ABSTRACT:
The output power of an RF power amplifier is controlled using a feedback loop including a differential integrator for controlling the amplifier's bias voltage. The gain of integration in the differential integrator is varied so as to compensate for variations in the derivative of the power amplifier output power versus the bias voltage.
