Introduction
The T856 is a synthesised, microprocessor controlled FM base station transmitter
designed for single or multichannel operation in the 400 to 520MHz frequency range1
with a standard power output of 25W. The RF section of the transmitter comprises a frequency synthesiser which provides 100mW of frequency modulated RF drive to a two
stage, wide band output driver followed by a 25W power amplifier. A thermal shutdown feature is provided in the T856 in case operating temperatures exceed acceptable
levels.
The T857 is a synthesised, microprocessor controlled FM base station exciter designed
for single or multichannel operation in the 400 to 520MHz frequency range1. With a
standard power output of only 1W, the exciter is designed for use with the T858 50W or
T859 100W power amplifiers. The RF section of the exciter comprises a frequency synthesiser which provides 100mW of frequency modulated RF drive to a two stage, wide
band output amplifier.
A wide selection of audio characteristics may be obtained from the audio processor.
Optional circuit blocks are an audio compressor and a pre-emphasis stage. They can be
bypassed or linked to one or both audio inputs, and then back into the remaining audio
circuitry in almost any combination. All audio processor options are link selectable.
The synthesiser frequency is programmed via the serial communications port. Eight
channel select lines are accessible via an optional D-range connector (D-range 2 T800-03-0000) at the rear of the set.
All components except those of the VCO are mounted on a single PCB. This is secured
to a die-cast chassis which is divided into compartments to individually shield each section of circuitry. Access to both sides of the main circuit board is obtained by removing
each of the chassis lids. There is provision within the chassis to mount small option
PCBs.
The front panel controls include line sensitivity, microphone socket and carrier switch.
This switch turns on the carrier (unmodulated) as an aid to servicing.
The T856 and T857 are both 60mm wide and each occupies a single space in a Tait rack
frame, which has the ability to accommodate up to seven standard modules.
1. Although capable of operating over the 400-520MHz frequency range, the T856 and
T857 have an 8MHz switching range (see Section 1.2.3 and Section 3.1).

Figure 2.3 T856/857 Microcontroller Block Diagram
Overall system control of the T856/857 is accomplished by the use of a member of the
80C51 family of microcontrollers (IC810). It runs from internal ROM and RAM, thus
leaving all 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) and deviation control EPOTS (IC220).
The main tasks of the microcontroller are as follows:
• program the synthesiser and EPOT;
• interface with the PGM800Win programming software at 9600 baud via the
serial communication lines on D-range 1 (PL100) & D-range 2;
• monitor channel change inputs from D-range 2;
• generate timing waveforms for CTCSS encoding;
• coordinate and implement timing control of the exciter/transmitter.

Figure 2.4 T856/857 Synthesiser Block Diagram
The synthesiser (IC740) employs a phase-locked loop (PLL) to lock a voltage controlled
oscillator (VCO) to a given reference frequency. The synthesiser receives the divider
information 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 from
the VCO buffer (fin) and the phase modulator (fref).
A reference oscillator at 12.8MHz (=IC700) is buffered (IC710 pins 3 & 4) and divided
down to 200kHz (IC730). This 200kHz square wave is then summed with the modulating audio and passed to an integrator (IC720 pins 9 & 8, Q710, Q720). This produces a
ramping waveform which is centred around a DC level determined by the incoming
audio. IC720 pins 5 & 6 perform as a comparator, ultimately producing a phase-modulated 200kHz square wave. This is followed by another phase shifting stage (IC720 pins
3 & 4, Q730, Q740), before being divided down to 6.25kHz or 5kHz within the synthesiser IC (IC740).
A buffered output of the VCO (Q795) is divided with a prescaler and programmable
divider which is incorporated into the synthesiser chip (IC740). This signal is compared
with the phase modulated reference signal at the phase detector (also part of the synthesiser 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, Q790) which produces a DC voltage between 0V and 20V to tune the VCO. This VCO control line is further filtered to attenuate noise and other spurious signals. Note that the VCO frequency
increases with increasing control voltage.
If the synthesiser loop loses lock, a pulsed signal appears at LD (pin 2) of IC740. This
signal is filtered and buffered by IC750 pins 1, 2 & 3, producing the Lock-Detect signal
used to shut off the power supply to the drive amplifier. IC750 pin 1 is at 20V when the
synthesiser is out of lock.

Two Point Modulation
M850-00
Frequency modulation occurs by modulating both the VCO input and the synthesiser
reference input. This process is called two point modulation and ensures a flat modulation response from 67Hz to 3kHz (2.55kHz for narrow bandwidth).
The PLL has a fast response time, allowing a Tx key-up time of <30ms. Because of this
fast response time the PLL sees lower modulation frequencies superimposed on the
VCO as an error and corrects for it, resulting in no modulation on the carrier. At modulation frequencies greater than 300Hz the loop cannot correct fast enough and modulation is seen on the carrier. The response of the loop to VCO modulation is shown by f2
in Figure 2.5 below.
To achieve low frequency modulation, the reference oscillator is also modulated so that
the phase detector of IC740 detects no frequency error under modulation. Thus, the
synthesiser loop will not attempt to correct for modulation and the audio frequency
response of the transmitter remains unaffected. The response of the loop to reference
frequency modulation is shown by f1 in Figure 2.5.

VCO
(Refer to the VCO circuit diagram in Part E.)
The VCO transistor (Q1) operates in a common emitter configuration, with an LC tank
circuit coupled between its gate and drain to provide the feedback necessary for oscillation. The VCO control voltage from the loop filter (IC750) is applied to the varicaps
(D1-D2) to facilitate tuning within an 8MHz band of frequencies. A trimcap (C6) is used
for coarse tuning of the VCO. The output from the oscillator circuit drives a cascode
amplifier stage (Q2, Q3) which supplies +10dBm (typically) to a further stage of amplification, Q5. This is the final amplifier on the VCO PCB, and delivers +20dBm (typically)
to the exciter drive amplifier.
A low level "sniff" is taken from the input to Q5 and used to drive the divider buffer for
the synthesiser (IC740).
The VCO operates at the actual output frequency of the exciter, i.e. there are no multiplier stages. It is modulated by superimposing the audio signal onto the control voltage
and by phase 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 and buffer amplifier are supplied from one +9V switched supply by Q540 via
the C multiplier (Q550, C530 on the T856 and C550 on the T857).
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 been
switched off. This is to allow the RF power circuits (both exciter and PA) to ramp down
in the correct manner before the VCO is switched off.

General
The audio processor comprises several link selectable circuit blocks which may be configured in a variety of combinations to suit individual requirements. The pre-emphasis
network and compressor may be linked individually or cascaded between either or both
audio inputs and the limiter.
Refer to Section 3.5.1 for linking details.
2.5.2
Audio Inputs
Two audio inputs are available: one from a 600 ohm balanced (or unbalanced) line, and
the other from a local microphone. The microphone signal is passed first to a pre-amplifier (Q210) and ultimately to a multiplexer (IC240), but in between may pass through
the compressor (depending on the linking details). The line transformer is also connected to the multiplexer and is disabled by the microphone PTT switch.
A third input for external CTCSS tones is also provided.

Keying Inputs
There are four ways to key the exciter:
• pulling the Tx-Key line low (pin 13 on D-range 1 [PL100]) at the rear of the set);
• pushing the "Carrier" button on the front panel - this will inhibit all audio;
• using the PTT button on the local microphone, disabling audio from the line;
• via the opto-key inputs (pins 11 and 12 on D-range 1 [PL100]) when electrical
isolation is required. This features a constant current sink (Q270) to ensure reliable activation of the opto-coupler (IC250) at low keying voltages.
2.5.4
Compressor (Automatic Level Control (ALC))
The input signal is fed via a current controlled attenuator (Q230, Q220) to a high gain
stage (IC230) from which the output signal is taken. This signal is passed to a comparator (IC230) which toggles whenever the audio signal exceeds a DC threshold determined by RV220. Thus, the comparator produces a square wave whose mark-space
ratio is determined by the amplitude of the audio signal. This square wave pumps up
the reservoir capacitor (C233) which controls the attenuator (Q230, Q220), thus completing the feedback loop.
The compression level is set by adjustment of the comparator threshold (RV220).
Note:
Although the high dynamic range of the compressor allows the use of very
low audio signal levels, such conditions will be accompanied by a degradation of the signal-to-noise ratio. Very low audio input levels should therefore be avoided where possible.
2.5.5
Outputs To Modulators
The output signal from the limiter (IC210, IC230) is summed with a CTCSS tone at a
summing amplifier (IC260). The signal is then low pass filtered (IC260) and split to supply the two modulators.
Since the VCO modulator is a true frequency modulator, its audio is simply buffered
(IC260). The reference modulator, however, is a phase modulator and its audio must
first be integrated (IC210).
It is vital that the audio levels to the modulators are accurately set, relative to each
other. Hence the inclusion of level adjustment in the reference modulator path. Once
set, adjustments to absolute deviation may be made only via the deviation digital pot.
(IC220 - adjustable via PGM800Win).

The T856 and T857 are designed to operate from a 10.8-16V DC supply (13.8V nominal).
A 5.3V regulator (IC630) runs directly from the 13.8V rail, driving much of the synthesiser circuitry. It is also used as the reference for a DC amplifier (IC640, Q630, Q620)
which provides a medium current capability 9V supply. The T856 has a regulator
(IC370) which produces 9V for use in the exciter and audio circuits.
A switching power supply (Q660, Q670) runs from the 9V supply and provides a low
current capability +20V supply. This is used to drive the synthesiser loop filter (IC750),
giving a VCO control voltage range of up to 20V.
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 audio processor, and microprocessor.

T856 Drive Amplifier & PA
M850-00
(Refer to Figure 2.1 and the exciter and PA circuit diagrams (sheets 3 & 4) in Section 6.2.)
The output power of the PA is maintained at a constant level via a power control loop
applied to the two-stage, wide band exciter amplifier (Q350, Q355). The forward and
reverse RF power levels are sensed via a dual directional coupler and detector diodes
(D440, D420 in the PA cavity). The detected DC signals are buffered (IC330 pins 3 & 5)
and then summed with the ’power control’ level and fed to the control integrator (IC350
pin 6). The output control voltage is buffered by Q310 and Q315, and applied to the collector of the wide band exciter amplifier.
Note:
Forward and reflected power signals are summed so that, under high
VSWR, the power control will turn the output RF level down.
To reduce the spurious output level when the synthesiser is out-of-lock, the Tx-Reg. and
Lock-Detect signals are gated to inhibit the PA control circuit and to switch off the RF
signal at the input to the drive amplifier. This is achieved by a PIN switch attenuator
(D340, D380, D360).
Cyclic keying control is provided by additional circuitry consisting of several time
delay, ramp and gate stages:
• Q325, IC350
power ramping
• Q355, Q325
Tx-Reg. and Lock-Detect gate
• Q335, Q340, Q345
delay and PIN switch drive.
This is to allow the RF power circuits (both exciter and PA) to ramp up and down in a
controlled manner so that minimal adjacent channel interference is generated during
the transition.
The output of the wide band amplifier is approximately 1W (+30dBm) for an input of
100mW (+20dBm) from the VCO, when the power control is set to maximum.
A temperature sensor (R481) is provided so that the RF output power can be reduced to
a preset level when a set temperature is exceeded. This is a protection circuit (IC350 pin
1, Q320) to prevent overheating, as the unit is not rated for continuous operation (refer
to Section 1.2.3 for duty cycle specifications).
#R517, #R518 and #R519 form an attenuator to provide good VCO/exciter isolation as
well as the correct exciter drive level.
The attenuator (#R395, #R396 and #R397) aids in producing the correct exciter drive
level to the PA over the three frequency ranges.
The RF output from the exciter is fed to the driver stage (Q410) and then to the final
(Q420). DC is fed to the final via a low pass filter with special low frequency decoupling. CV475 tunes the output matching across the entire band.

Introduction
When you receive your T856 transmitter or T857 exciter it will be run up and working
on a particular frequency (the "default channel")1. If you want to switch to a frequency
that is within the 8MHz switching range (i.e. ±4MHz from the factory programmed frequency), you should only need to reprogram the transmitter/exciter with the
PGM800Win software (refer to the PGM800Win programming kit and Section 3.2
below).
However, if you want to switch to a frequency outside the 8MHz switching range, you
will have to reprogram and re-tune the transmitter/exciter to ensure correct operation.
In this case you should carry out the short tuning procedure described in Section 3.4.
If you have carried out repairs or other major adjustments, you must carry out the full
tuning and adjustment procedure described in this section (except for Section 3.4).
3.2
Channel Programming
You can program up to 128 channel frequencies into the transmitter/exciter’s EEPROM
memory (IC820) by using the PGM800Win software package and an IBM PC. You can
also use PGM800Win to select the transmitter/exciter’s current operating frequency (or
"default channel").
If the transmitter/exciter is installed in a rack frame, you can program it via the programming port in the speaker panel. However, you can also program the transmitter/
exciter before it is installed in a rack frame as follows:
• by using a T800-01-0010 calibration test unit;
• via D-range 1;
• via D-range 2 (standard T800-03-0000 auxiliary D-range only);
• via SK805 (internal Micromatch connector).
If you do not use the T800-01-0010, you will have to connect the PC to the transmitter/
exciter via a module programming interface (such as the T800-01-0004).
For a full description of the channel programming procedure, refer to the PGM800Win
programming software user’s manual.
Note:
When an auxiliary D-range kit (D-range 2 - T800-03-0000) is fitted, you can
also select a channel with an external switch, such as the DIP switch on the
rack frame backplane PCB. Refer to Part C in the T800 Series Ancillary
Equipment Service Manual (M800-00-101 or later issue) or consult your
nearest Tait Dealer or Customer Service Organisation for further details.

Short Tuning Procedure
Use this procedure only if you want to reprogram the T856/857 to a frequency outside
the 8MHz switching range and do not intend to carry out any other major adjustments
or repairs.
3.4.1
Introduction
Reprogram the operating frequency as described in the PGM800Win programming kit (refer to Section 3.2).
Remove the top cover (nearest the handle).
Set up the test equipment as described in Section 3.3.
Set the links in the audio processor section as required (refer to Section 3.5).
3.4.2
Synthesiser Alignment
•
Connect a high impedance voltmeter to the long lead of L1 in the VCO (this measures the synthesiser loop voltage).
•
Key the transmitter by earthing the Tx-Key line.
•
Single Channel
Tune VCO trimmer C6 for a synthesiser loop voltage of
10V.
Multichannel
Tune VCO trimmer C6 for a synthesiser loop voltage of
10V on the middle channel.
If there is no middle channel, tune C6 so that the channels
are symmetrically placed around a loop voltage of 10V.
All channels should lie within the upper and lower limits
of 16V and 3V respectively.
Do not attempt to program channels with a greater frequency separation than the specified switching range of
8MHz.
3.4.3
Output Power Adjustment (T856 Only)
Connect an RF power meter to the output socket and key the transmitter.
Turn RV310 (power control) fully clockwise.
Tune #CV475 (output power trim) for maximum output power and check that this
is >30W.
Adjust RV310 for the required output power (between 5 and 25W).
Readjust #CV475 to reduce the supply current by up to 0.5A.

Two Point Modulation Adjustment
Note 1:
In this and following sections deviation settings are given first for wide
bandwidth sets, followed by settings in brackets for mid bandwidth sets ( )
and narrow bandwidth sets [ ].
Note 2:
Reference modulation and limiter adjustment are controlled by
PGM800Win. Electronic potentiometers (256 step) are used to allow channel-by-channel adjustment of deviation and two point modulation.
Note 3:
To optimise the modulation response across the switching range, repeat
steps 1-4 below for each channel that will be used (usually needed only for
data applications). In applications where the modulation response is less
critical (e.g. voice use only), carry out steps 1-4 below on the middle channel
and cut and paste the value to all other channels.
1.
M850-00
Inject an audio signal of 300Hz 1.5V rms (+5dBm) into the CTCSS input (D-range
1 (PL100) pin 8).
Key the transmitter by earthing the Tx-Key line.
2.
Adjust the output from the audio generator to obtain ±3kHz (±2.4kHz) [±1.5kHz]
deviation at 300Hz.
3.
Change the input frequency to 100Hz and adjust IC220 via PGM800Win “reference modulation” to obtain ±3kHz (±2.4kHz) [±1.5kHz] deviation (you can use
either the mouse or up and down arrow keys).
4.
Change the input frequency back to 300Hz.
Repeat steps 2 and 3 above until the deviations achieved at the two input frequencies are within 0.2dB of each other. You will need to do this at least four times.
5.
Sweep the audio between 50 and 300Hz for peaks.
Note:
A peak between 50 and 300Hz will indicate a fault condition, i.e:
or
- incorrect set-up
- modulation circuitry fault.
The specification window is ±1dB relative to 150Hz from 67 to 260Hz.
3.4.5
FM Deviation (Limiter) Adjustment
Note:
If the T856/857 will be used over the whole 8MHz switching range, you
must set the deviation for each channel. However, if the module will be
used on frequencies that cover only a 1MHz (or less) switching range, you
can set the deviation on the middle channel and use this value for all other
channels with the “fill” option in PGM800Win.

Tune VCO trimmer C6 for a synthesiser loop voltage of
10V.
Multichannel
Tune VCO trimmer C6 for a synthesiser loop voltage of
10V on the middle channel.
If there is no middle channel, tune C6 so that the channels
are symmetrically placed around a loop voltage of 10V.
All channels should lie within the upper and lower limits
of 16V and 3V respectively.
Do not attempt to program channels with a greater frequency separation than the specified switching range
(8MHz).
•
Check that the exciter output power is 1W ±300mW (T857 only).
•

necessary).
Turn RV310 (power control) fully clockwise.
Note:
Before the following measurement is taken, ensure the heatsink is at ambient temperature (20-25°C).
Measure and record the voltage (VL) at L481; perform this measurement at room
temperature so that the NTC (R481) is close to 25°C.
Key the transmitter by earthing the Tx-Key line.
Tune #CV475 until maximum power is obtained. Check that the power exceeds
30W.
Adjust RV310 (power control) to 25W.
Readjust #CV475 to reduce the supply current by up to 0.5A.

Audio Processor
3.9.1
Two Point Modulation
C3.11
The T856 and T857 utilise two point modulation to obtain a wide audio bandwidth
independent of the synthesiser loop filter response. This is achieved by simultaneously
frequency modulating the VCO and phase modulating the synthesiser reference frequency. The relative signal levels fed to the two modulators are quite critical and cause
interaction when setting up.
Both modulating signals require readjustment when the exciter is shifted in frequency
greater than the switching range (i.e. ∆F>±4MHz).
Note 1:
In this and following sections deviation settings are given first for wide
bandwidth sets, followed by settings in brackets for mid bandwidth sets ( )
and narrow bandwidth sets [ ].
Note 2:
Reference modulation and limiter adjustment are controlled by
PGM800Win. Electronic potentiometers (256 step) are used to allow channel-by-channel adjustment of deviation and two point modulation.
Note 3:
To optimise the modulation response across the switching range, repeat
steps 1-4 below for each channel that will be used (usually needed only for
data applications). In applications where the modulation response is less
critical (e.g. voice use only), carry out steps 1-4 below on the middle channel
and cut and paste the value to all other channels.
3.9.2
Modulator Adjustment
1.
Inject an audio signal of 300Hz 1.5V rms (+5dBm) into the CTCSS input (D-range
1 (PL100) pin 8).
Key the transmitter by earthing the Tx-Key line.
2.
Adjust the output from the audio generator to obtain ±3kHz (±2.4kHz) [±1.5kHz]
deviation at 300Hz.
3.
Change the input frequency to 100Hz and adjust IC220 via PGM800Win “reference modulation” to obtain ±3kHz (±2.4kHz) [±1.5kHz] deviation.
4.
Change the input frequency back to 300Hz.
Repeat steps 2 and 3 above until the deviations achieved at the two input frequencies are within 0.2dB of each other. You will need to do this at least four times.
5.
Sweep the audio between 50 and 300Hz for peaks.
Note:
A peak between 50 and 300Hz will indicate a fault condition, i.e:
or
- incorrect set-up
- modulation circuitry fault.
The specification window is ±1dB relative to 150Hz from 67 to 260Hz.

Note:
If the T856/857 will be used over the whole 8MHz switching range, you
must set the deviation for each channel. However, if the module will be
used on frequencies that cover only a 1MHz (or less) switching range, you
can set the deviation on the middle channel and use this value for all other
channels with the “fill” option in PGM800Win.

Visual Checks
Remove the covers from the T856/857 and inspect the PCB for damaged or broken components, paying particular attention to the surface mounted devices (SMD's).
Check for defective solder joints. If repair or replacement is considered necessary, refer
to Section 3 of Part A.
5.2
Component Checks
If you suspect a transistor is faulty, you can assess its performance by measuring the forward and reverse resistance of the junctions. Unless the device is completely desoldered, first make sure that the transistor is not shunted by some circuit resistance. Use a
good quality EVM (e.g. Fluke 75) for taking the measurements (or a 20k ohm/V or better multimeter, using only the medium or low resistance ranges).
The collector current drawn by multi-junction transistors is a further guide to their performance.
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.

Check the 13.8V (TP601) and 9V (TP602) supplies at their test points in the regulator compartment with a DMM.
Check the 5V (TP604) and 20V (TP603) rails at their respective test points in the
regulator compartment.
Check that Tx-Reg. (TP305 in the exciter compartment) comes up to 8.8V when the
exciter is keyed.
Check the +5V digital regulator output (TP607 in the regulator compartment).

VCO Locking
Key the exciter.
Using a DMM, monitor the VCO control voltage on the long lead of L1 on the
VCO PCB.
If the synthesiser is locked and the VCO aligned, the voltage at this point should
be between 3 and 16V.
If the VCO is not locked, refer to the synthesiser fault finding chart (Section 5.7.3).

Ensure that the VCO locks (refer to Section 5.4.2).
Connect the drive output to a power meter and key the transmitter.
Check that the exciter output power (SK310) is >1.5W.
Note:
If the synthesiser is out of lock, the lock detector (synthesiser IC740 and
comparator IC750) will prevent the RF signal from reaching the PA by
switching the supply to the exciter amplifier (Q350, Q355).

PGM800Win Generated Errors
The following errors are those most likely to occur using PGM800Win. Refer to the
PGM800Win software user’s manual for a complete list of error messages.
Channel Switch Set
The programmed default channel change was not accepted by the base station because a
channel is selected externally. Try turning the external channel switch off to change the
default channel in PGM800Win.
Synth Out Of Lock
The synthesiser received incorrect data, or the data was corrupted. Enter a frequency
within the VCO switching range, or tune the VCO.
Internal Error
Data could not be read from the base station due to an internal error. Check for shorts or
open circuits on the SDA, SCK, SYNTH and EPOT lines. The SDA, SCK and SYNTH
are normally high, and the EPOT is normally low.
Write/Read To An Unlinked Module
The link to the module does not exist. Undefined error.

To Replace The T856 PA Transistors
(Q410 & Q420)
Caution:
Failure to comply with the following procedure can result in failure of
the device due to poor heatsinking, or worse, can endanger the health
of the assembler if the beryllium oxide die carrier is smashed during
assembly.
Caution:
As the location of certain components in the PA is critical to performance, it is important that any components removed or disturbed are
refitted in exactly the same position.
Before attempting to remove a transistor, measure the distance
between the capacitors and transistor body to the nearest 0.5mm (measurement "A" in Figure 5.2) so that the capacitors can be replaced in
exactly the same position. These measurements are shown in Figure
5.2 for the 6LFL package, however the same procedure applies for the
SOE (stud) package.
Caution:
Do not apply too much heat or pressure to the PCB pads and tracks as
you may damage them or lift them from the PCB, causing permanent
damage to the transmitter.

How To Use This Parts List
The components listed in this parts list are divided into two main types: those with a circuit reference (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 within each group. Each component
entry comprises three or four columns: the circuit reference, variant (if applicable), IPN and description. A number in the variant column indicates that this is a variant component which is fitted only to the product type listed. Static sensitive devices are indicated by
an (S) at the start of the description column.
The miscellaneous and mechanical section lists the variant and common parts in IPN order. Where possible, a number in the legend
column indicates their position in the mechanical assembly drawing.
The Parts List Amendments box below lists component changes that took place after the parts list and diagrams in this section were
compiled. These changes (e.g. value changes, added/deleted components, etc.) are listed by circuit reference in alphanumeric order
and supersede the information given in the parts list or diagrams. Components without circuit references are listed in IPN order.

Description
Note: %D205 and %D210 are optional level limiting diodes for
special applications.
=R705 (47 ohm) and =SK710 are fitted in place of
=IC700 when an external frequency reference is used.
These two components are supplied with the auxiliary
D-range kits (T800-06-0000 & T800-06-0001).

Introduction
The T858 and T859 are FM base station power amplifiers designed for single or multichannel operation in the 400 to 520MHz frequency range. The output power capabilities are as follows:
T858 T859 -
10 to 60W
20 to 110W.
The older design T858/859 PAs (without RF power modules) comprise a broad band,
three stage drive amplifier whose output is split to drive two 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 two output stages fails, the transmitter can
still produce one quarter of its rated power.
The later design T858 PA (with RF power module) comprises a broad band, two stage
drive amplifier whose output is filtered before being fed to the output connector.
The later design T859 PA (with RF power module) comprises a broad band, two stage
drive amplifier whose output is split to drive two 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 two output stages fails, the transmitter can
still produce one quarter of its rated power.
VSWR and thermal protection are 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. Extensive use is
made of the latest surface mount technology.
Forced air cooling for the heatsink is provided on the T859 by a fan, which is activated
whenever the transmitter is keyed. Thermal sensors will also activate the fan automatically if the internal temperature reaches an unacceptable level.
The T858 has a width of 60mm and occupies a single space in a Tait rack frame, which
has the ability to accommodate up to seven standard modules. The T859 has a width of
120mm and occupies a double space.

Figure 2.2 T859 High Level Block Diagram
The T858 and T859 comprise a two-stage RF power amplifier with extensive control circuitry:
• the input stage consists of a single, three-stage RF power module which
increases the drive level to approx. 30W (40W typical);
• the final stage in the T858 is composed of a single transistor (Q216) which provides the rated output power; the final stage in the T859 is composed of two
transistors (Q216, Q217) whose outputs are combined to provide the rated output power.
Figure 2.1 and Figure 2.2 show the configuration of each of the main circuit blocks on a
functional level.

RF Circuitry
M850-00
(Refer to Figure 2.1, Figure 2.2 and the RF section circuit diagrams in Section 5.)
The driver stage of the T858 consists of a three-stage RF power module (#IC210) which
delivers 30-40W to the final amplifier (Q216). The output from the final is passed to the
antenna socket via the harmonic filter.
The driver stage of the T859 consists of a three-stage RF power module (#IC210) which
delivers 30-40W to the final transistors. The signal is split via a 3dB quadrature hybrid
(L241) and used to drive the two final amplifiers (Q216, Q217). The outputs from these
final stages are recombined by L240 and passed to the antenna socket via the harmonic
filter.
The diplexer presents the final amplifiers with a good load at harmonic frequencies,
which helps to achieve the expected harmonic attenuation in the output filter.
The directional coupler senses forward and reflected power, which is rectified (D205 &
D206) and passed to the control circuitry for metering, alarm and power control purposes.
Power control is via a series pass transistor (Q137 [Q128]), which controls the supply
voltage on the first two-stage of #IC210.

D2.7
Power Control
The DC voltages from the directional coupler representing forward and reflected power
are buffered by the two voltage followers, IC103 [IC100] pins 1, 2 & 3 and pins 12, 13 &
14. Their outputs are summed at an integrator (IC105 [IC110] pins 1, 2 & 3), which
drives the series pass control elements (Q135 & Q137 [Q124 & Q128]).
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 T858/859 can be limited by placing a ceiling on the
driver output power level using RV115 (accessible through the side cover). For example, if RV115 is set for a maximum output power of 50W, the range of adjustment using
RV109 (front panel power adjust) will be 20 to 50W.
Caution:
2.3.3
The driver power level clamp (RV115) is factory set to give a maximum
power output at room temperature of 60W for the T858 and 110W for
the T859. The unit may be damaged if this level is increased.
Thermal Protection
At excessively high temperatures, the output power will automatically reduce to a preset level (set by RV113), thus preventing the PA from overheating.
Ambient temperature within the PA is measured by a thermistor controlled voltage
divider (R168 [R177], R210) which applies a voltage to a comparator with hysteresis
(IC101 [IC105] pins 8, 9 & 10). This thermistor is located on the PCB in the low pass filter cavity.
Thermal protection is also provided for the RF power module to prevent the module
itself from overheating. This protection consists of a thermistor controlled voltage
divider (R203, R215 [R200]) which sets a voltage on a comparator with hysteresis (IC200
pins 1, 2 & 3). The thermistor is located on the module flange.
The output current from all comparators is summed into the power control network via
RV113 so that the power level to which the PA must turn down may be set.

T858/859 Circuit Operation
2.3.4
Forward And Reverse Power Alarms
M850-00
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).
IC103 [IC100] pins 5, 6 & 7 and pins 8, 9 & 10 form comparators with thresholds
adjusted via RV101 (forward power) and RV105 (reverse power) respectively. The
inputs are from the forward and reverse power signals from the directional coupler,
buffered by IC103 [IC100] pins 1, 2 & 3 and pins 12, 13 & 14. Thus, the power levels at
which the forward and reverse power alarms are triggered are defined by RV101 and
RV105 respectively.
2.3.5
Forward And Reverse Power Metering
Forward and reverse power signals from the two IC103 [IC100] buffers are available for
metering purposes. The output currents are adjustable via RV103 (forward power) and
RV107 (reverse power).

Comparator IC105 pins 12, 13 & 14 are set to switch at heatsink temperatures greater
than +90°C or RF power module flange temperatures greater than +110°C, and pins 1, 2
& 3 at temperatures less than -10°C.
A logic AND function is applied to the comparator outputs by Q111 and Q112, thereby
turning on the fan unconditionally (via Q113 and Q114) if the heatsink temperature
exceeds +90°C or the module flange temperatures exceed +110°C.
A logic OR function is applied to comparator IC105 pins 12, 13 & 14 and Tx KEY signals,
thereby turning on the fan when the transmitter is keyed and the temperature is
between -10°C and +90°C (or +110°C for the module flanges).
If the temperature drops below -10°C, Q112 is turned off, preventing Q111 from activating the fan.

Setting The Output Power
Caution:
If the high temperature shutdown power level has not yet been set or is
unknown, check that the unit does not overheat while setting the output power.
Note 1:
Cables and connectors can easily cause a power loss of several watts if either
too long or poorly terminated. Always use the shortest possible leads (or
connectors instead of leads) between the T858/859 and power meter set-up.
Note 2:
You will need appropriate extension leads if you wish to carry out the
adjustment procedures with the T858/859 withdrawn from the rack in the
latched position. Alternatively, disconnect and withdraw the T858/859 and
reconnect it behind the rack.
Note 3:
The actual power used may be limited by regulatory requirements.
Connect the exciter output to the PA input via a thru-line wattmeter with a 5W
full scale reading. Special BNC/N leads will be required.
Ensure that PL110 pins 11-12 and 13-14 are linked, and all other pins are not

D3.5
Check that the power output exceeds:
T858 T859 -
Note:
60W
120W.
The side cover access hole for the driver power clamp (RV115) is covered
with a tamper-proof sticker. The clamp has been factory set to 60W (T858)/
110W (T859) maximum output power and should not normally need
adjustment. If the output power level is low, check that the high temperature shutdown circuit has not activated by verifying that IC101 [IC105] pin 8
is low.
Adjust RV115 to reduce the maximum power output to:
T858 T859 -
60W
110W.
Adjust RV109 [%RV109] to set the power output to the required level (e.g. 50W for
the T858, 100W for the T859).
3.5
High Temperature Shutdown Power Level
Set RV109 [%RV109] (front panel power control) to the required output power.
Simulate high operating temperatures by placing a shorting link on PL110 pins 5-6
(do not use either of the links from PL110 pins 11-12 or 13-14 to do this).
Adjust RV113 (shutdown power level) for an output power of:
T858 T859 -
20W
40W.
Remove the shorting link from PL110 pins 5-6 to return the PA to normal operation.

Remote Forward Power Meter Calibration
If a remote meter is connected, adjust RV103 (forward power meter calibration)
for the remote reading to agree with the RF power meter reading.

Remote Reverse Power Meter Calibration
If a remote meter is connected, connect a 50 ohm 3dB pad (with the output open
circuit) to the PA output.
Apply RF drive and Tx-Key.
Adjust RV107 (reverse power meter calibration) for a quarter of the forward
power reading.

3.8.1
Forward Power
M850-00
Power up the T858/859 and adjust RV109 [%RV109] (front panel power control)
so that the output power is at the alarm level required (e.g. 40W if the T858 normally operates at 50W).
Adjust RV101 (forward power alarm set) so that the forward power alarm LED
lights.
Check the alarm level setting by adjusting the power up and down and observing
the alarm LED. A few watts hysteresis can be expected.
Readjust RV109 [%RV109] for the normal operating level.
Note:
Remote indication is available at pin 3 of D-range 1.
3.8.2
Reverse Power
Power up the T858/859 and adjust RV109 [%RV109] (front panel power control)
for the normal operating power level.
Place a known mismatch of the required value (e.g. 3:1 VSWR) and adjust RV105
(reverse power alarm set) so that the reverse power alarm LED lights.
Example:
A VSWR of 3:1 can be simulated by connecting an unterminated 3dB pad
(50W) to the PA output. This will result in a return loss of 6dB.
Note:
Remote indication is available at pin 4 of D-range 1.

T858/859 Fault Finding
Caution:
This equipment contains CMOS devices which are susceptible to damage from static charges. Refer to Section 1.2 in Part A for more information on anti-static procedures when handling these devices.
The following test procedures and fault finding flow charts may be used to help locate a
hardware problem, however they are by no means a complete fault finding procedure.
If you still cannot trace the fault after progressing through them in a logical manner,
contact your nearest Tait Dealer or Customer Service Organisation. If necessary, you
can get additional technical help from Customer Support, Radio Systems Division, Tait
Electronics Ltd, Christchurch, New Zealand (full contact details are on page 2).
Note:
Where the same component has different circuit references in the T858 and
T859, in this and following sections the T858 circuit reference is given first,
followed by the T859 circuit reference in brackets, e.g. Q137 [Q128].
Refer to Section 5 where the parts lists, grid reference index and diagrams will provide
detailed information on identifying and locating components.

Visual Checks
Remove the side cover from the T858/859 and inspect the PCB for damaged or
broken components, paying particular attention to the surface mounted devices
(SMDs). Also check for defective solder joints.
Refer to Section 4.7, Section 4.8, Section 4.9 and Section 3 of Part A for more details
on repair and replacement of components.

Shorting Links
There are seven shorting links on PL110 in the control section circuitry, as described in
the table below. Ensure that these links are set as standard before starting and after
completing the adjustment procedure.
Link Pins

Not used.
5-6
not linked
Pins 5-6 are provided for simulating high
operating temperatures during initial
adjustment. Bridging this link shorts out
R215 [R200] and R210 (NTCs), thus turning
on the thermal protection circuitry. They
should not be linked for normal operation.

Pins 11-12 and 13-14 are provided for factory testing only. The PA will not function
correctly if these settings are changed.

Function
Component Checks
If you suspect a transistor is faulty, you can assess its performance by measuring the forward and reverse resistance of the junctions. Unless the device is completely desoldered, first make sure that the transistor is not shunted by some circuit resistance (e.g. a
base choke). Use a good quality EVM (e.g. Fluke 75) for taking the measurements (or a
20k ohm/V or better multimeter, using only the medium or low resistance ranges).
Caution:
Before operating the PA, replace any RF base chokes removed while
making measurements.
The collector current drawn by multi-junction transistors is a further guide to their performance.

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.

DC Checks
Note:
No RF power is to be applied during these checks.
Check that +13.8V is present on the collectors of Q216 (T858) or Q216 and Q217
(T859). Make this measurement when the transmitter is not keyed.
Check that approximately 8-13.8V is present on pin 2 of #IC210 (the level is
dependent on RV115 being set to maximum).
Check that +13.8V is present at pin 4 of IC100.
Check that approximately +12V is present at pin 8 of IC110 (the level is dependent
on RV115 being set to maximum).
Check that +7.0V is present at the output of regulator IC130.

Caution:
Failure to comply with the following procedure can result in failure of
the device due to poor heatsinking, or worse, can endanger the health
of the assembler if the beryllium oxide die carrier is smashed during
assembly.
Caution:
As the location of certain components in the PA is critical to performance, it is important that any components removed or disturbed are
refitted in exactly the same position.
Before attempting to remove a transistor, note the position, type and
value of each capacitor. Measure the distance between each capacitor
and the transistor body to the nearest 0.5mm (measurement "A" in Figure 4.2) so that it can be replaced in exactly the same position. These
measurements are shown for the T858, however the same procedure
applies for the T859.
Caution:
Do not apply too much heat or pressure to the PCB pads and tracks as
you may damage them or lift them from the PCB, causing permanent
damage to the PA.
