Abstract :
An AlGaN/GaN heterojunction FET with a field-modulating plate has been successfully fabricated. A maximum drain current of 900 mA/mm was obtained with a gate-drain breakdown voltage of over 150 V. A 24 mm-wide FET exhibited 96 W (4.0 W/mm) output power, 54% power-added efficiency and 8.5 dB linear gain at a drain bias of 32 V.
