This article introduces a novel high-order load modulation power amplifier (PA) architecture,
ie, continuous-mode hybrid asymmetric load modulated balanced amplifier (H-ALMBA). The …

In this paper, a novel modified Doherty power amplifier (DPA) that allows for extended
output back-off (OBO) range, improved power utilization factor (PUF), and increased peak …

An improved reconfigurable Doherty power amplifier (DPA) structure with extended
bandwidth is presented. A traditional DPA structure is often used to expand the output power …

This article presents a generalized theory and new design methodology for reverse-load-
modulated dual-branch (RMDB) power amplifiers (PAs), which uses a current-biased …

In this article, based on a dual-input configuration (DIC), a method for implementing
ultrawideband or multiband load-modulated Doherty power amplifiers (DPAs) is proposed …

This paper proposes a new methodology for designing wideband Class J Doherty power
amplifiers (DPAs). The paper begins by presenting a network analysis that leads to a set of …

Modern wireless communication systems with large bandwidth and high peak-to-average
power ratios (PAPRs) have been and will continue to be in high demand. This puts a strain …

Previously, the bandwidth of conventional Doherty power amplifiers (DPAs) is limited by the
phase dispersion of the microstrip impedance transformer (IT). To overcome this phase …

This paper presents a novel general design method of frequency varying impedance
matching. The method is applied to design of a broadband high-efficiency power amplifier …

In this paper, a continuous mode Doherty power amplifier (DPA) working over an octave
bandwidth is constructed using a generalized combiner. The generalized combiner provides …
