AGC LED: This red led illuminates when the transmitted power is equal or higher
than the composite power (factory preset at +24 dBm and DL).
AGC ON/OFF switch: Turns on the automatic power control.

lock Diagram DescriptionB
The CBDA Downlink path receives TX signals from base station amplifies them
and transmits them to the subscriber. The CBDA Uplink path receives RX
signals from the subscriber amplifies them and transmits them to the base
station. Two quad filter assemblies frequency separate the signals to the proper
amplifying path and isolate the two signals.
Each path has two amplifiers; a low noise amplifier (LNA) and a high power
amplifier. The low noise amplifier has a 30 dB step attenuator, which is used to
set the repeater gain.
The power amplifiers in the CBDA have an AGC option switch. They also have a
Power LED lamp that illuminates when the output power has reached the preset
power limit.
