In this paper, we experimentally investigate the effects of degradation observed on 0.15-µm GaN HEMT devices when operating under realistic power amplifier conditions. The latter will be applied to the devices under test (DUT) by exploiting a low-fr

This paper presents a novel and accurate procedure for designing a Doherty power amplifier (DPA) for wireless systems. The method is based on a systematic approach to designing the matching networks of both Main and Auxiliary devices, which employs a

This paper proposes a design method to minimize the phase distortion (AM/PM) in gallium nitride (GaN) power amplifiers (PAs) without significantly worsening other key features such as efficiency, amplitude distortion, and gain. The design strategy co

Available techniques for stability analysis of DC solutions, such as the popular Ohtomo test, make the task quite a straightforward one. Such tests are based on the assumption that the active subcircuit is inherently stable, which is reasonably easy

This paper presents the theoretical analysis of phase distortion (AM/PM) mechanisms in Gallium Nitride (GaN) Doherty power amplifiers (DPAs) and a novel approach to optimize the tradeoff between linearity and efficiency. In particular, it is demonstr
