A Fixed-Tuned 400 GHz Subharmonic Mixer Using Planar Schottky Diodes

Jeffrey L. Hesler, Kai Hui, Song He, Thomas W. Crowe
Abstract:
The design and testing of a 400 GHz fixed-tuned subharmonic mixer using antiparallel planar Schottky bather diodes is presented. Fixed-tuned, two-sided waveguide-to- microstrip transitions are used to couple power into a microstrip channel, in which the diode is mounted. A low-pass filter is used to block the RF signal, and a short-circuited half-wave stub is used to terminate the LO. The first tests of the mixer yielded a double-sideband mixer noise temperature of 1120 K and a mixer conversion loss of 8.0 dB at 420 GHz using 5 mW of local oscillator power.
