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.
