Abstract
A single-stage power amplifier(PA) operating in the 3.4~3.6GHz is designed in this paper, which is mainly used as a driver-stage PA for wireless transmitter. In the design process, the advanced designed system(ADS) of Agilent company is adopted, and the transistor of the PA is selected from Cree’s GaN transistor model CGH40010F. The simulation results show that the saturated output power exceeds 41 dBm, the PAE is greater than 65%, and the gain is around 17 dB when the output power is lower than 40dBm. The test results show that maximum PAE and output power are 55% and 40dBm, respectively. Compared with the traditional narrow band PA, the designed PA in the paper achieves relatively well bandwidth and efficiency.
