Abstract
In this paper, the efficiency of power amplifier has been maximized by the application of EER structure, and the linearity has been improved by using PBG structure. This paper has proposed a design of power amplifier in class-F to get the PAE, and to control dynamic power using envelope detector. PBG structure gets high-linearity by removing harmonics arisen from the mismatching of matching circuit. The PAE and the 3rd order IMD have been improved 34.64%, 6.65 dB compared with those of conventional Doherty amplifier, respectively.
