The Analytic Doherty-Outphasing Power Amplifiers Continuum Theory : (Invited Paper)

This paper reviews a narrow and wide band high-efficiency dual-input power amplifiers (PA) design approach based on the previously reported Doherty-Outphasing PA continuum theory. The key derived analytic equations are summarized to explain the theory. Several GaN PA demonstrator circuits are presented and experimentally evaluated. The promising performance achieved validates the usefulness of the DohertyOutphasing PA continuum theory.
