RFIC with dynamically controlled power amplifier

摘要

A radio frequency (RF) front-end includes a power amplifier module and a power amplifier control module. The power amplifier module is coupled to amplify an outbound RF signal in accordance with a control signal to produce an amplified outbound RF signal. The power amplifier control module is coupled to generate the control signal based on at least one of forward power of the amplified outbound RF signal and reflected power of the amplified outbound RF signal.
