Abstract: A power control circuit is coupled to receive a feedback signal from a power amplifier (PA) and generate a control signal to control a variable gain amplifier (VGA) coupled to an input to the PA based on the feedback signal. The power control circuit may include, in one embodiment, a mute circuit to generate a mute signal to be provided to the VGA when the control signal is less than a first level and a clamp circuit to clamp a control voltage used to generate the control signal from exceeding a threshold level.
