  • Abstract
    The electrical performance of high current density AlGaN/GaN HEMTs is reported. 2 × 75 μm × 0.7 μm devices grown on sapphire substrates showed current densities up to 2.1 A/mm under 200 ns pulse condition. RF power measurements at 8 GHz and VDS=15 V exhibited a saturated output power of 3.66 W/mm with a 47.8% peak PAE.
