This paper proposes a high-efficiency microwave power amplifier operating at X-band using an adaptive bias method for AESA radar application. The designed power amplifier delivers 5 W at 9.5 GHz with more than 40% of PAE and 10 dB Gain. The designed power amplifier was designed in a Keysight ADS software. To meet requirements of the AESA radar system, an adaptive bias technique is employed to prevent degradation of the PA performance with respect to the variation of the input power. The simulated results show that by making a proper adjustment of drain bias voltage from 22 V to 32 V, performance of the PA can be remained regardless of input power change from 22 dBm to 30 dBm. |
