Abstract: Described is a phase-switched phase-switched, impedance modulation amplifier (PSIM). The PSIM has an input that can be coupled to a source and an output that can be coupled to a load. The PSIM includes one or more phase-switched reactive elements and a controller. The controller provides a control signal to each of the one or more phase-switched reactive elements. In response to one or more control signals provided thereto, each phase-switched reactive element provides a corresponding selected reactance value such that an impedance presented to an input or output port of an RF amplifier may be varied.

Abstract: A power combining and outphasing system and related techniques for simultaneously providing both wide-bandwidth linear amplification and high average efficiency is described. Providing linear amplification encompasses the ability to dynamically control an RF output power level over a wide range while still operating over a wide frequency bandwidth. The system and techniques described herein also operate to maintain high efficiency across a wide range of output power levels, such that a high average efficiency can be achieved for highly modulated output waveforms.
