Abstract :
A high efficient GaN HEMT power amplifier with a new topology is presented for to be used at 3.4-3.7 GHz band. Short sections of the Microstrip-lines are used as harmonic traps at the load network in order to improve the efficiency. The fabricated GaN HEMT amplifier delivers 37.5 dBm saturated output power and the maximum power-added efficiency of 80% and a maximum drain efficiency of 83% are obtained at 3.6 GHz. These values represent the state-of-the-art performance efficiencies at S-Band.
