Power amplifier amplitude modulator system and method

A power amplifier with power control comprising:

• a detector for detecting one or more of a voltage envelope and a current envelope;
• a controller for controlling an attenuation of one or more of the voltage envelope and the current envelope;
• means for generating a control signal based on the greater of the voltage envelope and the current envelope;
• and
• a variable gain amplifier coupled to the detector and a power amplifier level controller, the variable gain amplifier increasing a gain of a control signal generated by the detector when the controller decreases an attenuation for one or more of the voltage envelope or the current envelope.

A method for generating a power amplifier control signal comprising:

• attenuating one or more of a voltage envelope signal or a current envelope signal based on power level data;
• generating a power amplifier control signal based on a detector control signal and a greater of the attenuated voltage envelope signal or the attenuated current envelope signal;
• and
• increasing a gain of the detector control signal using a variable gain amplifier when attenuation control data decreases an attenuation for one or more of the voltage envelope signal or the current envelope signal.
