Abstract:A comparison between a fully integrated Doherty power amplifier (DPA) and outphasing power amplifier (OPA) for fifth Generation (5G) wireless communications is presented in this paper. Both amplifiers are integrated using pHEMT transistors from the OMMIC’s 100 nm GaN-on-Si technology (D01GH). After a theoretical analysis, the design and layout of both circuits are presented. The DPA uses an asymmetric configuration where the main amplifier is biased in class AB and the auxiliary amplifier is biased in class C,… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
