This paper presents an analysis of using GaN supply-modulated (SM) power amplifier (PA) in an active electronically scanned array (AESA) system to improve system power efficiency. Specifically, the paper details a 4-W X-band GaN SM PA with power-added efficiency (PAE) of above 50% at 9.4 GHz frequency. The proposed PA achieves the PAE of above 35% over 800 MHz bandwidth and 40% in 10 dB output power back-off range. The simulation results show that the system PAE increases about 14–18% at the same condition of the array amplitude distribution and array scales by using GaN SM PA. © 2021, ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering.
