The terahertz properties of a Double Drift Region (DDR) heterostructure IMPATT diode, based on GaN/A1GaN, are simulated for operation around 0.5 THz. The device DC to RF conversion efficiency of 17.1% and a noise measure of 21 dB, expected from the heterostructure GaN/A1GaN IMPATT diode, are noteworthy.
