In this letter, the power range to be covered with maximized efficiency by a two-way outphasing power amplifier (PA) is significantly extended thanks to a proposed architecture with injection of an external signal. Using a reactively terminated quadr

This paper presents a simple switch model for a GaN HEMT device, extracted to estimate the output power and efficiency load-pull contours when the transistor is used in a UHF class-E power amplifier (PA). The impact of model parameters on the theoret

This paper reviews the use of UHF double class-E (class-E2) topologies for dc/dc power conversion. After introducing this attractive resonant converter in the context of the time-reversal duality principle, two different lumped-element networks are d
