Abstract
L- and S-band high power GaAs FETs have been developed. At 1.8 GHz, the FET delivers an output power at 1 dB gain-compression point of 42.7 W (46.3 dBm) with 13.3 dB gain and 42% power-added efficiency, and a saturated output power of 51.3 W (47.1 dBm). The developed FETs will contribute to improve the performance of microwave SSPAs used in various radar and communication systems which require higher output power and low distortion.
