This randomized trial demonstrates enhanced performance of a power amplifier MMIC for electronics warfare applications, suggesting promising advancements.
The design and performance of a wideband power amplifier MMIC suitable for electronic warfare (EW) systems and other wide bandwidth applications is presented. The amplifier utilizes dual field plate 0.25-mum GaN on SiC device technology integrated into the three metal interconnect (3MI) process flow. Experimental results for the MMIC at 30V power supply operation demonstrate greater than 10 dB of small signal gain, 9 W to 15 W saturated output power and 20% to 38% peak power added efficiency over a 1.5 GHz to 17 GHz bandwidth.
