This 2Watt, 821-869 MHz, class A Power Amplifier Module provides a nominally
51 dB of gain. It has 30 dB of gain adjustment range, which can be varied
electronically thru the front panel RS232 connector. Additionally, the module
has an internal Automatic Level Control (ALC) circuit, which can be set to limit
the maximum power level produced by the BDA. This module has an on board
RISC processor that provides optional alarming/status monitoring and
communications capabilities. The same module design is used for both the
Downlink and Uplink amplifier.
The amplifier module contains high reliable RF parts to provide a long trouble-
free operating life. In the unlikely event of failure, the entire amplifier module
should be replaced.
