Abstract :
This paper presents a 2.469~2.69 GHz AlGaN/GaN HEMT power amplifier for IEEE 802.16e WiMAX applications operating at E mode under a single supply of +6v. At the central frequency point, the power added efficiency (PAE) can achieve 96.37%, the small signal gain is 20.81dB, and the output power is 25.39dBm. The paper describes the circuit design in detail, then shows the simulation results and discusses about the simulation results. In the end, the paper concludes the design.
