Phase sensitive amplification with SIS (Superconductor-Insulator-Superconductor) quasiparticle mixers
Abstract
We have obtained the SIS junctions and RF choke structures which we will use in our experiments. These were fabricated for this project by Dr. Michael Cromar at the National Bureau of Standards Cryoelectronics Laboratory in Boulder Colorado. We have measured the dc characteristics of these junctions and have found that they have low leakage currents and RC products that are very close to our design goal. We have made preliminary calculations of the SIS mixer conversion efficiency for the real dc characteristics of our junctions and find that the results show the required phase sensitive response.
