1. Design and Implementation of as Asymmetric Doherty Power Amplifier at 2.65 GHz in GaN HEMT Technology
University essay from Elektroniska komponenter; Tekniska högskolanAbstract : Power amplifiers are an indispensible part of the wireless communication systems. Conventional PAs provide peak efficiency at peak output power which is obtained at a certain fixed optimum resistance. These kind of amplifiers are normally called switched-mode power amplifiers (SMPAs) and are used for constant envelope signals. READ MORE
