Abstract

RF coupling to Superconductor-Isolator-Superconductor (SIS) junctions suffers from their large geometric capacitance (45 to 60 fF/μm² for Nb-Al₂O₃-Nb junctions). Junction areas smaller than 1 μm² would be necessary for submillimeter wavelengths but pose considerable difficulties in fabrication. We show mixer performance calculations for moderately sized junctions using an integrated open circuited microstrip stub to tune out the junction capacitance.
