Abstract
We have observed subharmonically pumped, switched mode mixing in superconductor-insulator-superconductor (SIS) junctions. Experiments were performed at signal frequencies of 14.4 and 16.8 GHz using PbIn-oxide-Pb junctions approximately 1 μm × ½ μm The best single sideband power conversion seen was 2.0 ± 0.5 dB gain. The lowest single sideband mixer temperature measured was 48 ± 47K. This is the first superconducting mixer to combine the advantages of subharmonic pumping with single sideband gain and low noise.
