Compact subharmonic mixer for EHF wave receiver using a single wave guide and receiver utilizing such a mixer

摘要

A subharmonic mixer, whose local oscillator is at half the frequency of that of the signal to be received, comprising a detector and a local oscillator positioned in a single waveguide (301). The mixer comprises a first module (51) serving as the local oscillator and incorporating an oscillation diode surrounded by dielectric material and connected to a wide metal coating, as well as a second module (52) incorporating an antiparallel connection of two Schottky diodes and which is identical to the first module. The metal coatings of these two modules are in contact with metallized areas (53, 54) of a double-faced printed circuit (15) serving for the polarization of one module and for the signal output of the other.
