Abstract

See full text

Technologies directed to a control circuit using dynamic signal compression are described. A control circuit includes a front-end module (FEM) coupled to an RF cable, the FEM having a low-noise amplifier (LNA). The control circuit further includes an automatic gain control (AGC) circuitry coupled to the FEM. The AGC circuitry receives a first radio frequency (RF) signal having a first portion of one or more symbols and a second portion of one or more symbols. The AGC circuitry further amplifies the first portion to generate a first portion of an output signal. The AGC circuitry further compresses the second portion to obtain a second portion of the output signal. The AGC circuitry further 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.
