Abstract

Radio frequency (RF) front ends with integrated channel matching calibration are provided herein. In one aspect, a front end system includes: a plurality of front end amplification chains including transmit and receive chains for at least two radio frequency bands, each of the front end amplification chains configured to either transmit or receive radio frequency signals via one of a plurality of antennas, and each of the front end amplification chains includes an amplifier configured to receive a bias current and amplify the corresponding radio frequency signal based on the bias current, a control circuit configured to generate each of the bias currents, and a multiplexor configured to receive the bias currents and provide the bias currents to the corresponding amplifiers.
