Abstract
Systems and methods are provided for power amplifiers with discrete power control. The systems and methods may include a plurality of unit power amplifiers; a plurality of primary windings, wherein each primary winding is connected to at least one respective output port of a respective one the plurality of unit power amplifiers; a secondary winding inductively coupled to the plurality of primary windings, where the secondary winding provides an overall output; a bias controller, where the bias controller provides a respective bias voltage based at least in part on a level of output power to one or more of the plurality of unit power amplifiers; and a switch controller, where the switch controller operates to activate or deactivate at least one of the plurality of unit power amplifiers via a respective control signal.
