We report on the electrical performances of high current density AlGaN/GaN HEMTs. 2x75μmx0:7μm devices grown on sapphire substrate showed current densities up to 2.1A/mm under 200ns pulse condition. RF power measurements at 8GHz and VDS = 15V exhibited a saturated output power of 3.66W/mm with a 47.8% peak PAE

Abstract
We report on the electrical performances of high current density AlGaN/GaN HEMTs. 2x75μmx0:7μm devices grown on sapphire substrate showed current densities up to 2.1A/mm under 200ns pulse condition. RF power measurements at 8GHz and VDS = 15V exhibited a saturated output power of 3.66W/mm with a 47.8% peak PAE
