M830P-00 Mechanical A2.1Copyright TEL 01/07/002 Mechanical2.1 Torx Recess Head ScrewsTorx recess head screws are becoming the standard screw head type in all T800 Series IIequipment, with Pozidriv and Philips recess head screws being used in fewer applica-tions. The Torx recess head has the advantage of improved screwdriver tip location, reducingthe chances of screw head damage caused by the driver tip rotating within the recess. Inaddition, using a ball-tip Torx screwdriver allows you to drive a Torx head screw withthe driver on a slight angle, which can be useful in situations where access is restricted.It is important that you use the correct Torx screwdriver tip:M3 screws - T10M4 screws - T20.Figure 2.1 below shows a typical Torx recess head screw (actual hardware may differslightly from this illustration due to variations in manufacturing techniques).Figure 2.1 Torx Screw Identification"star" shaped recess withsix internal notches
A2.2 Mechanical M830P-0001/07/00 Copyright TEL2.2 Pozidriv & Philips Recess Head ScrewsPozidriv and Philips recess head screws will continue to be used in T800 Series II equip-ment in a few special applications. It is important that you use the correct type and sizescrewdriver for each screw type to avoid damaging the screw head. It is particularly important that you do not use Philips screwdrivers on Pozidriv screwheads as the tapered driving flutes of the Philips screwdriver do not engage correctlywith the parallel-sided slots in the Pozidriv screw head. This can result in considerabledamage to the screw head if the screwdriver tip turns inside the recess.Note: If you find you need excessive downwards pressure to keep the screwdrivertip in the Pozidriv screw head, you are probably using the wrong type and/or size screwdriver.Figure 2.2 below shows the main differences between typical Pozidriv and Philips screwheads and screwdriver tips (actual hardware may differ slightly from these illustrationsdue to variations in manufacturing techniques).

M830P-00 Component Replacement A3.1Copyright TEL 01/07/003 Component Replacement3.1 Leaded ComponentsWhenever you are doing any work on the PCB that involves removing or fitting compo-nents, you must take care not to damage the copper tracks. The two satisfactory meth-ods of removing components from plated-through hole (PTH) PCBs are detailed below.Note: The first method requires the use of a desoldering station, e.g. Philips SBC314 or Pace MBT-100E.3.1.1 Desoldering Iron MethodPlace 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 fromthe 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 leadsfrom 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).3.1.2 Component Cutting MethodCut the leads on the component side of the PCB.Heat the solder joint sufficiently to allow easy removal of the lead by drawing itout from the component side: do not use undue force.Fill the hole with solder and then clear with solderwick.
A3.2 Component Replacement M830P-0001/07/00 Copyright TEL3.2 Surface Mount DevicesCaution: Surface mount devices (SMDs) require special storage, handling,removal and replacement techniques. This equipment should be serv-iced only by an approved Tait Dealer or Customer Service Organisa-tion equipped with the necessary facilities. Repairs attempted withincorrect equipment or by untrained personnel may result in perma-nent damage. If in doubt, contact your nearest Tait Dealer or CustomerService Organisation.3.3 Cased Mica CapacitorsCased mica capacitors can be removed by heating the top with a heavy-duty solderingiron and gently lifting the capacitor off the PCB with a solder-resistant spike or equiva-lent.

M830P-00 T837 General Information C1.5Copyright TEL 01/07/001.1 IntroductionThe T837 is a synthesised, microprocessor controlled, DFSK low speed paging exciterdesigned for single or multichannel1 operation in the 148 to 174MHz frequency range2.With a standard power output of only 800mW, the exciter is designed for use with theT839 100W power amplifier. The RF section of the exciter comprises a frequency syn-thesiser which provides 170mW of frequency modulated RF drive to a two stage, wideband output amplifier. The synthesiser frequency is programmed via the serial commu-nications port.The low speed paging modulator section provides DFSK modulation. It incorporates aTCXO frequency reference and uses two point modulation to achieve modulation ofdata rates from 2400bps down to DC.All components except those of the VCO are mounted on a single PCB. This is securedto a die-cast chassis which is divided into compartments to individually shield each sec-tion of circuitry. Access to both sides of the main circuit board is obtained by removingeach of the chassis lids. There is provision within the chassis to mount small optionPCBs.The front panel has two indicator LEDs to show when the transmit carrier is on (red)and when the DC supply is connected (green). The T837 is 60mm wide and occupies asingle space in a Tait rack frame, which has the ability to accommodate up to sevenstandard modules.1. Although you can program the microcontroller with up to 128 channels, you must carry out the modulation adjustment procedure if you change frequency (see Section 3.5).2. Although capable of operating over the 148-174MHz frequency range, the T837 has an 8MHz VCO switching range (see Section 1.2.3 and Section 3.1).

It runs from internal ROM and RAM, thus leavingall four ports free for input/output functions.Non-volatile data storage is achieved by serial communication with a 16kBit EEPROM(IC820). This serial bus is also used by the microcontroller to program the synthesiser(IC740).The main tasks of the microcontroller are as follows:• program the synthesiser;• interface with the PGM800Win programming software at 9600 baud via theserial communication lines on D-range 1 (PL100);• coordinate and implement timing control of the exciter;• control the front panel "Supply" LED (refer to Section 5.3).5V Reset5V DigitalRegulator Watchdog ResetChannelSelectPortAuxiliaryOutputPortMicrocontroller12.8MHzClockMicrocontroller CavityExternalSerialPortEEPROM SynthesiserConverter

The synthesiser receives the dividerinformation from the control microprocessor via a 3 wire serial bus (clock, data, enable).When the data has been latched in, the synthesiser processes the incoming signals fromthe VCO buffer (fin) and the phase modulator (fref).A 12.8MHz reference frequency is fed from the paging modulator section to the fre-quency synthesiser Refin (IC740 pin 20). This reference frequency is derived from theVCXO (X101), which is locked to the internal frequency standard provided by the TCXO(X100). The reference frequency has been modulated in the VCXO by the incoming datato allow the synthesiser loop to modulate down to DC. This 12.8MHz reference fre-quency is divided down to 6.25kHz or 5.0kHz in the synthesiser IC (IC740).A buffered output of the VCO (Q795) is divided with a prescaler and programmabledivider which is incorporated into the synthesiser chip (IC740). This signal is comparedwith the phase modulated reference signal at the phase detector (also part of the synthe-siser chip). The phase detector outputs drive a balanced charge pump circuit (Q760,Q770, Q775, Q780, Q785) and active loop filter (IC750 pins 5, 6 & 7) which produces aDC voltage between 0V and 20V to tune the VCO. This VCO control line is further fil-tered to attenuate noise and other spurious signals. Note that the VCO frequencyincreases with increasing control voltage.If the synthesiser loop loses lock, a pulsed signal appears at LD (pin 2) of IC740. Thissignal is filtered and buffered by IC750 pins 1, 2 & 3, producing the Lock-Detect signalused to shut off the power supply to the drive amplifier.

C2.6 T837 Circuit Operation M830P-0001/07/00 Copyright TEL2.3.1 Two Point ModulationFrequency modulation occurs by modulating both the VCO input and the synthesiserreference input. This process is called two point modulation and ensures a flat modula-tion response from 0 to 2400bps.The PLL has a fast response time, allowing a Tx key-up time of <30ms. Because of thisfast response time the PLL sees lower modulation frequencies superimposed on theVCO as an error and corrects for it, resulting in no modulation on the carrier. At modu-lation frequencies greater than 300Hz the loop cannot correct fast enough and modula-tion is seen on the carrier. To achieve low frequency modulation, the reference oscillator is also modulated so thatthe phase detector of IC740 detects no frequency error under modulation. Thus, thesynthesiser loop will not attempt to correct for modulation and the data frequencyresponse of the transmitter remains unaffected.
M830P-00 T837 Circuit Operation C2.7Copyright TEL 01/07/002.4 VCO(Refer to the VCO circuit diagram in Part E.)The VCO transistor (Q1) operates in a common source configuration, with an LC tankcircuit coupled between its gate and drain to provide the feedback necessary for oscilla-tion. The VCO control voltage from the loop filter (IC750 pin 7) is applied to the vari-caps (D1-D4) to facilitate tuning within an 8MHz band of frequencies. A trimcap (CV1)is used for coarse tuning of the VCO. The output from the oscillator circuit drives a cas-code amplifier stage (Q2, Q3) which supplies +10dBm (typically) to a further stage ofamplification, Q5. This is the final amplifier on the VCO PCB, and delivers +22dBm(typically) to the exciter drive amplifier.A low level "sniff" is taken from the output of Q3 and used to drive the divider buffer(Q795) for the synthesiser (IC740).The VCO operates at the actual output frequency of the exciter, i.e. there are no multi-plier stages. The VCO is modulated by superimposing the data signal onto the controlvoltage and by frequency modulating the reference signal.2.4.1 VCO Supply The VCO is supplied from two switched +9V supplies under the control of the Tx-Reg.supply.The VCO (Q1) and buffer amplifier (Q2 & Q3) are supplied from one +9V switched sup-ply by Q540 via the capacitor multiplier (Q550, C550).The output amplifier is supplied from the other +9V supply by Q520, Q530, and Q510.A delay circuit holds the VCO on for a short time after the Tx-Reg. supply has beenswitched off. This is to allow the RF power circuits (both exciter and PA) to ramp downin the correct manner before the VCO is switched off.
C2.8 T837 Circuit Operation M830P-0001/07/00 Copyright TEL2.5 Low Speed Paging Modulator(Refer to the low speed paging modulator circuit diagram (sheet 2) in Section 6.2.)2.5.1 GeneralThe T837-2X-102X is a dedicated paging exciter. The low speed paging modulator sec-tion of the exciter accepts TTL data at the D-range input and modulates the synthesiserusing a two point modulation method that provides modulation of data input frequen-cies of 2400bps down to DC (all 1’s or all 0’s).The paging modulator section incorporates a TCXO frequency reference and a modulat-able VCXO which is locked to the reference frequency from the TCXO.The paging modulator also has provision for fitting an optional FFSK modem PCB.2.5.2 AFC/PLL OperationFigure 2.4 T837 AFC Block DiagramThe TCXO is the default frequency standard. In PLL mode, the slave 12.8MHz VCXO isphase locked to the TCXO. Both the TCXO and the VCXO outputs are clipped in IC100and IC102 and then frequency divided by 4 in the twisted ring counters, IC105 (TCXO)and IC110 (VCXO). The slave VCXO is also fed to the synthesiser reference input.Each twisted ring counter provides four divide-by-four outputs, the Q and not Q havingthe relative phases 0°, 90°, 180° and 270°. These two signals are combined in the twoXOR gate phase discriminators in IC115 to provide two beat frequencies that are inphase quadrature. Both these outputs are filtered to pass the low frequency beat signal,which is a 5Vpp triangle wave. The output from pin 8 of IC115 is then differentiated to provide a further 90° phaseshifted square wave output on pin 14 of IC120. The amplitude of the output is propor-tional to the frequency difference between the TXCO and the VCXO. The square waveis then rectified by gating the signal with an inverted version of itself through a CMOSVCXO AFC12.8MHzTCXOModulatedReference+-1SummingAmp.Loop FilterData Line
M830P-00 T837 Circuit Operation C2.9Copyright TEL 01/07/00switch. The switch is controlled by a square wave derived from the triangle wave onpin 7 of IC120. This square wave will either be in-phase or inverted with respect to theoutput on pin 14 of IC120, depending on whether the VCXO frequency is higher orlower than the TCXO frequency.The output from the CMOS switch (pin 14 of IC150) is a direct voltage which has ampli-tude and sense that is relative to the beat frequency. This signal is used as the controlvoltage for the VCXO. The rectified signal is then summed with an inverted version ofthe data, which cancels the effect of the data on the loop filter but still allows the VCXOto follow the TCXO frequency. Although the VCXO and TCXO are not on the same fre-quency when data is being applied, the VCXO frequency will not drift with respect tothe TCXO.2.5.3 Data PathThe input data enters the radio via pin 12 of D-range 1 (PL100). The data is fed into thepaging modulator at I/O pad P101, which is buffered by Q100, and then through anXOR gate (IC115 pins 2 & 3) which gives the option of inverting the data. IC140 pins 5 & 6 translate the level of the signal to 9Vpp, and then the data passesthrough an attenuator and data filter. The data path is switched at the output of the fil-ter by IC150 pins 1, 2 & 15, which allows the data to be removed from the AFC loop fortesting purposes. From the switch the data travels three paths:• The first path is via RV100 to the LOOP-MOD output to modulate the VCO.• The second path is through RV101 to the summing amp. This data modulatesthe control line of the VCXO, which produces the modulated reference.• The third data path, which originates at the switch, is the feedforward datapath. The data is inverted, attenuated by RV102 and then summed with theoutput of the AFC. The effect of this data path is to stop the loop filter fromcorrecting the VCXO frequency deviation caused by the data on the data line.2.5.4 External Reference Frequency (T837-2X-1021 Only)The paging modulator section of the T837-2X-1021 exciter incorporates an additionalsynthesiser (*IC200) which can be configured to provide a 12.8MHz reference frequencyfrom an external frequency standard. This external frequency can be from 100kHz up to25.6MHz in 100kHz steps.When using an external reference, you must set the onboard synthesiser’s reference fre-quency according to the frequency of the external reference. This is achieved by placingresistors *%R240 - *%R247 in a pattern corresponding to a binary number which repre-sents the reference divider ratio (see Section 3.6).The internal TCXO (%X100) is used as the standard reference frequency, but is phase-locked to the external frequency when this is applied.

The reference frequency canbe adjusted by the trimmer on the TCXO itself.When an external reference frequency is present, *Q104 switches on and *IC160 switchesthe synthesiser phase detector output voltage to the AFC input of the internal TCXO. Abuffered 12.8MHz output of the internal TCXO is fed back to the synthesiser oscillatorinput and compared with the external reference frequency, thus ensuring that the inter-nal TCXO is phase-locked to the external reference frequency.The synthesiser Lock-Detect signal drives an LED *D116 on the main PCB which is litwhen the synthesiser is locked to the external reference frequency. The Lock-Detect sig-nal is also fed to pin 8 of D-range 1 (PL100) for external monitoring purposes. The out-put is low when the synthesiser is locked.2.5.5 Keying InputsThere are two ways to key the exciter: • pulling the Tx-Key line low (pin 13 on D-range 1 [PL100]) at the rear of the set);• via the modem carrier detect line when the optional modem PCB is fitted.Note: Link S100 must be connected when using the Tx-Key line input.2.5.6 Paging Modulator LinksThree solder links are provided in the paging modulator circuit. Their functions aredescribed in the following table:Link FunctionStandardSetting DescriptionS100 Tx-Key linked ties the Tx-Key line to +5V for earthed Tx-Key line operationS101 invert data not linked inverts the incoming dataS102 invert key not linked inverts the key line (connected when using modem carrier detect)

A 5.3Vregulator (IC630) runs directly from the 13.8V rail, driving much of the synthesiser cir-cuitry. It is also used as the reference for a DC amplifier (IC640, Q630, Q620) which pro-vides a medium current capability 9V supply.A switching power supply (Q660, Q670) runs from the 9V supply and provides a lowcurrent capability +20V supply. This is used to drive the synthesiser loop filter (IC750),giving a VCO control voltage range of up to 20V, and the Lock-Detect amplifiers.Ultimate control of the transmitter is via the Tx-Reg. supply, switched from 9V by Q610.This is enabled via the Tx-Enable signal from the modulator, and microprocessor. A crowbar diode is fitted for protection against connection to a power supply of incor-rect polarity. It also provides transient overvoltage protection.Note: A fuse must be fitted in the power supply line for the diode to provide effec-tive protection.CrowbarDiode LVI5VRegDCAmp SwitchingPS 5V DigRegPowerSwitch13.8VNom. 5V 5V Dig9V 20V13.8V Nom.From RearD-RangeTx EnableBufferTx Reg.+9VµPWatchdogTimerMicro-controllerµPReset

M830P-00 T837 Circuit Operation C2.13Copyright TEL 01/07/002.8 Exciter Drive Amplifier(Refer to Figure 2.1 and the exciter circuit diagram (sheet 3) in Section 6.2.)A two-stage, wide band amplifier (Q365, Q370) provides an output level of approxi-mately 800mW (+29dBm) for an input of 170mW (+22dBm) from the VCO. IC330 pins5, 6 & 7, Q310, and Q315 provide a 10.5V regulated supply for the exciter.To reduce the spurious output level when the synthesiser is out-of-lock, the Tx-Reg. andLock-Detect signals are gated to inhibit the exciter control circuit and to switch off theRF signal at the input to the drive amplifier. This is achieved by a PIN switch attenuator(D340, D350, D360).Cyclic keying control is provided by additional circuitry consisting of several timedelay, ramp and gate stages:• Q305, IC330 pins 5, 6 & 7 power ramping• Q340, Q345 Tx-Reg. and Lock-Detect gate• Q320, Q325, Q330, Q335 delay and PIN switch drive.This is to allow the RF power circuits (both exciter and PA) to ramp up and down in acontrolled manner so that minimal adjacent channel interference is generated duringthe transition.R359, R342 and R344 form a 6dB attenuator to provide good VCO/drive amplifier isola-tion.The output attenuator (R360, R362, R364, R366) assists in reducing exciter/PA interac-tion while also ensuring a good match for Q370.Note: The exciter provides a DC control signal to the PA via the RF coax. This isinjected via L390.

If you want to switch to a frequency that is within the8MHz VCO switching range (i.e. ±4MHz from the factory programmed frequency), youwill need to:• reprogram the exciter with the PGM800Win software (refer to the PGM800Winprogramming kit and Section 3.2 below);• carry out the modulator adjustment procedure described in Section 3.5.However, if you want to switch to a frequency outside the 8MHz VCO switching range,you will have to:• reprogram the exciter with the PGM800Win software;• carry out the synthesiser alignment procedure described in Section 3.4;• carry out the modulator adjustment procedure described in Section 3.5.3.2 Channel ProgrammingYou can program up to 128 channel frequencies into the exciter’s EEPROM memory(IC820) by using the PGM800Win software package and an IBM PC. You can also usePGM800Win to select the exciter’s current operating frequency (or "default channel").If the exciter is installed in a rack frame, you can program it via the programming portin the speaker panel. However, you can also program the exciter before it is installed ina rack frame as follows:• by using a T800-01-0010 calibration test unit;•via D-range 1.If you do not use the T800-01-0010, you will have to connect the PC to the exciter via amodule programming interface (such as the T800-01-0004).For a full description of the channel programming procedure, refer to the PGM800Winprogramming software user’s manual.1.

Monitor the exciter output frequency and adjust RV102 (DC frequency offset) togive an output frequency of Fcarrier + 4.5kHz.Remove the +5V DC from pin 12 and apply a 100Hz 5Vp-p square wave to pin 12.Monitor the signal at TP100 with an AC coupled oscilloscope set to 50mV/div.and adjust RV101 (reference modulation) until the triangle wave amplitude isminimised.Change the frequency of the square wave to 600Hz.Monitor the frequency deviation on the exciter output with a modulation meterand adjust RV100 (VCO modulation) to obtain ±4.5kHz deviation.Monitor the VCO control line at PL4-1 or the junction of L1 and R1 in the VCOusing an AC coupled oscilloscope set to at least 20mV/div.Change the frequency of the square wave back to 100Hz and check that the controlline still has a good trapezoidal wave form with flat top and bottom.Note 1: You may have to readjust RV101 & RV100 alternately to achieve a squarewave on the VCO control line at both 600Hz and 100Hz with a deviation of±4.5kHz. Figure 3.2 shows a typical 100Hz VCO control line wave formwith RV101 and RV100 set correctly.Figure 3.2 T837 100Hz VCO Control Line Wave FormNote 2: If the lower cut off frequency of an AC coupled oscilloscope is too high,excessive distortion may be introduced which will result in ‘sag’ on thesquare wave displayed. Determine if this is a problem by directly monitor-ing the original square wave source and observe any sag. If there is sag,switch the oscilloscope to DC and use a 10µF capacitor in series with theoscilloscope probe (observing the correct polarity) to directly monitor theVCO control line. Note that the trace settling time will be approximatelyone minute.
M830P-00 T837 Initial Tuning & Adjustment C3.7Copyright TEL 01/07/003.6 External Reference Frequency Configuration (T837-2X-1021 Only)When using an external reference frequency, you must set the onboard synthesiser’s ref-erence frequency according to the frequency of the external reference. This is achievedby placing resistors *%R240 - *%R247 in a pattern corresponding to a binary numberwhich represents the reference divider ratio.If you are using a 10MHz external reference frequency, you need only carry out steps 4and 5 in this section. You do not need to carry out steps 1, 2 and 3 because the T837 hasalready been configured at the factory for a 10MHz external reference.However, if you are using an external reference frequency other than 10MHz, you mustconfigure the internal synthesiser as described in steps 1, 2 and 3 before proceeding tosteps 4 and 5.1. Divide the external oscillator frequency by 100kHz.2. Convert the result to binary. You can use the following table to do this: select thebinary values in row three which add up to the result obtained in step 1, thenplace a “1” in these positions and a “0” in the others.3. Where there is a “0” in the binary number, place a zero ohm resistor in the corre-sponding component location shown in the table.

If repair or replacement is considered necessary, referto Section 3 of Part A.5.2 Component ChecksIf you suspect a transistor is faulty, you can assess its performance by measuring the for-ward and reverse resistance of the junctions. Unless the device is completely desol-dered, first make sure that the transistor is not shunted by some circuit resistance. Use agood quality EVM (e.g. Fluke 75) for taking the measurements (or a 20k ohm/V or bet-ter multimeter, 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. Dueto the catastrophic nature of most IC failures, the pin voltages will usually be markedlydifferent from the recommended values in the presence of a fault. The recommendedvalues can be obtained from either the circuit diagram or the component data catalogue.5.3 Front Panel LED IndicatorThe green "Supply" LED on the T837 front panel will flash according to the conditionsdescribed in the following table:Where two or more conditions occur at the same time, the precedence is in the ordershown above (i.e. T837 linked has the highest priority, followed by internal error).Flash Rate Conditionfast (D sec. on/D sec. off approx.)

M830P-00 T837 PCB Information C6.1.3Copyright TEL 01/07/006.1 IntroductionProduct Type IdentificationYou can identify the exciter type by checking the product code printed on a label on the rear of thechassis (product codes are explained in Section 1.3 in this Part of the manual, and Figure 1.1 in PartA shows typical labels). You can further verify the product type by checking the placement of anSMD resistor in the table that is screen printed onto the top side of the PCB, similar to the exampledrawn below. In this example, the resistor indicates that the product was built as a T837-20-XXXX. Note: The only function of this resistor is to indicate the product type. It has no effect on thecircuitry or operation of the exciter.PCB IdentificationAll PCBs are identified by a unique 10 digit “internal part number” (IPN), e.g. 220-12345-00, whichis screen printed onto the PCB (usually on the top side), as shown in the example below:The last 2 digits of this number define the issue status, which 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 there-fore not included in this manual. A letter following the 10 digit IPN has no relevance in identifyingthe PCB for service purposes.Note: It is important that you identify which issue PCB you are working on so that you canrefer to the appropriate set of PCB information.837- PRODUCT TYPE837- 837-10 837-20837- 837-13 837-23PRODUCT TYPE 837-15 837-25

M830P-00 T838/839 General Information D1.5Copyright TEL 01/07/001.1 IntroductionThe T838 & T839 are FM base station power amplifiers designed for single or multichan-nel operation in the 148 to 174MHz frequency range. The typical output power capabil-ities are as follows:T838 - 10 to 60WT839 - 20 to 120W.The T838 PA comprises a single broad band RF power module whose output is filteredbefore being fed to the output socket.The T839 PA comprises two broad band RF power modules whose outputs are recom-bined (using a quadrature hybrid combiner) and filtered before being fed to the outputsocket. This dual module design enables the transmitter to produce at least one quarterof its rated power if one of the modules fails.VSWR and thermal protection is incorporated into the basic design, while monitoringand alarm signals are available for both forward and reverse power. The output poweris adjustable from the front panel.The main PCB is mounted directly on a die-cast chassis/heatsink. Extensive use ismade of the latest surface mount technology. Effective RF isolation between the PA con-trol circuitry and RF stages is achieved by internal metal shields.Forced air cooling for the heatsink is provided on the T839 by a fan, which is activatedwhenever the transmitter is keyed. Thermal sensors will also activate the fan automati-cally if the internal temperature reaches an unacceptable level.The T838 has a width of 60mm and occupies a single space in a Tait rack frame, whichhas the ability to accommodate up to seven standard modules.

D2.4 T838/839 Circuit Operation M830P-0001/07/00 Copyright TEL2.2 RF Circuitry(Refer to the RF & thermistor control sections circuit diagram in Section 5.)The T838 consists of a single RF power module (#IC201) which delivers 60-70W. Theinput signal is fed directly into the module, and the output from the module is passed tothe antenna socket via the directional coupler and low pass filter.The T839 consists of two RF power modules (#IC201 & *#IC202), each of which delivers60-70W. The input signal to these modules is split via a 3dB quadrature hybrid (*IC203).The outputs from the modules are recombined by a second 3dB quadrature hybrid(*IC205) before being passed to the antenna socket via the directional coupler and lowpass filter.The directional coupler senses forward and reflected power, which is rectified (D201 &D203) and passed to the control circuitry for metering, alarm and power control pur-poses.Power control is via a series pass transistor (Q137), which controls the supply voltage onpin 2 of #IC201 in the T838, and pin 2 of both #IC201 and *#IC202 in the T839.

D2.6 T838/839 Circuit Operation M830P-0001/07/00 Copyright TEL2.3.1 Power ControlThe DC voltages from the directional coupler representing forward and reflected powerare buffered by the two voltage followers, IC103 pins 1, 2 & 3 and pins 8, 9 & 10. Theiroutputs are summed at an integrator (IC105 pins 1, 2 & 3), which drives the series passcontrol elements (Q135 & Q137).Forward and reflected power are summed so that, under high output VSWR, the powercontrol turns the PA down. This is because the control loop adjusts for the same DCvoltage from the directional coupler that would have been present if there were noreflected power.2.3.2 Driver Power LevelThe maximum output power of the T838/839 can be limited by placing a ceiling on thedriver output power level using RV115 (accessible through the side cover). For exam-ple, if RV115 is set for a maximum output power of 50W, the range of adjustment usingRV109 (front panel power adjust) will be 20 to 50W.Caution: The driver power level clamp (RV115) is factory set to give a maximumpower output of 60W for the T838 and 120W for the T839. The unit maybe damaged if this level is increased.2.3.3 Thermal ProtectionAt excessively high temperatures, the output power will automatically reduce to a pre-set level (set by RV113), thus preventing the PA from overheating. Ambient temperature within the PA is measured by a thermistor controlled voltagedivider (R168, R237) which applies a voltage to a comparator with hysteresis (IC101pins 8, 9 & 10). This thermistor is located on the PCB in the low pass filter cavity.Thermal protection is also provided for each RF power module to prevent the moduleitself from overheating. This protection consists of a thermistor controlled voltagedivider (R207, *R215 and R220, R219) which sets a voltage on a comparator with hyster-esis (IC204 pins 1, 2 & 3 and 5, 6 & 7). These thermistors are located on the moduleflanges.The output current from all comparators is summed into the power control network viaRV113 so that the power level to which the PA must turn down may be set.

The inputs are from the forward and reverse power sig-nals from the directional coupler, buffered by IC103 pins 1, 2 & 3 and pins 8, 9 & 10.Thus, the power levels at which the forward and reverse power alarms are triggered aredefined by RV101 and RV105 respectively.2.3.5 Forward And Reverse Power MeteringForward and reverse power signals from the two IC1 buffers are available for meteringpurposes. The output currents are adjustable via RV103 (forward power) and RV107(reverse power).2.3.6 Fan Control CircuitryFigure 2.4 T839 Fan Control Logic Diagram*Q107 *Q109 FanRef +Ref +High Temp.Sense On PCBComparatorIC101R237High Temp.Sense OnModule FlangeHigh Temp.Sense OnModule FlangeComparatorIC204Ref +ComparatorIC204*R215R219NTCNTCLow Temp.SenseComparatorRef +IC101*R116NTCNTCTx KeyInvert*Q101 OR*Q103,*R106, *R107ORQ201D202, R212,R214NAND*Q103, *Q105,*R111, *R112 Fan Driver13.8VFiltered

Do not use the factory default settings as theymay not suit your operating frequency.To obtain optimum performance from the T838/839, ensure that the exciterused in this set-up procedure is the one that will be used with the PA in theradio system.Note 2: Cables and connectors can easily cause a power loss of several watts if eithertoo long or poorly terminated. Always use the shortest possible leads (orconnectors instead of leads) between the T838/839 and power meter set-up.You will need appropriate extension leads if you wish to carry out theadjustment procedures with the T838/839 withdrawn from the rack in thelatched position. Alternatively, disconnect and withdraw the T838/839 andreconnect it behind the rack.Note 3: The actual power used may be limited by regulatory requirements. Set the exciter to the required operating frequency.Connect the exciter output to the PA input via a thru-line wattmeter with a 1Wfull scale reading. Special BNC/N leads will be required.Connect an RF power meter to the PA output connector.With the exciter not keyed:• remove the label over the adjustment hole for RV115 (driver power clamp);• set RV115 to maximum (fully clockwise);• set RV109 (front panel power control) to maximum (fully clockwise).Key on the exciter.Quickly (within 30 seconds) adjust RV115 until the output power is:T838 - 60WT839 - 120W.Adjust RV109 to set the power output to the following levels (or less if required):T838 - 50WT839 - 100W.

M830P-00 T838/839 Fault Finding D4.11Copyright TEL 01/07/004.5 Replacing RF Power ModulesCaution: Follow these instructions carefully, otherwise the module can failbecause of poor heatsinking or cracked substrates.Caution:Do not apply too much heat to the original type of thermistor assemblyas the epoxy used may give off fumes that will cause eye irritation. Ifnecessary, replace this device as a complete assembly (see note 1 below).Desolder the module and thermistor1 legs by heating with a soldering iron andlifting away from the PCB with a screwdriver or thin stainless steel spike. Undo the module screws and remove the thermistor assembly.Desolder and remove both earth tags.Gently lift the module away from the heatsink.Note: The module may be stuck down quite firmly with heatsink compound. Youmay need to carefully prise it away from the heatsink with a small screw-driver. Keep the heatsink compound clean while the module is detached.Apply a small amount of heatsink compound (Dow-Corning 340 or equivalent) tothe replacement module mounting surface. Use enough compound to ensure aneven film over the entire mounting surface.Reposition the module in the correct orientation and ensure it is well pasted to theheatsink. Replace the earth tags and thermistor1 assembly in their original positions andhand-tighten the screws, ensuring the tags and thermistor remain in place. Alter-nately tighten each screw evenly, finally torquing them down to 56N.cm/5in.lbf.with an accurate torque driver.Caution: It is essential that you apply the correct torque to these screws to allowthe module flange to expand and contract under temperature cycling.Also, do not solder any module legs before torquing down otherwisethe device may be broken.Solder all module legs to the PCB.Carefully solder the thermistor leg to the PCB1.1. Later production PAs are fitted with a different type of thermistor which you do not need to desolder from the PCB before removing a power module. Refer to the top side PCB layout diagrams in Sections 5.2 and 5.3 for further details.

There are no components on the bottom of thePCB.Remove the harmonic filter shield lid.T839 Only: Desolder the power feed to the fan from the PCB.Remove the output 50 ohm coaxial connector by unscrewing it from the heatsinkcasting and desoldering it from the PCB and harmonic filter shield wall.Unplug the input 50 ohm coaxial cable from the PCB, unscrew the BNC connectorfrom the heatsink, and remove the connector and cable.Desolder the positive and negative power feed wires from the D-range PCB.Disconnect the ribbon cable from the D-range PCB.Remove the 2 screws securing the D-range connector and PCB to the heatsink andwithdraw the assembly from the heatsink.Remove the mounting screws for the TO-220 device(s): Q137 (and *R223 in theT839).Remove the screws securing the RF power module(s): #IC201 (and *#IC202 in theT839). T839 Only: Remove the four hex nuts and washers from the splitter/com-biner hybrids (*IC203 and *IC205).Remove the 11 PCB retaining screws.Push the three LEDs out of their front panel grommets.Lift the PCB gently from the heatsink to gain access to the underside of the board.Note: #IC201, *#IC202 and *R223 may be stuck down with heatsink compound.You may need to carefully prise them away from the heatsink with a smallscrewdriver. Caution: Keep the heatsink compound clean while the PCB is detached. Anyobjects caught in the heatsink compound underneath the modulewhich prevent effective earthing and/or heatsinking will cause cata-strophic failure.Caution: Do not operate the PA with the PCB detached as the heatsink is usedfor earthing and heat dissipation.
M830P-00 T838/839 Fault Finding D4.13Copyright TEL 01/07/00To replace the PCB, reverse the order of removal, taking care that the wiring is cor-rectly positioned and not 'pinched'.Make sure that the heatsink compound has stayed clean, and that the insulatingpad for Q137 is not damaged.If you have difficulty refitting the LEDs, try pushing the body of the LED backinto the grommet with a thin screwdriver or spike.Caution: Tighten the splitter/combiner hybrid hex nuts to a torque of 22N.cm/2in.lbf. Any greater force will damage the devices.Tighten the RF power module screws to a torque of 56N.cm/5in.lbf.with an accurate torque driver. Deviating from this figure can causethe device to fail (refer to Section 4.5).

Refer to Section 1.2 in Part A for more information on anti-staticprocedures when handling these devices.This section provides the following information on the T838 and T839 power amplifiers:•parts lists• grid reference indexes• mechanical assembly drawings•PCB layouts• circuit diagrams.The T838 and T839 share the same basic design and are built on the same PCB. However, in order tosimplify the presentation of the PCB information for each product, we have provided a separateparts list, grid reference index and set of drawings for both the T838 and T839, even though this hasmeant duplicating some information (e.g. grid reference index and circuit diagrams) in each section.Section Title IPN Page5.1 Introduction 5.1.35.2 T838 Power Amplifier PCB 220-01404-03 5.2.15.3 T839 Power Amplifier PCB 220-01404-03 5.3.1

You can further verify the PA type by checking the placement of an SMDresistor in the table that is screen printed onto the PCB, similar to the example drawn below. In thisexample, the resistor indicates that the product was built as a T830 Series II compatibleT839-20-XXXX.PCB IdentificationAll PCBs are identified by a unique 10 digit “internal part number” (IPN), e.g. 220-12345-00, whichis screen printed onto the PCB (usually on the top side), as shown in the example below:The last 2 digits of this number define the issue status, which 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 there-fore not included in this manual. A letter following the 10 digit IPN has no relevance in identifyingthe PCB for service purposes.Note: It is important that you identify which issue PCB you are working on so that you canrefer to the appropriate set of PCB information.PRODUCT TYPEMODEL REV SERIESISERIESIIT839-10 3AT839-20 3AT838-10 3AT838-20 3ANote:The only function of thisresistor is to indicate theproduct type.

M830P-00 Introduction E1.1Copyright TEL 01/07/001IntroductionPCB IdentificationAll PCBs are identified by a unique 10 digit “internal part number” (IPN), e.g. 220-12345-00, whichis screen printed onto the PCB (usually on the top side), as shown in the example below:The last 2 digits of this number define the issue status, which 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 there-fore not included in this manual. A letter following the 10 digit IPN has no relevance in identifyingthe PCB for service purposes.Note: It is important that you identify which issue PCB you are working on so that you canrefer to the appropriate set of PCB information.Parts ListsThe 10 digit numbers (000-00000-00) in this Parts List are “internal part numbers” (IPNs). We canprocess your spare parts orders more efficiently and accurately if you quote the IPN and provide abrief description 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 in alphabetical order and then in numerical order withineach group. Each component entry comprises three or four columns, as shown below:The mechanical and miscellaneous section lists the variant and common parts in IPN order.circuit reference -lists componentsin alphanumericordervariant column -indicates that this isa variant componentwhich is fitted only tothe product type listedInternal Part Number -order the componentby this numberdescription -gives a brief descriptionof the component
E1.2 Introduction M830P-0001/07/00 Copyright TELParts List AmendmentsAt the front of the parts list is the Parts List Amendments box (an example of which is shownbelow). This box contains a list of component changes which took place after the parts list and dia-grams in this section were compiled. These changes (e.g. value changes, added/deleted compo-nents, etc.) are listed by circuit reference in alphanumeric order and supersede the informationgiven in the parts list or diagrams. Components without circuit references are listed in IPN order.The number in brackets at the end of each entry refers to the Tait internal Change Order document.Variant ComponentsA variant component is one that has the same circuit reference but different value or specification indifferent product types. Where two products share the same PCB, the term “variant” is also used todescribe components unplaced in one product. Variant components have a character prefix, such as“&”, “=” or “#”, before the circuit reference (e.g. &R100).The table below explains the variant prefixes used in T800 Series II products:If the variant prefix is. . . the component will. . .& change according to channel spacing= change according to frequency stability# change according to frequency band% change or be placed/unplaced for special applications*be unplaced in one product(where two products share the same PCB)Parts List AmendmentsR306 Changed from 180Ωto 560Ω(036-13560-00) to increase sensitivity (71003).circuit referenceor IPN descriptionof changeIPN of newcomponent Change Ordernumber
