Abstract

This paper proposes the research of a single stage Broadband Solid State Power Amplifier (BPA) based on ATF13786 transistor, using GaAs process. This BPA operates in the frequency band ranging from 1.35 GHz to 3 GHz which covers the mainstream communication standards running in L and S Bands. The design approach is based on the real frequency technique. The simulated results are obtained by using ADS circuit simulator. In order to improve the broadband response, a multi-section quarter wave impedance transformer combined with an approximate transformation of a previously designed lumped elements into a transmission lines are used. The simulation results show a saturated output power of 17.85 dBm, with PAE of the 11% and a maximum power gain of 16.68 dB.
