Abstract
We have tested a superconducting qussiparticle mixer for 85-110 GHz which gives much larger coupled gain than has been previously observed. When operated with a negative dynamic resistance of about 2000 Omega, the maximum coupled gain was G/sub M/(DSB)= 12.5 +- 0.5 dB [G/sub M/(SSB)= 9.5 +- 2.5 dB]. The associated mixer noise temperature was 15.9 K (DSB). Large gain was also observed with large positive dynamic resistance, giving the lowest mixer noise temperature of 12.4 K (DSB).
