Abstract
A power amplifier circuit comprising a scalable power amplifier including an input and an output, and a plurality of activated amplifier elements operative to produce an output signal at the output, and operative to dynamically vary a power output level of the output signal. A variable impedance circuit operatively responsive to dynamically load the output of the scalable power amplifier. Wherein the scalable power amplifier further includes an amplifier configuration circuit operatively responsive to selectively activate the selectively activated amplifier elements by at least reducing power to at least one of the selectively activated amplifier elements.
