Abstract
The present status of GaN-based FETs has been described with a focus on microwave high-power performance. Our latest developments of the devices are presented, and the device and amplifier performance is reported. This includes the demonstration of a 230-W CW output power at 2 GHz, a 156-W pulsed output power at 4 GHz, and a 5.8-W CW output power at 30 GHz. The results confirmed excellent potential of the GaN-based FETs especially for high-voltage, high-power applications at microwave and millimeter-wave frequencies.
