- Abstract
- The Doherty power amplifier (DPA) with cascaded peaking cells is reported The auxiliary peaking cell at the input of the main peaking cell is employed to enhance the efficiency and linearity of DPA For the experimental validation the main DPA and an auxiliary peaking cell ale designed using St LDMOSFETs and a GaN HEMT respectively From the measured results the power added efficiency is increased at a 6 a back off power and the adjacent channel leakage ratio is enhanced over a whole output power range (C) 2010 Wiley Periodicals Inc Microwave Opt Technol Lett 53 208-211 2011 View this article online at wileyonlinelibrary com DOI 10.1002/mop.25682
