A Segmented Internally-Matched Class J GaN Power Amplifier for High Duty Cycle C-Band Radars

An internally matched 70 W class J GaN power amplifier for C-band radar remote sensing applications is demonstrated. The amplifier achieves 50% power added efficiency at 7900 ± 10 MHz, using a pulsed waveform with 30% duty cycle. The amplifier features a segmented matching network inside a metal flange package to synthesize a reactance at the fundamental and operates in class J mode
