February 28, 2003
XPA200-7984-I-OPT1, X-Band SSPA Installation and
Operation Manual, Rev. 2

Attach these pages at the beginning of the
manual.

Change Specifics:

1. Section 3.3.2.1 should be amended to include (amendments or
changes in bold):

. . .
EXT mute on from external J4 control (see section 1)

ON muted by M&C control or via remote control

2. Section 5.8.2.2 should be amended to include (amendments or
changes in bold):

. . .
Confirmation: >DEV/MUT_xxx’cr’lf’]

Note: On Status queries, the ‘MUT’ command may also return EXT
(mute on from external J4 control) or INH (mute on or inhibited by
Mitec 2723B via J5).

3. Section 5.8.3.1 should be amended to include (amendments or
changes in bold):

. . .
TX_nnn’cr’ Transmit – ON/OFF/EXT/INH
. . .

Filename: XPA200-7984-I-OPT1_Errata_a.doc 1

4. Section 5.8.3.5 should be amended to include (amendments or
changes in bold):

. . .
+10_2_xx’cr’ +10 PS#2 Fault

SHTD_xx’cr’ Thermal Shutdown

. . .

Note: A temperature fault is indicated if the unit is less than ­20C or more than 85 degrees C. This creates a summary fault and
will cause the unit to mute itself and switchover to the back-up
unit. However, the 10V supply to the FET transistors will remain
on until the unit reaches the thermal shutdown temperature of 90
degrees C or above. For protection reasons, the unit will
shutdown the 10V supply to the power transistors at temperatures
at or above 90 degrees C.

Introduction

1.1 Scope

This manual provides instructions on the installation,
operation and maintenance of the XPA200-7984-I X-Band Solid State
High Power Amplifier manufactured by COMTECH COMMUNICATIONS Corp.

1.2 Functional Description

The XPA200-7984-I X-Band High Power Amplifier (SSPA) is
designed for use in communication systems, or in satellite up­link data systems. The SSPA operates over the RF input frequency
range of 7900 to 8400 MHZ. The RF power output is 53.0 dBm
minimum at 1 dB compression. A functional block diagram is shown
in Figure 1-1.

The SSPA is designed to be hard mounted in a standard 19­inch rack or cabinet, or to be rack mounted using COMTECH slide
mechanisms provided with the SSPA to allow it to be serviced
without its removal from the rack. Two internally mounted
exhaust fans are mounted on the chassis for cooling. An AC power
connector, with an on/off switch, is located on the rear on the
chassis.

All operator controls, indicators and displays for local and
remote operation as well as the RF Input and Output sample test
ports are located on the front panel of the SSPA. Connectors for
the external interface connections are located on the rear of the
SSPA chassis.

Variable Phase Combiner and

Redundant Switching System

2.1 Unpacking and Inspection

This section is intended to give a brief explanation on how to
setup and operate two Comtech XPA200 SSPAs with the Mitec 2723B
Variable Phase Combiner and Redundant Switching System. More detailed
explanations on operation of the SSPA are contained in later sections
of this manual. More detailed operating instructions for the Mitec
Combiner and redundant switching system can be found in it’s
associated manual.

Inspect the shipping container for damage. The shipping
container and packing materials should be retained for possible re­shipment. Check to determine that all parts, materials and
documentation have been shipped with the SSPA. The SSPA should be
inspected for possible damage, and then tested for proper operation.

If the shipment is incomplete, or there is mechanical damage, or
the SSPA does not operate properly, notify the COMTECH Customer
Service representative immediately. If there is damage to the
shipping container, notify the carrier, and retain all shipping
materials for inspection by the carrier.

2.2 Rack Mount Installation
