ABSTRACT:
A power amplifier includes a plurality of amplification paths in which at least one amplification path is selectively enables and disabled, wherein each amplification path includes an output impedance modification element and a phase shift element that is operable independently from the output impedance modification element, and wherein the output impedance modification element in each amplification path provides selective impedance for each amplification path.
