Abstract
In the paper, 30 mm high-power SiC MESFETs have been fabricated. By load-pull testing at 1.5 GHz and 48 V drain to source voltage, packaged 2×30 mm SiC MESFET transistors were demonstrated with output power higher than 107 W with 48.1% PAE, and the gain was 10.3 dB under continuous wave RF operation. Small gate periphery devices of 1 mm SiC MESFET exhibited 35 dBm output power with more than 55% PAE, and the gain was 12.3 dB under continuous wave RF operation at 1.5 GHz and 48 V drain to source voltage.
