This paper will focus on developing an exotic switching technique that enhances the DC-to-RF conversion efficiency of microwave power amplifiers. For years, switching techniques implemented in the 10-kHz to 30-MHz region have resulted in DC-to-RF conversion efficiencies of 90–95-percent. Currently amplifier conversion efficiency, in the 2–3 GHz region approaches, 10–20-percent. Using a combination of analytical modeling and hardware testing, a High Efficiency Microwave Power Amplifier was built that demonstrated conversion efficiencies four to five times higher than current state of the art.
