SLR 5000 Series Power Amplifier

4.1

Description

The Power Amplifier Module is described in this section. A general description, identification of inputs

and outputs and functional theory of operation are provided. The information provided is sufficient to

give service personnel a functional understanding of the module, allowing maintenance and

troubleshooting to the module level.

4.1.1

General Description

The Power Amplifier (PA) is a forced convection-cooled RF power amplifier. It accepts a low-level

modulated RF signal from the Exciter Module, and amplifies it for transmission via the site transmit

antenna port. The PA is non-linear, and is therefore used for Continuous Wave (CW) applications only.

The output power is continually monitored and regulated by a feedback and control loop, with a power

output control voltage being generated by the transmitter control circuitry located on the PA. All

configuration and control signals are connected to the modem module via the flex connected between

the modules.

NOTICE: The power amplifier cooling fan is replaceable and external to the power amplifier

itself. See SLR 5000 Series Maintenance and Disassembly/Reassembly on page 97 for

replacement details.
