Abstract
An amplifier circuit includes a power amplifier configured to amplify an RF input signal to obtain an RF output signal, and a bias controller configured to control a bias of the power amplifier. The bias controller is configured to determine a measure of a load impedance of a load coupled to an output of the power amplifier and provide a bias control signal to adjust the bias of the power amplifier based on the determination of the measure of the load impedance.
