Modern mobile communication signals require power amplifiers able to maintain very high
efficiency in a wide range of output power levels, which is a major issue for classical power …

An analytic theory for dual-input outphasing power amplifiers that incorporate in one unified
treatment, the continuum of solutions for power combining including the Doherty and Chireix …

A new type of wideband dual-input hybrid Doherty outphasing power amplifier (HDO-PA) is
developed in which the load-modulation scheme continuously converts as the frequency …

A new design methodology providing optimal mixed-mode operation for dual-input class-F
outphasing Chireix amplifiers is presented. The design starts with single-transistor class-F …

Modulation of load impedance is an effective way to maintain efficient power amplifier (PA)
operation over high dynamic range modulated signals. For high efficiency, a load …

A new design method for Doherty-Chireix combined operation is proposed. Only one of the
two amplifiers operates at the low power region like a Doherty amplifier, while both …

The demand for linear and highly efficient RF amplifiers has continued to rise without
showing signs of stopping, as the world looks to the implementation of 5G. Modern …

This paper presents the analysis, design and measured performance of a harmonically-
tuned dual-input Doherty-outphasing power amplifier (DOPA) that can maintain high …

This paper presents a GaN HEMT outphasing power amplifier (PA), based on a class-E/F 2
topology with reduced sensitivity to variable resistive load operation, designed to provide …

This paper presents a two-way hybrid Doherty-outphasing power amplifier (HD-OPA) with
an optimal efficiency. The HD-OPA consists of a main PA operating in class-F and an …
