Abstract :
A GaAs tunnel injection transit-time (TUNNETT) diode on a diamond heatsink yielded the state-of-the-art RF power level of more than 140 μW at 355 GHz in third-harmonic mode. The oscillator used the configuration of a WR-10 waveguide cavity for the TUNNETT diode and a WR-2 dielectric-filled conical horn with the appropriate waveguide transition for power measurements with a quasi-optical absolute power meter.
