ABSTRACT:
Power amplifier with switchable load. A first amplifier that includes an output electrode is provided. A second amplifier that includes an output electrode is also provided. A switchable load that receives a control signal selectively presents a first impedance to the first amplifier when the first amplifier is operational, and the second amplifier is not utilized, and presents a second impedance to the second amplifier when the second amplifier is operational, and the first amplifier is not utilized based on the control signal.
