We realized GaN based Field Effect Transistors to be used both for direct and heterodyne detection of mm wave / THz signals. Polarization-sensitive, planar antennas were designed and integrated on chip. Device were fabricated relying on an industrial III-V platform. Spectral response in the 0.22-0.38 THz range was acquired. An efficient mixing between gate voltage and drain current was shown.

Abstract
We realized GaN based Field Effect Transistors to be used both for direct and heterodyne detection of mm wave / THz signals. Polarization-sensitive, planar antennas were designed and integrated on chip. Device were fabricated relying on an industrial III-V platform. Spectral response in the 0.22-0.38 THz range was acquired. An efficient mixing between gate voltage and drain current was shown.File in questo prodotto:
