  • Abstract
    In this paper, we report measured fmax data of over 300 GHz on an MOCVD-grown N-polar GaN HEMT using a high-aspect-ratio T-gate. To our knowledge, this >; 300-GHz fmax value is the highest reported to date for N-polar GaN HEMTs and is 50% higher than the previously reported value (Nidhi et al., 2010).
