Abstract

Aluminum nitride (AlN) offers novel potential for electronic integration and performance benefits for high-power, millimeter-wave amplification. Herein, load-pull power performance at 30 and 94 GHz for AlN/GaN/AlN high-electron-mobility transistors (HEMTs) on silicon carbide (SiC) is reported. When tuned for peak power-added efficiency (PAE), the reported AlN/GaN/AlN HEMT shows PAE of 25% and 15%, with associated output power ( P out ) of 2.5 and 1.7 W mm−1, at 30 and 94 GHz, respectively. At 94 GHz, the maximum P out generated is 2.2 W mm−1, with associated PAE of 13%.
