Journal ArticleDOI
Broad-Band RF Match to a Millimeter-Wave SIS Quasi-Particle Mixer
TL;DR: In this paper, an integrated superconducting microstrip is shown to be a convenient, flexible, and well-characterized matching element for a super-conductor-insulator- superconductor (S1S) quasi-particle heterodyne mixer.
Journal ArticleDOI
Accurate noise measurements of superconducting quasiparticle array mixers
TL;DR: In this article, the authors constructed a 30-40 GHz test apparatus which allows them to measure the noise temperatures of SIS mixers with an accuracy of better than ±1K.
Journal ArticleDOI
MM wave quasioptical SIS mixers
TL;DR: In this article, the performance of planar SIS mixers with log-periodic antennas at near millimeter and submillimeter wave frequencies from 90 to 360 GHz was evaluated.
Journal ArticleDOI
Measurement of integrated tuning elements for SIS mixes with a Fourier transform spectrometer
TL;DR: In this article, a Fourier transform spectrometer with an Hg-arc lamp source was used as an RF sweeper to measure the frequency response of a planar lithographed quasioptical mixers.
Journal ArticleDOI
Wide-band low noise MM-wave SIS mixers with a single tuning element
TL;DR: In this article, the SIS quasiparticle mixers have been designed and tested for the frequency range from 80 to 115 GHz and the sliding backshort is the only adjustable RF tuning element.
