Some Recent Developments in the Design of SIS Mixers

Authors:
A.R. Kerr, S.-K. Pan
Abstract:
This paper describes SIS mixers in use or under development at NRAO, and introduces a new design procedure for SIS mixers. By using broadband waveguide-to-stripline transducers, it is possible to design SIS mixers which do not require reduced height waveguide. At the shorter millimeter wavelengths this greatly simplifies mixer fabrication and allows the use of non contacting waveguide tuners. The use of superconducting circuit elements integrated with the junction (or array of junctions) to tune out the usually large junction capacitance has made possible a tunerless mixer which covers a full waveguide band.
