    摘要: Systems and methods for controlling output power from a power amplifier include a power amplifier configured to generate a power output signal. An output matching circuit is in communication with the power amplifier and is configured to provide an impedance match between the power amplifier and the load. The output matching circuit includes a coupler circuit configured to detect the level of the power output signal. The coupler circuit is further configured to generate a coupler circuit output signal that is proportional to the detected output power level. A feedback control loop circuit is in communication with the coupler circuit and the power amplifier. The feedback control loop circuit is configured to control the power output level based at least in part on the coupler circuit output signal.
