This document presents a new switched-mode resonant inverter, which we term the Φ 2
inverter, that is well suited to operation at very high frequencies and to rapid on/off control …

A new family of switching amplifiers, each member having some of the features of both class
E and inverse F, is introduced. These class-E/F amplifiers have class-E features such as …

This document describes several aspects relating to the design of dc-dc converters
operating at frequencies in the VHF range (30–300 MHz). Design considerations are treated …

This paper describes a new power combining and outphasing system that provides both
high efficiency and linear output control. Whereas conventional outphasing systems utilize …

We describe a new outphasing energy recovery amplifier (OPERA) which replaces the
isolation resistor in the conventional matched combiner with a resistance-compressed …

A class-F/inverse class-F load circuit design method that includes parasitic elements such as
drain-source capacitance and bonding wire inductance has been developed. For the class-F …

To reduce the weight of a satellite, an internal wireless system (IWS) for satellites was
proposed in a previous study. It is a system that can communicate between the satellite's …

Highly efficient operation of the power amplifier can generally be obtained by applying bi-
harmonic or polyharmonic modes, when an additional single-resonant or multi-resonant …

A soft-switching inverter topology (the Class Phi) is presented which draws dc source current
through a transmission line or a lumped-network approximation of a distributed line. By …

A lossless multi-way power combining and outphasing system have recently been proposed
for high-frequency inverters and power amplifiers that offers major performance advantages …
