- The switch on the RF amplifier enables the AGC function. If the AGC is disabled then the amplifier gives maximum gain.
- MGC: The RF gain of the BDA can be reduced by about 15 dB using the continuos trimmer on the amplifier. The RF gain is at maximum when the trimmer is at anti-clockwise direction. To reduce the gain, turn the trimmer clockwise using a screwdriver. Turning
- The AGC and MGC functions for the uplink path are reached by opening a small cover located on the DBA side adjacent to the Mobile antenna port. For the downlink path the window is located on the side near the Base antenna port.
- Note: The BDA is shipped with the AGC switch in the OFF position and maximum RF gain.
