摘要
We report the first microwave power measurement on GaN FET's, At 2 GHz, a class A output power density of 1.1 W/mm with a power added efficiency of 18.6% was obtained on al pm gate-length AlGaN/GaN MODFET, Mathematical simulation estimated that the transistor was operating at a channel temperature of 360 degrees C as a result of the poor thermal conductivity of the sapphire substrate. Despite this serious heating problem, the power output density still rivals GaAs MESFET's.
