Classification: CPC H | IPC H

Claim 3:
4. A control circuit comprising:
a front-end module (FEM) coupled to an RF cable, the FEM comprising a low-noise amplifier (LNA); and
an automatic gain control (AGC) circuitry coupled to the FEM, the AGC circuitry comprises an amplifier, wherein the AGC circuitry:
receives a first radio frequency (RF) signal comprising a first portion and a second portion, wherein the first portion comprises one or more symbols and the second portion comprises one or more symbols;
amplifies the first portion to generate a first portion of an output signal;
compresses the second portion to obtain a second portion of the output signal; and
sends a control signal to cause the FEM to change a gain state value of the LNA from a first value to a second value based on a comparison between a voltage of the output signal and a reference voltage.
