The output power capability is 20 to 100W. The PA comprises a broad band, two stage drive amplifier whose output is split to drive four separate output stages. The outputs from these final stages are then recombined and filtered before being fed to the output socket. This type of balanced output stage offers two advantages over single ended types:

improved intermodulation performance in the presence of high signal levels from adjacent transmitters;

enhanced reliability: if one of the four output stages fails, the transmitter can still produce half its rated power. VSWR and thermal protection is incorporated into the basic design, while monitoring and alarm signals are available for both forward and reverse power. The output power is adjustable from the front panel. The main PCB is mounted directly on a die-cast chassis/heatsink. For long-term relia-

bility, four high quality, low loss Teflon PCBs are sweated to the main PCB in areas of high RF current. Extensive use is also made of the latest surface mount technology. Forced air cooling for the heatsink is provided on the T889 by a fan, which is activated whenever the transmitter is keyed. Thermal sensors will also activate the fan automati-

cally if the internal temperature reaches an unacceptable level. The T889 has a width of 120mm, occupying a double module in a Tait rack shelf

(T99-770) which will accommodate up to seven standard modules to give an attractive and convenient installation.

The final stage is composed of four transistors (Q3, Q4, Q5 & Q6) whose outputs are combined to provide the rated output power. The configuration of each of the main circuit blocks may be seen on a functional level in Figure 2.1. 2.2 RF Circuitry The driver stage of the T889 consists of a two stage transistor amplifier (Q1, Q2) which delivers a minimum of 40W. This signal is split via three 3dB couplers (L13, L14 & L15) and used to drive the four final amplifiers (Q3, Q4, Q5 & Q6). These outputs are recom-

bined by L40, L41 & L42 and passed to the antenna socket via the directional coupler and low pass filter. The directional coupler senses forward and reflected power, which is rectified (D1, D2) and passed to the control circuitry for metering, alarm and power control purposes. Power control is via a series pass transistor (Q16), which controls the supply voltage on the collector of the driver transistor (Q1). Copyright TEL 02/10/95 2.4 2.3 Circuit Operation Control Circuitry M889-00 REF Figure 2.2 Control Circuitry Block Diagram 02/10/95 Copyright TEL M889-00 Circuit Operation 2.5 2.3.1 Power Control The DC voltages from the directional coupler representing forward and reflected power are buffered by the two voltage followers, IC3 pins 1, 2 & 3 and pins 5, 6 & 7. Their out-

puts are summed at an integrator (IC1 pins 8, 9 & 10), which drives the series pass con-

trol element (Q16). Forward and reflected power are summed so that, under high output VSWR, the power control turns the PA down. This is because the control loop adjusts for the same DC voltage from the directional coupler that would have been present if there were no reflected power. 2.3.2 Driver Power Level The maximum output power of the T889 can be limited by placing a ceiling on the driver output power level using RV69 (accessible through the side cover). For example, if RV69 is set for a maximum output power of 50W, the range of adjustment using RV63

(front panel power adjust) will be 20 to 50W. 2.3.3 Thermal Protection At excessively high temperatures, the output power will automatically reduce to a pre-

set level (set by RV74), thus preventing the PA from overheating. A thermistor controlled voltage divider (R68, R72) applies a voltage to a comparator with hysteresis (IC1 pins 12, 13 & 14). The output current from the comparator is summed into the power control network via RV74 so that the power level to which the PA must turn down may be set. 2.3.4 Forward And Reverse Power Alarms If forward power drops below, or reverse power rises above, presettable limits, alarms may be triggered. The alarm outputs are open drain configuration and are low under normal conditions

(i.e. forward and reverse power levels are normal). IC1 pins 1, 2 & 3 and pins 5, 6 & 7 form comparators with thresholds adjusted via RV48 and RV52 respectively. The inputs are from the forward and reverse power signals from the directional coupler, buffered by IC3 pins 1, 2 & 3 and pins 5, 6 & 7. Thus, the power levels at which the forward and reverse power alarms are triggered are defined by RV48 and RV52 respectively. Copyright TEL 02/10/95 2.6 Circuit Operation M889-00 2.3.5 Forward And Reverse Power Metering Forward and reverse power signals from the two IC3 buffers are available for metering purposes. The output currents are adjustable via RV43 (forward power) and RV57

(reverse power). 2.3.6 Fan Control Circuitry Tx Key Invert Q19 High Temp. Sense Low Temp. Sense NTC R72 NTC R116 Comparator Ref

+70 C, and pins 12, 13 & 14 at temperatures greater than -10 C. A logic AND function is applied to the comparator outputs by Q20 and Q21, thereby turning on the fan unconditionally (via Q17 and Q18) if the heatsink temperature exceeds +70 C. A logic OR function is applied to comparator IC3 pins 8, 9 & 10 and Tx KEY signals, thereby turning on the fan when the transmitter is keyed and the temperature is between -10 C and +70 C. If the temperature drops below -10 C, Q21 is turned off, preventing either Q19 or Q20 from activating the fan. 02/10/95 Copyright TEL M889-00 3 Introduction To Servicing 3.1 Introduction To Servicing This section provides some general and advisory information on servicing procedures.

Copyright TEL 02/10/95 3.6 3.3 Introduction To Servicing M889-00 Component Replacement 3.3.1 Leaded Components Whenever components are removed from or fitted to the PCB, care must be taken to avoid damage to the track. The two satisfactory methods of removing components from PTH PCBs are detailed below. Note:

The first method requires the use of a desoldering station, e.g. Philips SBC 314 or Pace MBT-100E. 3.3.1.1 Desoldering Iron Method Place the tip over the lead and, as the solder starts to melt, move the tip in a circu-

lar motion. Start the suction and continue the movement until 3 or 4 circles have been com-

pleted. Remove the tip while continuing suction to ensure that all solder is removed from the joint, then stop the suction. Before pulling the lead out, ensure it is not stuck to the plating. If the lead is still not free, resolder the joint and try again. Note:

The desoldering iron does not usually have enough heat to desolder leads from the ground plane. Additional heat may be applied by holding a sol-

dering iron on the tip of the desoldering iron (this may require some addi-

tional help). 3.3.1.2 Component Cutting Method Cut the leads on the component side of the PCB. Heat the solder joint sufficiently to allow easy removal of the lead by drawing it out from the component side: do not use undue force. Fill the hole with solder and then clear with solderwick. 02/10/95 Copyright TEL M889-00 Introduction To Servicing 3.7 3.3.2 Surface Mount Devices Caution:

Surface mount devices (SMD's) require special storage, handling, removal and replacement techniques. This equipment should be serv-

iced only by an approved Tait Dealer or Service Centre equipped with the necessary facilities. Repairs attempted with incorrect equipment or by untrained personnel may result in permanent damage. If in doubt, contact Tait Electronics Ltd or your nearest Tait Branch or Subsidiary. Copyright TEL 02/10/95 3.8 3.4 Caution:

Introduction To Servicing M889-00 To Replace PA Transistors As the location of certain components in the PA is critical to perform-

ance, it is important that any components removed or disturbed are refitted in EXACTLY the same position. Caution:

Do not solder the tabs before torquing down otherwise the device may be broken. 3.4.1 Capacitor /Transistor Spacing Refer to Figure 3.2. 3.4.1.1 Q1 (2SC2933 Pre-Driver) Before attempting to remove Q1, measure the distance between the capacitors labelled c and the transistor body (measurement a) so that the capacitors can be replaced in exactly the same position. Note:

Be sure to measure between the transistor body and the tabs (not the body) of the capacitors. Position the capacitors labelled b hard up against the transistor body. 3.4.1.2 Q2, Q3, Q4, Q5 & Q6 (SD1414) Position all capacitors labelled b hard up against the transistor body. 3.4.2 Replacement Procedure Desolder the tabs (and grounding clips if an SD1414) by heating with a soldering iron and lifting away from the PCB with a thin stainless steel spike, or screw-

driver. Unscrew the transistor and remove the device. Smear the face of the replacement device with heatsink compound and tighten it securely (torque setting 6lb-in./0.7Nm) to the heatsink. If you are replacing an SD1414, remember to fit new grounding clips. Solder the tabs. Replace each capacitor as instructed in Section 3.4.1. 02/10/95 Copyright TEL M889-00 Introduction To Servicing 3.9 measurement a Grounding Clips b c b Q2 b b Q1 b c b Figure 3.2 Typical Transistor/Capacitor Spacing (Q1 & Q2 Shown) Copyright TEL 02/10/95 3.10 3.5 Introduction To Servicing M889-00 To Remove The PCB From The Heatsink Most components are soldered topside only, but in some cases access to the underside of the PCB is necessary. Remove the D-range connector. Disconnect the power feed to the fan. Remove the 13 PCB retaining screws (2 are hidden beneath the harmonic filter shield). Remove the transistor mounting screws. Remove the mounting screws for the TO-220 devices:

R6, R7, R9, R16, R17, R17a and R18. Remove the retaining screws for the wireline couplers (L13, L14, L15, L40, L41 and L42). Remove the output 50 ohm coaxial connector by unscrewing it from the heatsink casting and desoldering it from the PCB. Disconnect the input 50 ohm coaxial cable by unplugging it at the PCB. Disconnect the battery positive and negative feed wires from the PCB. Disconnect the alarm and metering wires from the PCB. Lift the PCB gently from the heatsink to gain access to the underside of the PCB. Caution:

Do not operate the PA with the PCB detached as the heatsink is used for earthing and for the dissipation of heat generated within the tran-

sistors. To replace the PCB, reverse the order of removal, taking care that the wiring is cor-

rectly routed and is not subjected to 'pinching'. 3.6 To Remove Cased Mica Capacitors Cased mica capacitors can be removed by heating the top with a heavy-duty soldering iron and gently lifting the capacitor off the PCB with a solder-resistant spike or equiva-

If the fault still exists after having progressed through them in a logical manner, contact your nearest authorised Tait Dealer or Service Centre. Further assistance may be obtained from the Customer Support Group, Radio Infrastructure Division, Tait Elec-

tronics Ltd, Christchurch, New Zealand. The following topics are covered in this section.

ponents, paying particular attention to the surface mounted devices (SMD's). Check for defective solder joints. If repair or replacement is considered necessary, refer to Sections 3.3, 3.4, 3.5 and 3.6. 5.2 Component Checks If a transistor is suspected of faulty operation, an indication of its performance can be assessed by measuring the forward and reverse resistance of the junctions. First make sure that the transistor is not shunted by some circuit resistance (unless the device is completely desoldered). A 20k ohm/V or better multimeter should be used for taking the measurements, using only the medium or low resistance ranges. The collector current drawn by multi-junction transistors is a further guide to their per-

formance. If an IC is suspect, the most reliable check is to measure the DC operating voltages. Due to the catastrophic nature of most IC failures, the pin voltages will usually be markedly different from the recommended values in the presence of a fault. The recommended values can be obtained from either the circuit diagram or the component data catalogue. 5.3 DC Checks Check that +13.8V is present on the collectors of Q2, Q3, Q4, Q5 and Q6. Make this measurement when the transmitter is not keyed. Check that approximately 8-13.8V is present on the collector of Q1 (the level is dependent on RV69 being set to maximum). Check that +13.8V is present at pin 4 of IC3. Check that approximately +12V is present at pin 4 of IC1 (the level is dependent on RV69 being set to maximum). Check that +7.0V is present at the output of regulator IC2.

The lower guide rail is located in the rack frame with three screws, two at the rear and one at the front. The short upper guide rail is located with just one screw. The PA is secured into the guide with two front panel mounting screws. The RF input via the rear panel BNC connector should be connected to an adjacent T881 transmitter. The RF output is via the rear N-type connector, whilst all DC, audio and control connections are via the D-range connector. The guide rails will allow the PA to be latched in the extended position (refer to Figure 6.3).

Ensure that the cables are not sub-

jected to any stresses due to tight bends or incorrect lengths. The RF coaxial cables to the BNC and N-type connectors should be free from acute bends or twists. If access to the rear of the rack frame is restricted, the cables should be long enough to permit full withdrawal of the chassis from the guide. Pin 9

This section contains the following information. Section 7.1 7.2 Introduction T889 PA PCB Title IPN 220-01326-01 Page 7.1.3 7.2.1 Copyright TEL 02/10/95 7.1.2 PCB Information M889-00 02/10/95 Copyright TEL M889-00 7.1 Introduction PCB Identification PCB Information 7.1.3 All PCBs are identified by a unique 10 digit number, the last 2 digits of which define the issue status. The issue status starts at 00 and increments through 01, 02, 03, etc. as the PCB is updated. Some issue PCBs never reach full production status and are therefore not included in this manual. A let-

ter following the 10 digit IPN has no relevance in identifying the PCB for service purposes. Parts Lists The 10 digit numbers (000-00000-00) in this Parts List are internal part numbers (IPNs). Your spare parts orders can be handled more efficiently if you quote the IPN and provide a brief descrip-

tion of the part. The components listed in this parts list are divided into two main types: those with a circuit refer-

ence (e.g. C2, D1, R121, etc.) and those without (miscellaneous and mechanical). Those with a circuit reference are grouped firstly by PCB, then by component type in numerical order. Each component entry comprises three or four columns: the circuit reference, variant number (if applicable), IPN and description. A number in the variant column indicates that this component is fitted only to that variant. The miscellaneous and mechanical section lists the variant and common parts in IPN order. Grid Reference Index To assist in locating components and labelled pads on the PCB layouts and circuit diagrams, a com-

ponent grid reference index has been provided. This index lists the components and pads in alpha-

betical order, along with the appropriate alphanumeric grid references. The first digit in the circuit diagram reference is the sheet number, and the last two characters give the location of the component on that sheet. The first digit in the PCB layout reference is a 1 or 2, indicating the top or bottom side layout respectively, and the last two characters give the location of the component on that diagram. Using CAD Circuit Diagrams Reading a CAD circuit diagram is similar to reading a road map, in that both have an alphanumeric border. The circuit diagrams in this manual use letters to represent the horizontal axis, and num-

bers for the vertical axis. These circuit diagram grid references are useful in following a circuit that is spread over two or more sheets. When a line representing part of the circuitry is discontinued, a reference will be given at the end of Copyright TEL 02/10/95 7.1.4 PCB Information M889-00 the line to indicate where the rest of the circuitry is located. The first digit refers to the sheet number

(printed on the bottom right hand corner of the CAD diagram) and the last two characters refer to the location on that sheet of the continuation of the circuit (e.g. 1-D4). If more than one line is represented (indicated by a double thickness line), a dot with a reference label will follow the route each individual line represents. 02/10/95 Copyright TEL M889-00 7.2 T889 PA PCB This section contains the following information.
