Classification: CPC H | IPC H

Claim 0:
1. A system comprising:
a radio frequency (RF) cable;
a communication device comprising:
a radio coupled to a first end of the RF cable; and
a compensator circuit coupled to a second end of the RF cable, the compensator circuit comprising:
a front-end module (FEM) circuit coupled to the second end of the RF cable; and
an RF detector circuit coupled to the second end of the RF cable, wherein the RF detector circuit converts a first RF signal received from the radio to a voltage signal; and
automatic gain control (AGC) circuitry coupled to the RF detector circuit, the AGC circuitry comprising:
an amplifier that i) receives the voltage 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, ii) amplifies the first portion to obtain an amplified portion of a voltage modified signal, and iii) compresses the second portion to obtain a compressed portion of the voltage modified signal;
a low-pass filter coupled to the amplifier, wherein the low-pass filter controls a rate of change of a compression gain of the AGC circuitry; and
a variable gain device coupled to the low-pass filter and the amplifier, wherein the variable gain device controls a magnitude of the compression gain of the AGC circuitry.
