Abstract :
585 GHz diffusion-cooled Nb HEB (d-HEB) mixers utilizing slot-ring antennas have been designed and fabricated on silicon wafers. To optimize power coupling from the antennas to the mixing elements, two impedance matching schemes are proposed. Performance at 585 GHz of the mixers including I-V curves, conversion gain and noise temperature are presented.
