A 112W GaN dual input Doherty-Outphasing Power Amplifier

Conference paper - A.R. Qureshi, M Acar, J.H. Batool, R Wesson, L.C.N. de Vreede

This paper presents a novel dual-input Doherty-Outphasing Power Amplifier (DOPA) architecture that combines the efficiency advantages of Doherty and Outphasing amplifiers in power back-off (PBO). The proposed architecture, utilizes Doherty operation from peak power to -6dB PBO an ...
