated components in the TX VCO. The reference input to the PLL (FXTAL) provides the low frequency modulation path in conjunction with phase modulator Q714 to Q716. U711A is a low pass filter that provides 6dB per octave attenuation to frequencies above approximately 180Hz. Modulation balance adjustment is carried out using a CODEC generated 100Hz square wave applied to TX MOD1. A DAC output from the Alignment Tool is applied to buffer U711B and ramp generator Q711 to Q713 via the TUNE BAL line to adjust the low frequency modulation level. 4.3.4.6 Reference Oscillator TCXO U700 determines the overall frequency stability and frequency setting of the radio. The frequency setting is achieved by adjusting its ADJ voltage with the Alignment Tool. In addition, the ADJ input is used in a frequency control loop with the receiver I and Q signals to provide receiver AFC. U700 operates at 14.4MHz and is specified at 2.0ppm frequency stability over the temperature range 25C to +75C.

(U106) combination which together with a number of other dedicated devices perform all the operational and processing functions required by the radio. The FPGA is configured by the DSP under software control to provide the following functions:
Channel set-up for operating frequency Modulation processing and filtering De-modulation processing and filtering TX power output reference Receiver front-end tuning Serial communications with control board Modem functionality for data modulation Embedded signalling / CTCSS generation and decoding CO control Receiver muting control TX / RX switching PLL detect 4.3.5.2 DSP Clock Oscillator The DSP is clocked by a 15.360MHz oscillator that consists of crystal X100 and an internal DSP oscillator. Q100 forms a crystal switching circuit with C117 which when activated by a command from the FPGA steers the oscillator away from potential interfering frequencies. 4.3.6 RF Sub-Assembly Internal Memory Memory consists of the internal DSP memory and an external 4MB non-volatile Flash Memory U104. When power is off, program and data is retained in Flash Memory. At power-on, a boot program downloads the DSPs program from Flash Memory to its internal RAM for faster program execution and access to data. 4.3.6.1 Multiplexer U902 contains 2 separate 4-channel multiplexers providing a total of 8 independently controlled analogue switches. Under software control, the multiplexers produce tuning voltages from supplied data for the receiver front-end (TUNE 1 to 4), TX power setting
(TX PWR SET), receiver AGC (AGC-1), alert tone (A TONE) and FPGA ramp generator
(ADC REF). Buffer U802B is fed with a composite digital tuning signal (AUX CTL) from the DSP/FPGA containing the data for AGC, A TONE, ADC REF and TX PWR SET settings. The level is dependent on channel frequency and tuning and varies between 0.1 to 3.0V. This signal TECHNICAL DESCRIPTION PAGE 49 is applied to one group of 4 analogue switches in U902 via a common input connected to pin 13. The second group of 4 switches is fed with the receiver front-end tuning signal FE TUNE (to provide outputs for TUNE 1 to 4) via the second common input at pin 3 as described in the receiver front-end section. The 2 groups of analogue switches are independently controlled by FPGA binary signals MUX A0 and A1 and enable line MUXEN to output the required tuning voltages as a series of pulses. These pulses are converted to steady state voltages by integration capacitors C904 to 911 and C921 to 925. 4.3.7 RF Sub-Assembly Internal Power Supplies 4.3.7.1 Power On Function This set of functionality is designed for normal use in a vehicle environment; hence much of it is unused in this product. The unregulated 13.8V DC input is routed directly to high current devices and is also switched via FET Q350. The output from Q350 feeds three, low drop out series regulators and associated switched and auxiliary supplies that along with a negative voltage generator provide all the switched power requirements of the transceiver. Q315/316/317 and U313 form a power on/off latch circuit that is activated by a pulse from the control unit or microphone/handset via PWR ON or PWR OFF and controls the FET power switch Q350. A PWR OFF operation requires the button to be held down for more than 2 seconds. This is then sensed by the FPGA via the PWR SENSE line that turns the radio off by placing a positive pulse on the PWR OFF line thereby resetting U313B. 4.3.7.2 Power Lines The following is a list of the internal RF Sub-Assemblys power supplies and some of the devices and circuits they supply.

These should be tested, by use of a suitable test set, e.g. Anritsu/Wiltron S331A, for good VSWR (1.5:1 or better) at the Tx and Rx frequencies prior to use. Mating connectors should be galvanically compatible with nickel outer and gold centre pin to minimise passive intermodulation. A minimum of 85dB transmit-receive isolation should be provided by the antenna system and associated filters. 4.5 POWER SUPPLIES For type approval reasons, this product should not be operated with un-approved supplies. The switch mode supplies used in the wall mount and rack mount ancillaries are able to accept main AC in the range of 100 to 240 V, 50 or 60Hz. The output from the switched mode power supply to the Blade is +13.6VDC. Pin 3 on the D-type Power Connector provides protective earthing on the equipment. This should be connected using heavy duty Green/Yellow earthing wire, capacity greater than mains feed to equipment, as few bends as possible and an appropriate eyelet tag. Mains protective Earth should be checked for low impedance (<0.3W). The equipment must be installed so that the IEC connector for the Wall or Rack Mount can be easily removed and/or the power socket should be readily accessible. All mains wiring must comply with local wiring regulations. 4.6 CONFIGURATION Configuration is provided via file download. This is performed via the XBMT Programmer using a PC connected to the Xfin Control card via its Ethernet port. Files are then stored in the product in non-volatile memory. Editing of parameters on a live base station is also possible with a connected PC. 4.7 ADJUSTMENT AND ALIGNMENT The two RF modules within this product are based upon the RF card of an SRM9000 mobile. The set up and alignment procedures for SRM9000 should be followed. In the event of a level-3 repair being required, refer to the SRM9000 Service Manual (TSD-
SRM9000-SM) [1]. There are no user adjustments to be made in normal use.

Test report is as follows:
As per Section 1.1310 and Section 2.1091 certification of this transmitter is sought using the Controlled / Occupational exposure limits as detailed in OST/OET Bulletin Number 65 as a power of 100 watts is to be used in a fixed environment. Calculations have been made using the General Public/Uncontrolled Exposure limits. Minimum safe distances have been calculated below. Power density, W/m2 = E2/3770
- Occupational / Controlled Exposure limit will be 1.46 mW/cm2
(f/300 = 440 MHz/300)
- General Population / Uncontrolled exposure limit will be 0.29 mW/cm2
(f/1500 = 440 MHz/1500) The minimum distance from the antenna at which the MPE is met is calculated from the equation relating field strength in V/m, transmit power in watts, transmit antenna gain, transmitter duty cycle and separation distance in metres:
E, V/m = ( (30 * P * G)) / d Controlled Uncontrolled E = 1.46 mW/cm2 = E2/3770 E = 0.29 mW/cm2 = E2/3770 E= 1.46*3770 E= 0.29*3770 E = 74.2 V/m E = 33.1 V/m The rated maximum transmitter power = 100.0 watts. Transmitter operated using a quarter wave whip antenna with a gain of 2.15 dBi (1.64). Controlled Uncontrolled d = (30 * P * G*DC) / E d = (30 * 100.0 * 1.64) / 74.2 d = (30 * 25.0 * 1.64) / 33.1 d = 0.94 metres or 94 cm d = 2.11 metres or 211 cm Result: Complies RADIO FREQUENCY HAZARD INFORMATION PAGE 79

Brief Description: The Xfin Blade is a 1U trunking system with an integrated basestation and the capability to provide a control and/or traffic channel. It incorporates the established MPT1327 trunking standard with next generation hardware and VoIP technology. A trunked site consists of a number of Blade units which are inter-connected using standard CAT5 Ethernet cable. PAGE 8 INTRODUCTION XFIN-BLADE-SM 2 PRODUCT CODES The following information is displayed on the Type Approval Label located on the chassis behind the speaker housing. 2.1 SERIAL NUMBER The product serial number is broken down as follows:

Digits 1-3 4-5 Hardware configuration; XBI = Xfin 25W internal PSU, XB0 = Xfin 25W external PSU, XBP = Power Blade 100W Tx & Rx frequency band designation (alphanumeric) 2.1.2 MAC Address Each Blade is assigned a unique 12-character alphanumeric MAC address. 2.1.3 Modification State Where changes are made to hardware or software between major releases, this will be recorded on the Mod State tick-boxes (A D) on the Type Approval Label. PRODUCT CODES PAGE 9 Receiver Transmitter Control Board removed High-power Amplifier or Integrated PSU Option Figure 3.1 - Layout of the Blade with the top lid 3 DESCRIPTION The Blade is a 1U high by 19 wide rack-mountable unit containing two SRM9000 sub-assemblies, a control card, and a fan bulkhead which mates with the angled front panel and MMI card. There is also provision for fitting a high power amplifier or integrated power supply option. 3.1 VENTILATION In order to provide full-power continuous operation in any orientation and in a 1U envelope, the Blade uses forced air-cooling. A pair of fans draws air in from an air intake located underneath the front lip of the angled front panel. This air is compressed by a baffle that directs the airflow underneath the heatsink of the SRM9000 sub assemblies. A second pair of fans is used for the high-power amplifier option if fitted. Fans are located to maximise the cooling for the transmitting module. Air is exhausted through a grilled area on the rear panel immediately below the electrical connectors. Vent holes in the internal baffle allow a small amount of air to bleed diagonally through the top section of the chassis to ensure that hot spots do not form on the component side of the sub-assemblies. The fans are mounted in a bulkhead located immediately behind the front panel. The front panel, MMI board and fan bulkhead are separately assembled and removed from the unit as sub-assemblies. The fans, loudspeaker and indicator LEDs are all controlled from the MMI PCB that fits into this sub-assembly. The fans are not only speed controlled to minimise noise and wear, but their speed is also monitored to provide early warning of failure. In normal operation, the fans are turned on to full speed to minimise any possibility of a stall, the speed is then turned down based upon equipment temperature. Even if the temperature is very low, fans are always kept running at a low speed. Temperature is sensed from a Thermistor located on the underside of the control board. This Thermistor protrudes into the airflow from the transmit PA module. When installing the Blade it is important to ensure that adequate ventilation is provided for each base station unit. A minimum free-area of 72cm2 is recommended per base station at the inlet AND at the outlet. This should be increased if air has to be drawn through ducts or has to be deflected around corners. Noise and dust build up can be reduced by keeping cabling and other obstructions out of the main airflows. There are no dust filters fitted in this product. If it is to be used in very dirty environments, then additional steps should be taken to prevent ingress of dust as this will affect thermal performance. Filters should only be used in external cabinets if they can be regularly maintained. 3.2 SRM9000 SUB-ASSEMBLY The RF performance of this product is derived from a pair of SRM9000 RF PCBs mounted on a Heatsink sub-assembly that is designed to permit continuous operation at full power. The sub-assembly also provides RF screening, so it is important that it is accurately assembled and reassembled. The sub-assembly has a plate attached to the rear edge with two quarter-turn fasteners for rapid removal. The unit is retained in the Blade chassis by the front edge of the Heatsink that inserts underneath the fan baffle, the rear of the subassembly is held in place by the quick release fasteners. These units are electrically identical to SRM9000 and are also fully interchangeable in the 25W power group (the Transmit module is different for the 100W systems). Control is provided via the 26-way ribbon connector. Power is supplied via the DB-15 connector and RF signals are coupled to the BNC sockets with double-screened cables. 3.3 SPECIFICATIONS 3.3.1 General Channel Bandwidth Modulation 12.5kHz (11K0F3EJN), 20kHz (14K0F3EJN) or 25kHz (16K0F3EJN) selectable per channel Freq.

The DSP is responsible for all audio processing including mixing, FFSK encoding/decoding, DTMF encoding/decoding, supervisory tone generation, audio emphasis and speech processing for VOIP between Blades. Booting The DSP downloads the application code from the IXP Network Processor at start up and runs the software entirely in internal memory. RS232 Serial Interface (Rear RJ-45) The rear of the Blade contains a standard RJ-45 Serial connection in order that an engineer may connect a PC to the DSP via an RJ-45 to DB-9 cable. Debug commands may then be issued to the DSP for diagnostic information. CPLD Interface Communications between the IXP Network Processor and the DSP are performed by connecting the data bus on the IXP to the host interface (Lattice LC256V-75T100 CPLD) connecting to the DSP. The IXP writes to the host interface, triggering a DMA on the DSP to copy the data to a buffer. After a packet has been sent, the DMA on the DSP copies data from an outgoing buffer to the host interface port that is read by the IXP. This enables high-speed communications without impacting the performance of the DSP. PAGE 30 TECHNICAL DESCRIPTION XFIN-BLADE-SM 4.2.2.4 Power The control board requires a 12V 2000ma supply. Linear regulators are provided to reduce the input voltage down to 10V and 5V for the audio circuits. The input voltage supply is also regulated down to 3.3V for the digital logic via a switched mode power supply. The 1.3V supply for the IXP processor core is generated by a regulator off the 3.3V rail. The 1.2V supply for the DSP core is generated by a diode (controlled by the DSP) off the 3.3V rail. 4.2.2.5 IXP Description The main processor is an IXP42x processor manufactured by INTEL. It consists of a central ARM based processor supported by separate network processor engines for supporting the Ethernet and USB ports. The IXP runs the application code under MontaVista Linux. The application code consists of Trunked Site Control, Inter-Blade Communications, Site Configuration, Fan Control and the LCD menu system. The network processor also provides support to the DSP. The IXP is connected to external flash memory that stores the IXP software. Reset of the IXP is performed reset circuitry monitoring voltage supplies. Watchdog The IXP processor has its own internal watchdog. Fan Control The IXP performs fan control via Maxim Fan Regulator devices, monitoring the temperature of the airflow from the transmitter module using a thermistor (RT1). If the temperature is too high or low, the speed of the fans is adjusted accordingly. Fans are not allowed to stop during normal operation. Each fan generates a tachometer output allowing software to detect a fan failure or potential failure by monitoring fan speed. If one fan fails the speed of the second fan will be increased to compensate. Analogue Outputs Two analogue outputs are provided by a dual-channel Digital to Analogue Converter
(U41). They provide analogue outputs to the Facilities Connector to output, for example, the RSSI level. Analogue Inputs The ADC (U56) has eight analogue inputs available, which are currently used to provide voltage monitoring of the thermistor and the 12V unregulated supply, receive inputs from the PA header and provide feedback of the analogue outputs. Digital I/O A set of shift registers (U10, U11, U15, U16 and U17) is controlled by the IXP via the CPLD to provide digital I/O to the Facilities Connector as well as internal controls. Ethernet interface TECHNICAL DESCRIPTION PAGE 31 The IXP controls an LXT971 PHY chip (U20) that provides a 10/100 Base-T Ethernet interface. The PHY is connected to an RJ-45 socket with built-in magnetics; the socket also presents two external LEDs which are configured to indicate activity and 10/100 status. RS232 Serial Interface (DB-9) The rear of the Blade contains a standard 9-way Serial connection in order that a straight through cable may be used to connect a PC to the IXP. UART Serial Interfaces (Front Panel RJ-45) The IXP presents a serial port interface to the RJ-45 port in the front panel. 4.2.2.6 CoDec Audio received from either or both of the line ports and the PSTN interface is fed into a chain of 3x AD73322L codecs (U52, U53 and U54) that is connected to the DSP via its SPORT (Serial PORT) interface serial link. The DSP performs audio signalling to the line equipment or patches the audio to the radio module. Handset audio is fed via a codec (U53) into the DSP allowing it to be mixed to line or the radio modules under software control. Audio is also fed to the speaker on the front panel. The codec contains built-in analogue gain adjustment under software control. 4.2.2.7 Audio Interface General External audio equipment is connected to either of the two independent audio ports which are presented barriered on the RJ45 connectors, and un-barriered on the 37-way Facilities Connector. Two and Four Wire The barriered connections are link selectable as either two or four wire. In two-wire mode the balance of the hybrid can be set manually by moving LN18 (LN16 for port 2) to position 2-3. If a test tone is generated to line, the reflected audio can be monitored on TP57 (TP62 for port 2) and variable resistor R128 (R135 for port 2) can be adjusted to give the minimum level. At the time of configuration, the audio levels of the line ports must be set for optimal performance. In line-to-air mode, it must be possible for a -10dBm signal to generate a 2.5kHz (full-scale) deviation. In loopback mode, an undistorted signal up to -10dBm should be re-outputted with unity gain; this can be configured by inputting a -14.4dBm signal
(equivalent to 1.5kHz/60% deviation over air) into the line port and altering the gain level until an equivalent -14.4dBm signal is seen at the output. E & M The control board contains opto-isolated digital inputs (U9, U14) and outputs (U8, U13). In order to support local connections where an external bias voltage is not present, Fuse-

PAGE 34 TECHNICAL DESCRIPTION XFIN-BLADE-SM TECHNICAL DESCRIPTION PAGE 35 4.3 RECEIVER AND TRANSMITTER MODULES 4.3.1 Frequency Bands The Blade is supplied with a matched pair of radio sub-assemblies fitted. The designated frequency bands are:
66 - 88 MHz E0 Band 136 - 174 MHz AC Band 174 - 208 MHz K1 Band 208 - 245 MHz KM Band 310 - 350 MHz R0 Band 335 - 375 MHz R1 Band 400 - 450 MHz TK Band 400 - 480 MHz TU Band 440 - 500 MHz UW Band 470 - 530 MHz WR Band The following text refers to the components and circuits within the RF sub-assemblies only. For additional information, refer to the SRM9000 Service Manual [1]. The Rx and Tx Modules are equivalent and interchangeable for a given power classification (25W or 100W). They are connected to the Control Board via a 26-way Ribbon Cable that carries analogue audio, digital audio and control signals. Power connections are made via a 15-way, D-type connector and RF connections are made via BNC sockets. RF connections are taken to the rear of the Blade via double-
screened cables terminated with female N-types. 4.3.2 Receiver Refer to Figure 3.5. 4.3.2.1 Front-end Filters and Rx Front-end Amplifier The receiver input signal from the antenna passes through the antenna filter comprising L10, L11, L12 and associated tuning capacitors. With a transceiver module in receive mode, diodes D3, D4 and D5 in the antenna switch are reverse biased allowing the receiver input signal to be coupled through to the front-end with minimal loss. The overall insertion loss of the antenna filter and switch is approximately 0.8dB. Front-end selectivity is provided by varactor tuned bandpass filters at the input and output of the RF amplifier. Front-end tuning voltages are derived from the alignment data stored in the radio. The DSP processes this data to optimise front-end tuning relative to the programmed channel frequencies that may be changed at any time without re-aligning the radio. To achieve the required varactor tuning range an arrangement of positive and negative bias power supplies is used to provide a total bias across the varactors of up to 14.0VDC. A fixed 2.5V positive bias derived from the 5.0V supply and voltage divider R425/426 is applied to the cathodes of the varactor diodes. The negative bias supply originates at the DSP/FPGA as a composite digital tuning signal (FE TUNE) containing the data for the four front-end tuning values TUNE 1 to 4 for the particular channel frequency selected. The level is dependent on channel frequency and tuning and varies between +0.1 and +3.0V. This signal then passes through buffer U901A and level translator Q900 to Q903 where it is converted to a high level (-0.5 to -11.5V) negative equivalent of the original signal.

i i l l Figure 3.5 - VHF/UHF Receiver Block Diagram TECHNICAL DESCRIPTION PAGE 37 The RF front-end amplifier stage comprises a low-noise transistor amplifier (Q400), which is compensated to maintain good linearity across the required frequency bands and temperature range. This provides excellent intermodulation and blocking performance across the full operating range. The gain of this stage is typically 17dB for both UHF and VHF versions. 4.3.2.2 First Mixer and IF Section The output of the last front-end bandpass filter is coupled into single balanced mixer T400/D413 which converts the RF signal to an IF frequency of 45MHz. The local oscillator injection level is typically +8dBm at T400 pin 1 with low side injection used for UHF and high side for VHF. Following the mixer is IF amplifier Q401 which provides approximately 15dB of gain and in association with its output circuitry presents the required load conditions to the 4 pole 45MHz crystal filter Z401/402. 4.3.2.3 Quadrature Demodulator Additional IF gain of approximately 30dB occurs at U401, which is a dedicated IF AGC amplifier/Quadrature, Demodulator configured for single-ended input and output operation. The AGC voltage for U401 is derived from the RSSI function of the DSP via AUX CTL and multiplexer U902. The onset of AGC operation occurs when RF input signal levels at the antenna exceeds -90dBm. Conversion of the 45MHz IF signal to I and Q baseband signals is carried out by the demodulator section of U401. The 90MHz local oscillator signal is generated by VCO Q402 which is phase locked by the auxiliary PLL output of U701 via feedback signal AUX LO2. 4.3.2.4 Receiver Audio Processing All receiver audio processing and filtering functions are performed by the CODEC U800 under the control of the DSP. The receiver I and Q analogue baseband signals are converted to digital signals by the CODEC ADC before being applied to a series of digital filters which provide the final stage of adjacent channel filtering, high pass and low pass filtering and mute noise processing for narrow and wideband operation. The processed signals are then converted to analogue audio signals by the CODEC DAC and are applied to conventional audio amplifiers U803A/B and the speaker amplifier U5. The speaker circuits are not used in the Blade. The carrier and signalling mute functions are performed by Q810/811/813 under DSP control with additional receiver muting to U803B being applied by U103C when the mobile is in transmit mode. Flat audio (20Hz 5.8kHz) is provided to S1-6 via amplifier U803A. De-emphasis is performed on the Control Board. Software functions are used to filter off signals below 300Hz and above 3kHz. 4.3.3 Transmitter Refer to Figure 3.6. PAGE 38 TECHNICAL DESCRIPTION XFIN-BLADE-SM 4.3.3.1 Drivers and PA Stages The RF output level from the VCO buffer Q604 is typically +5dBm (UHF) and +8dBm
(VHF). TX buffer Q606 increases this level by approximately 3dB (UHF) and 11dB (VHF) and also provides additional VCO isolation. The following section of the TX buffer Q612 is controlled by the transmitter power control loop and Q609. Q609 is normally saturated in transmit mode so there is no minimum gain control applied to this stage. The gain of Q612 is typically 10dB (UHF) and 15dB (VHF) but the output level is reduced by input and output resistive attenuators to limit the PA driver input level to typically +20dBm. The gain of PA driver Q12 is controlled by the power control loop to ensure that transmitter output power remains within defined limits. The PA driver output level is typically +25dBm. PA module U2 utilises three stages (UHF) and two stages (VHF) to achieve the required final RF output power level of +44dBm (25 watts). Power output settings are derived from alignment data stored in flash memory during the initial factory alignment. The DSP processes this data to optimise the power output level relative to the programmed channel frequencies which may be changed at any time without retuning the radio. An active filter comprising Q14, 17,18 and 19 provides isolation to minimise power supply noise at the PA. This is achieved by maintaining a voltage differential of approximately 1V across Q14 and indirectly filtering its gate voltage. Q14 is switched on only during transmit via R523 to minimise receiver power requirements.

Figure 3.6 - VHF/UHF Transmitter Block Diagram PAGE 40 TECHNICAL DESCRIPTION XFIN-BLADE-SM 4.3.3.2 Tx Power Control Output power is stabilised by a power control feedback loop. L1, R54, a printed circuit transmission line, D6 and associated components comprise the power detector with Q3/10, U3 and associated components providing the power setting and control sections. Forward and reverse power is sampled by the power detector and applied as a DC voltage to the inverting input of comparator U3A. The TX PWR SET voltage, which is a DC voltage proportional to the programmed TX power setting, is applied to the non-inverting input of the comparator. PA module output level changes due to supply voltage, load or temperature variations are detected and applied to the comparator which proportionally adjusts the PA driver (Q12) supply, and therefore the PA drive level, via Q10/Q3. High temperature protection is provided by Thermistor R452 which progressively reduces the power level if the PA module temperature becomes excessive, approximately 86C case temperature. Q15 and Q16 provide for dual power control time constants necessary for good power ramp and decay characteristics. 4.3.3.3 Antenna Changeover and Harmonic Filter The antenna changeover circuit consisting of pin diodes D3/D4/D5 is switched by Q4/Q8/Q11 and associated circuitry allowing the transmitter output to be coupled to the antenna while providing isolation for the receiver input. With the transmitter switched on, the diodes are forward biased allowing power to be coupled through to the antenna and isolating the receiver by grounding its input at C28. The short circuit at the receiver input is transformed to an effective open circuit at D3 by L13, which minimises transmitter loading. With the transmitter switched off the diodes are reverse biased allowing the receiver input signal to reach the receiver front-end with minimal loading and loss. The harmonic rejection low pass filter comprises L10/11/12 and associated capacitors. 4.3.3.4 Transmitter Audio Processing Microphone audio input signals of 40mV RMS, with a source impedance of 470 ohms, are provided at the microphone input (AUD IN1) by the Control Board. Pre-emphasised flat-
audio, (300Hz 3kHz; 20Hz 3kHz; or 20Hz 5.8kHz) is provided to the transmitter by the Control Board via the 26-way ribbon cable. U108 is a control gate for the microphone audio signals. AUD IN2 is the external audio options and data input used by the Blade Control Board. This is controlled by gate U107. Inverter Q20 ensures that the mic. audio is muted when the data or audio options signals are active. The AUD IN2 input level and source impedance is the same as the microphone input. Alternatively, the Blade can bypass the audio input circuits by sending a digital audio stream to the transceiver module. Q812 is a unity gain amplifier that provides buffering of the audio and data signals. U103B provides CODEC input switching which selects either the receiver I signal or transmitter audio/data signals depending on filtering, compression and limiting processes for narrow and wideband operation are carried out in the CODEC (U800) under the control of the DSP. The processed transmitter audio/data from the CODEC output at VOUTL is applied to the VCO as a modulation signal with a level of approximately 200mV P/P. All pre-emphasis, the TX/RX mode. TECHNICAL DESCRIPTION PAGE 41 4.3.4 Frequency Synthesis 4.3.4.1 General Refer to Figure 3.7. The SRM9000 frequency synthesiser consists of individual transmitter and receiver (local oscillator) voltage controlled oscillators, loop filter, varactor negative bias generator, reference oscillator and an integrated, dual phase locked loop device U701. 4.3.4.2 PLL The PLL device contains two prescalers, programmable dividers and phase comparators to provide a main and auxiliary PLL. The main PLL of U701 controls the frequency of the TX/RX VCOs via Control Voltage outputs at pins 2 and 3 and VCO Feedback to pin 6. The auxiliary PLL is used to control the receiver 90MHz second local oscillator via the Control Voltage output at pin 17 and VCO Feedback to pin 15. The PLL operation involves the division of the 14.4MHz reference oscillator frequency by divider U710 and the internal divider of U701 down to a lower frequency which corresponds to a sub-multiple of the radio channel spacing i.e. 6.25kHz for 12.5/25kHz channel spacing or 5kHz for 20kHz channel spacing. The VCO frequency is sampled and divided down to the same frequency after which it is phase compared to the reference. Any error produces an offset to the Control Voltage output which is used to correct the VCO frequency. A valid lock detect output is derived from pin 20 and is sampled by the FPGA during transmit. If an unlocked signal is detected the radio will switch back to receive mode. 4.3.4.3 VCO The transmitter and receiver VCOs use low noise JFET transistors (Q600 RX, Q602 TX) and inductors L602 (RX), L608 (TX) to generate the signals for the required band coverage. Electronic tuning is provided by varactor diodes D600 to D608 with their control voltages derived from the Loop Filter, PLL and Negative Bias Generator. VCO selection and timing is controlled by the DSP via the RX and TX power supplies and applied through switches Q601 (RX) and Q603 (TX). VCO buffer Q604/605 isolates the VCO from load variations and active power supply filter Q615 minimises supply related noise. A PLL feedback signal is sampled from the VCO buffer output via buffer Q607. 4.3.4.4 Negative Bias Generator and Loop Filter A positive and negative varactor bias supply similar to the front-end varactor arrangement has been used to achieve the required broadband tuning range of the VCOs. PLL device U701 is programmed to deliver a fixed nominal +2.5V output from phase detector/charge pump CPPF or CPP (selection depends on radio setup) regardless of the channel frequency selected. This voltage is filtered to remove synthesiser noise and reference products by loop filter C719/722/734 and R721/724/734. The resulting low noise voltage is applied to the cathode side of the VCO varactor tuning diodes as a positive bias voltage. The negative bias supply originates as a positive DC voltage (0.1V to 3.0V) at the DAC output of U701 (DOUT) with a level relative to the programmed state of the radio (e.g. channel frequency, TX/RX state). The voltage is converted to a high level negative supply by VCO Varicap Negative Supply Q700 to Q703. The -17V rail of this supply is generated PAGE 42 TECHNICAL DESCRIPTION XFIN-BLADE-SM by U300B/C with D304 to D307 providing the voltage multiplying effect needed to achieve
-17V. The output of the negative supply is applied directly to the VCO varactor anodes as the negative tuning voltage VCAP BIAS. 4.3.4.5 Phase Modulator The modulation path for audio, data and higher frequency CTCSS signals is via D609 and its associated components in the TX VCO. The reference input to the PLL (FXTAL) provides the low frequency modulation path in conjunction with phase modulator Q714 to Q716. U711A is a low pass filter that provides 6dB per octave attenuation to frequencies above approximately 180Hz. Modulation balance adjustment is carried out using a CODEC generated 100Hz square wave applied to TX MOD1. A DAC output from the Alignment Tool is applied to buffer U711B and ramp generator Q711 to Q713 via the TUNE BAL line to adjust the low frequency modulation level. 4.3.4.6 Reference Oscillator TCXO U700 determines the overall frequency stability and frequency setting of the radio. The frequency setting is achieved by adjusting its ADJ voltage with the Alignment Tool. In addition, the ADJ input is used in a frequency control loop with the receiver I and Q signals to provide receiver AFC. U700 operates at 14.4MHz and is specified at 2.0ppm frequency stability over the temperature range 25C to +75C.

(U106) combination which together with a number of other dedicated devices perform all the operational and processing functions required by the radio. The FPGA is configured by the DSP under software control to provide the following functions:
Channel set-up for operating frequency Modulation processing and filtering De-modulation processing and filtering TX power output reference Receiver front-end tuning Serial communications with control board Modem functionality for data modulation Embedded signalling / CTCSS generation and decoding CO control Receiver muting control TX / RX switching PLL detect 4.3.5.2 DSP Clock Oscillator The DSP is clocked by a 15.360MHz oscillator that consists of crystal X100 and an internal DSP oscillator. Q100 forms a crystal switching circuit with C117 which when activated by a command from the FPGA steers the oscillator away from potential interfering frequencies. 4.3.6 RF Sub-Assembly Internal Memory Memory consists of the internal DSP memory and an external 4MB non-volatile Flash Memory U104. When power is off, program and data is retained in Flash Memory. At power-on, a boot program downloads the DSPs program from Flash Memory to its internal RAM for faster program execution and access to data. 4.3.6.1 Multiplexer U902 contains 2 separate 4-channel multiplexers providing a total of 8 independently controlled analogue switches. Under software control, the multiplexers produce tuning voltages from supplied data for the receiver front-end (TUNE 1 to 4), TX power setting (TX PWR SET), receiver AGC (AGC-1), alert tone (A TONE) and FPGA ramp generator (ADC REF). Buffer U802B is fed with a composite digital tuning signal (AUX CTL) from the DSP/FPGA containing the data for AGC, A TONE, ADC REF and TX PWR SET settings. The level is dependent on channel frequency and tuning and varies between 0.1 to 3.0V. This signal is applied to one group of 4 analogue switches in U902 via a common input connected to pin 13. The second group of 4 switches is fed with the receiver front-end tuning signal FE TUNE (to provide outputs for TUNE 1 to 4) via the second common input at pin 3 as described in the receiver front-end section. PAGE 46 TECHNICAL DESCRIPTION XFIN-BLADE-SM The 2 groups of analogue switches are independently controlled by FPGA binary signals MUX A0 and A1 and enable line MUXEN to output the required tuning voltages as a series of pulses. These pulses are converted to steady state voltages by integration capacitors C904 to 911 and C921 to 925. 4.3.7 RF Sub-Assembly Internal Power Supplies 4.3.7.1 Power On Function This set of functionality is designed for normal use in a vehicle environment; hence much of it is unused in this product. The unregulated 13.8V DC input is routed directly to high current devices and is also switched via FET Q350. The output from Q350 feeds three, low drop out series regulators and associated switched and auxiliary supplies that along with a negative voltage generator provide all the switched power requirements of the transceiver. Q315/316/317 and U313 form a power on/off latch circuit that is activated by a pulse from the control unit or microphone/handset via PWR ON or PWR OFF and controls the FET power switch Q350. A PWR OFF operation requires the button to be held down for more than 2 seconds. This is then sensed by the FPGA via the PWR SENSE line that turns the radio off by placing a positive pulse on the PWR OFF line thereby resetting U313B. 4.3.7.2 Power Lines The following is a list of the internal RF Sub-Assemblys power supplies and some of the devices and circuits they supply.

These should be tested, by use of a suitable test set, e.g. Anritsu/Wiltron S331A, for good VSWR (1.5:1 or better) at the Tx and Rx frequencies prior to use. Mating connectors should be galvanically compatible with nickel outer and gold centre pin to minimise passive intermodulation. A minimum of 85dB transmit-receive isolation should be provided by the antenna system and associated filters. 4.5 POWER SUPPLIES For type approval reasons, this product should not be operated with un-approved supplies. The switch mode supplies used in the wall mount and rack mount ancillaries are able to accept main AC in the range of 100 to 240 V, 50 or 60Hz. The output from the switched mode power supply to the Blade is +13.6VDC. Pin 3 on the D-type Power Connector provides protective earthing on the equipment. This should be connected using heavy duty Green/Yellow earthing wire, capacity greater than mains feed to equipment, as few bends as possible and an appropriate eyelet tag. Mains protective Earth should be checked for low impedance (<0.3). The equipment must be installed so that the IEC connector for the Wall or Rack Mount can be easily removed and/or the power socket should be readily accessible. All mains wiring must comply with local wiring regulations. 4.6 CONFIGURATION Configuration is provided via file download. This is performed via the XBMT Programmer using a PC connected to the Xfin Control card via its Ethernet port. Files are then stored in the product in non-volatile memory. Editing of parameters on a live base station is also possible with a connected PC. 4.7 ADJUSTMENT AND ALIGNMENT The two RF modules within this product are based upon the RF card of an SRM9000 mobile. The set up and alignment procedures for SRM9000 should be followed. In the event of a level-3 repair being required, refer to the SRM9000 Service Manual (TSD-
SRM9000-SM) [1]. There are no user adjustments to be made in normal use.
