Abstract
The present invention concerns a system for controlling gain when time-sharing a tuner in a frequency diversity receiver. Two radio-frequency automatic gain control (RFAGC) filter capacitors are used, each capacitor corresponding to one of the currently utilized frequencies in the frequency diversity scheme. The capacitors are switched in tandem with the tuner frequency selection. This allows the capacitor associated with a tuned frequency to retain the RFAGC voltage until the tuner returns to that frequency.
