Introduction
The T889 is an FM base station power amplifier designed for single or multichannel
operation within the frequency range 800 to 870MHz. 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 reliability, 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 automatically 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.

Figure 2.1 High Level Block Diagram
The T889 comprises a three stage RF power amplifier with extensive control circuitry.
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 recombined 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).

2.3.1
2.5
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 outputs are summed at an integrator (IC1 pins 8, 9 & 10), which drives the series pass control 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 preset 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.

Comparator IC3 pins 8, 9 & 10 are set to trigger at heatsink temperatures greater than
+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.

Component Replacement
3.3.1
Leaded Components
M889-00
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 circular motion.
Start the suction and continue the movement until 3 or 4 circles have been completed.
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 soldering iron on the tip of the desoldering iron (this may require some additional 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.

To Replace PA Transistors
M889-00
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.
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.
Be sure to measure between the transistor body and the tabs (not the body)
of the capacitors.
Note:
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 screwdriver.
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.

To Remove The PCB From The Heatsink
M889-00
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 transistors.
To replace the PCB, reverse the order of removal, taking care that the wiring is correctly 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 equivalent.

Initial Connections
Connect the PA to a power supply, an output RF load and a power meter as
detailed below:
power supply rating
RF load
>30A
>150W.
Provide a keyed RF drive at the required frequency.
Connect the drive source key line to pin 12 of the external connector.
Set RV69 (temperature shutdown) fully anticlockwise to avoid RF power cycling
between the levels as set by RV63 and RV74.
4.2
RF Alignment
Set RV63 (power control) fully clockwise.
Key on the drive source (the power output should exceed 100W).
Adjust RV69 (driver power level) until the output power drops to 100W.
Adjust RV63 to reduce the power output to the required level (e.g. 90W).
4.3
High Temperature Shutdown Power Level
Set RV63 (power control) to the required output power.
Earth pin 12 of IC1 (the pad at NTC R72 is convenient).
Adjust RV74 (shutdown power level) for an output power of 20W.
Remove the earth from pin 12 of IC1.
4.4
Low Forward Power Alarm
Set RV63 (power control) to the output power at which the alarm is required to
activate.

Fault Finding
M889-00
5.1
Fault Finding
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 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 Electronics Ltd, Christchurch, New Zealand.

Visual Checks
Remove the cover from the T889 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 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 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.
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.

Rack Mounting
The T889 PA is designed for use in a standard 483mm rack frame using the supporting
guide rails supplied with the unit (refer to Figure 6.1).
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).

Introduction
PCB Identification
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 letter 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 description of the part.
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 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 component grid reference index has been provided. This index lists the components and pads in alphabetical 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 numbers 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

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.
