Intelligent gain control in an on-frequency repeater
First Claim
Patent Images
1. A method for controlling a gain of an on-frequency repeater, the method comprising steps of:
- receiving a broadband radio frequency (RF) signal within a signal path of the repeater;
determining a power level of a selected narrowband signal within the broadband RF signal; and
controlling gain of the signal path in accordance with the power level of the narrowband signal.

Abstract
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.
