Intelligent gain control in an on-frequency repeater

摘要

An intelligent gain controller (IGC) for an on-frequency repeater includes a broadband gain controller (GC) for amplifying a broadband radio frequency (RF) signal within a broadband signal path of the repeater. A narrowband receiver isolates a narrowband signal within the broadband RF signal. A processor determines a power level of the narrowband signal, and controls the gain of the broadband GC in accordance with the determined power level.
