Abstract
Apparatus and method for detecting and clamping power of a power amplifier are disclosed. In certain embodiments, a power amplifier system includes a power amplifier that amplifies a radio frequency input signal to generate a radio frequency output signal, a bias circuit that controls a bias of the power amplifier, a radio frequency coupler that generates a radio frequency coupled signal based on the radio frequency output signal, a clamp that selectively clamps the bias of the power amplifier, and a power detector that controls the clamp based on the radio frequency coupled signal.
