CHAPTER 1
GENERAL DESCRIPTION
INTRODUCTION. This chapter contains a description of the equipment supplied, equipment required but not
supplied, storage data, and recommended tools and test equipment.
EQUIPMENT DESCRIPTION. The PA-SOSOA linear power amplifier (figure 1-1) is a solid state unit that
provides 1 kilowatt power amplification of RF signals between 1.6 and 30 MHz. The unit contains 4 independent
power amplifier (PA) modules. Ifone or more ofthe PA modules fail, the unit will still opelate with reduced power
out.
The front panel contains a PWR LED with each PA module containing an individual PWR and FLT LED, and a
multifunction display. Input power to the PA-SOSOA is derived from a separate +28V DC power supply providing
five separate +28V DC outputs. The CCl PS-7130A meets this requirement and is recommended for optimum
performance. Four independent modular PA modules provide the four stages of amplification. Each PA module is
identical and interchangeable. When an individual PA module's gain is less than +10 dB, the circuitry turns on the
FLT LED. The individual module can then be removed and replaced.
The rear panel contains connectors for the n-ansmitter/exciter low power RF input, high power RF output to the
antenna, remote control input, DC power and signal input, and a ground lug.
Four internal fans per PA module provide cooling across the heasink of the unit.
Refer to table l-l for specifications of the equipment,
EQUIPMENT FURNISHED. Table l-2 lists the items furnished, items required but not supplied, and
optional items.
1-4
STORAGE DATA. Refer to Chapter 7 for storage data.
1-5 TOOLS AND TEST EQUIPMENT. Table 1-3 lists recommended tools and test equipment for operational
1-8
level maintenance. There are no special tools or test equipment required.
SAFETY PRECAUTIONS. Safety precautions are presented in this manual preceded by the word
WARNING or CAUTION just before the point where the hazard is likely to be encountered. Warnings and cautions
are defined as follows:
Refers to a procedure or practice that, if not correctly followed,
could result in injury, death, or long term health hazard.
Refers to a procedure or practice that, if not correctly followed,
could result in damage to, or demotion of equipment.

CHAPTER 4
GENERAL THEORY OF OPERATION
lNTRODUCTlON. This chapter contains a block diagram description of the PA-SOSOA linear power
amplifier. The following paragraphs describe operation of the PA-5050A (see figure FO-Z).
GENERAL THEORY OF OPERATION.
4~2.1 magma Power is applied to the rear panel of the unit on connector”. Five individual +28V
DC inputs are required to operate the equipment. Four of the +28V inputs at 25 amperes are applied directly to
each of the four PA modules and their associated fans. The other +28V input at I l amperes is applied to the
Attenuated Pre-driver module, PA Driver module. bowpass Filter board, and a DC-DC converter on the
Filter/Driver board that produces +lZV, ~12V, and +5V DC voltages for the internal circuits.
4-22 mm The controller board provides all necessary control signals for the unit using the external
RS-485 remote control bus and internal sensors. The controller board receives control signals on the bus from the
Transminer/Fatciter on rear panel connector 15, and provides status and data information on the fi'ont panel display.
Control signals to/fi'om the inlemnl circuits are descn'hed as follows:
WA A’lTN Analog signal used to {me tune the attenuation (0 - 2.0 dB) of the Attenuator Pre-Driver
A l N (0-3) Digital outputs to course tune the attenuation (0 - 30 dB, in 2 dB steps) of the Attenuator Pre-
Driver via Filter/Driver circuits
LP (0-2) Digital outputs to select correct lowpass filter for the selected frequency

4:2.3 QM The Display board contains a liquid crystal alphanumeric display that provides an indication of
forward power, reflected power, attenuation and frequency. When the front panel DISPLAY STATUS switch is
pressed, the display shows the alternate information,
4-24 M The Filter/Driver board contains four separate circuits:
DC-DC Convener - converts the +28VDC irnput power to +12, -l2, and +5 VDC for use by the irntemal circuits.
Filter Driver - contains logic drivers for signals From the Controller board to the Low Pass Filter board, PA Driver
module, and PA modules.
MUX - provides the interface between the PA Modules and Controller board. Also provides LED at signals for the
external power supply.
Detector - converts the sampled RF from the iii-Directional Coupler to DC levels proportional to the forward and
reflected power applied to the antenna These DC volanges are then applied to the Controller board as FWD DET
and REFL DET signals. It also provides the SHUTDOWN signal to tile Anenuator/Pre—Driver if excessive
forward or reflected power is sensed.
4-25 AM The RF [N signal firm! the transmitter/exciter enters the PA-SOSOA on rear
panel connector J 1 where it is applied to the Anenuator/Pre—Driver board. “Hie signal is attenuated and then
amplified to provide the correct drive level for tlne PA modules to maintain the 1000 Watts of output power.
Attenuation controls from the Controller board, through the Filter/Driver board, determine the amount of
attenuation to be applied to the signal based on the forward and reflected output power. The four digital A‘iTN
lines (0-3) provide coarse attenuation through the Filter/Driver board from O to 30 dB in 2 dB steps, while the
analog VVA A‘l'I'N signal provides the fine attenuation control continuously from 0 to 2.5 dB. If the Detector
circuits on the Filter/Driver board sense excessive forward or reflected power the SHUTDOWN signal adds up to
18 dB of attenuation control as required.
4-2.6 EAflliKeLMMl-lle. The signal from the Attenuator/Pre-Driver is then applied to the PA Driver module for
amplification. The DRIVER GATE signal enables the amplifier when the transmitter/exciter is keyed. A thermal
switch opens, removing +28 VDC input voltage to disable the PA Driver in case Oran over temperature condition.
4-27 §plittgr Magulg. The RF signal from the PA Driver module is then applied to the Splitter module. The
Splitter module provides four equal RF outputs to each of the four FA modules.
4-23 EAMHLE. The four PA modules are identical and interchangeable. Each PA module amplifies the signal
providing up to 300 Watts of output power to maintain 1000 Watts output. The PAGATE signal enables each
amplifier when the transmitter/catcher is keyed. Power variations are compensated for by varying the attenuation of
the input drive signal to all four modules.
To prevent overdrive damage to the other PA modules, a low-gain detector circuit in each PA module activates
when the gain of the module drops to leu than +10 dB. The detector circuit lights the red FLT LED on the front
panel of the module. At the same time, a FAULT signal is sent to the MUX circuit on the Filter/Driver board. The
MUX circuit then sends the FAULT signal to the microprocessor on the Controller board. In response, the
microprocessor, through the Filter/Driver board, causes an additional -6 dB of attenuation to be applied by the
Attenuator/Pre-Driver to the RF input of the PA-SOSOA. When the gain is +10 dB or greater the detector resets,
the FLT LED goes off, and normal drive is restored with modulated signals, the FLT LED may momentarily
flicker.
A green PWR LED on the front of each module lights when power is applied to the module. If there is an over
temperature condition, a thermostat switch in the module opens, and the +28V used to drive the PWR LED is
removed. Simultaneously a TEMP sensor signal is sent to the MUX circuit on the Filter/Driver board. The MUX
then sends the TEMP signal to the microprocessor on the Controller board. In response, the microprocessor,
through the Filter/Driver board, causes an additional 6 dB of attenuation to be applied by the Attenuator/Pre-Driver

to the RF input of the PA-SOSOA. This reduction of drive to the PA modules causes the temperature to drop.
When the PA module cools down sufficiently, the thermostat switch closes The PWR LED lights, and normal

Each PA module has a VOLTAGE SENSE line that is sent to the individual external power supplies. These
signals allow each external power supply to vary the input voltage to compensate for line loss and load variations.
If the PS-7130A is used, each input voltage is adjusted based on the VOLTAGE SENSE signal,

Section II. CORRECTIVE MAINTENANCE
TROUBLESHOOTING.
5-5 1 MEMMMMK Certain assumptions are made concerning the troubleshooting approach as
applied to the unit as follows:
1. All poinHo-point wiring is correct Therefore, no malfunction is the result of a wiring (or cable connector) fault.
NOTE
Suspected failure of cables or connectors require
visual inspection and continuity tests using the
appropriate diagram See F0-2 for interconnecting
diagram.
2, Malfunctions are non-interactive. cmh symptom of a problem is caused by a single malfunction and no
additional failures occurred during the troubleshooting process
3. Multiple faults can be isolated if they are non-interactive.
4. Preventive maintenance has been performed (Section 1).
5-52 mm Refer to chapter 4 for the block diagram description. Equipment
troubleshooting should be performed in the following order;
1. Fault identification
2. Initial checks.
3. LED interpretation
4. Module replacement.
5. Voltage/continuity checks.
Refer to the following paragraphs for details:
5-521 mm A fault is usually indicated by the front panel display, and/or a PWR LED not lit,
and/or a FLT LED lit on one of the PA modules.
5-512 Mm Before detailed troubleshooting, check that the green PW'R LED on the front panel of each
PA module is on, the FLT LEDs are on“, and power is applied to the equipment ( PS-7130A S] on (up)). If one or
more of the PWR lamps are off, and power is applied to the PA-SOSOA, ensure that +28V DC input voltages are
correct. Check all cables and connectors on the rear panel, and check the input RF drive from the exciter.
If one or more PWR LEDs are off, but the master power LED is on, an overheat condition may exist. Unkey the unit
and wait five minutes, then try again. If the problem persists, remove and replace the affected module(s)l
5-523 WEmh PA module contains a PWR and FLT LED. Table 5-1

‘ NOTES:
If a PWR LED remains off for more than a few seconds, or the FLT LED lights, the fault is usually in the indicated
PA module. Remove power from the unit and remove and replace the suspect PA module with one from another slot
to confirm the faulty module,
if multiple PWR LEDs are off, excessive temperature may be the problem. Check proper operation of the couling
fans and/or the ambient temperature.
Ifna power LEDs are off, and no FLT LEDs are lie check the front panel display for correct VSW'R. The pmblem
may be in the antenna system. if the fault cannot be isolated using the above analysis, the fault is probably in the
chassis or in a non-monitored function in a PA module. Also check that the tnnsmitter/exciter drive power is
sufficient.

5-533 Calibrggjgn
The PA-5050A (PA) has a calibration function added for calibrating the PAP] command afler a power amplifier
module, driver module, or T-4150/80 has been replaced, The calibration must also be performed afier an upload
of the sofiware and the fust time the system is operated.
The calibration requires an RF input at +24dBm, the low-pass filter selected to match the frequency, and the PA is
terminated with a 500 resistive load with at least a IOOOW rating. The calibration will complete within 5 seconds.
To prepare a controller that has been previously calibrated, the flash must be cleared. There are two methods to
accomplish this:
I. Change the power switch to the ON position while pressing the DISPLAY button on the horn of the PA.
When the display says "PWR OFF TO ABORT", release the button. The display will change to ”PRESS T0
ERASE". Press the DISPLAY button again to erase the calibration values. When the erase operation is
complete the display will show "10000000 -1" for about two seconds. The PA is now ready for calibration. If
the power is turned off before the second press, the erase will not occur.

Attach a T4150/80 to the RF in and control connectors. Set PAPOW to [00 Watts using the sofikeys on the
T4180/50. Key the transmitter.
Attach a signal source at +24dBm to the exciter RF ln connector, an R8422 controller to either Remote
Control connector, a dummy load capable of sinking at least IOOOW for 10 seconds to the ANT connector,
and a power meter in series with the dummy load RS422 commands will be sent using the format shown in
table 3-2 in the PA5050A Technical Manual. Set the PA to the frequency of the input signal source using the
PAF command. Short pin 1 of the unused Remote Control connector to chassis ground. Send the PAH
command through the R5422 controller. Afier the power meter reading stabilizes at approximately l20W,
remove the ground from pin 1 of the Remote Control connector.
Attach a signal source at +24dl3m to the exciter RF in connector, an RS422 controller to either Remote
Control connector, a dummy load capable of sinking at least [000W for IO seconds to the ANT connector,
and a power meter in series with the dummy load. RS422 commands will be sent using the format shown in
table 3-2 in the PASOSGA Technical Manual. Set the PA to the frequency of the input signal source using the
PAP command. Send the PT 1 command to turn the PA to transmit. Send the PAPI command. After the
power meter reading stabilizes at approximately l20W, send the PTO to unkey the PA.
The alternate receive display on the PA shows ATTEN, which should he a value between 2200 (-22dB) and l200
(-lZ dB) after the calibration is complete.
NOTE
lftlte amplifier is keyed by
means of the PT] command, the
PT} must be sent before the
PAPl.
554 WWW If the failed module cannot be isolated using the initial check or LED
interpretation, remove and replace the unit. Further isolation should be performed at the factory by checking
voltages and continuity ofwires in the chassis.
When the top cover is removed, high voltage may be present at the
rear panel POWER connector, and the chassis terminal block. Use
caution when working in these areas.
Do not key the PA-SOSOA with the top cover
removed, RF burn injury may occur,
Using a no. 2 Phillips screwdriver, push down, and turn all captive fasteners on the top cover l/4 tum
counterclockwise.
Remove the top cover.
Voltages are checked at various locations in the equipment using a voltmeter (see figures FO-2, FO-3 and
F0—4).

4. Some voltages my be checked on the rear panel connecton. Refer to chapter 2 for pin—outs offliese
connectors. Some voltages may be checked by removing the module where the signal in question terminm,
and checking the voltage at the connector in the chassis.
Remove the +28V DC input voltages before performing continuity checks. Damage in
the test equipment may occur if continuity checks are performed with input voltages
applied to the equipment.
5. Using an ohmmeter, perform continuity checks using FO-Z.
