Patent abstract
System for linear amplitude modulation. Apparatus is provided for linear amplitude modulation of an amplifier. The apparatus includes a processing circuit that receives an amplitude modulation signal and produces one or more amplifier control signals that are coupled to the amplifier. The apparatus also includes a feedback circuit that generates a feedback signal from an output of the amplifier that is input to the processing circuit; and a network that controls a bias of the amplifier in response to the feedback signal to linearize the amplifier's amplitude control.
