Abstract :
This contribution describes the design and validation of a L-band hybrid high power amplifier for radar application with high power added efficiency (PAE). The HPA is designed using a commercial GaN device by Cree, in a single ended configuration, starting from a simulated load-pull approach. Pulsed measurements of the designed PA demonstrate 90 W of saturated output power across the desired bandwidth with an average PAE of 50%.
