Abstract
We design a millimeter-wave heterodyne receiver using a Superconductor Norm al metal-Superconductor (SNS) junction. We simulate its Current-Voltage Cha racteristics (CVC) as a function of its relevant physical parameters. Perfo rming computer simulations, we use the negative derivative range of its CVC to calculate the conversion gain and reflectivity coefficients of the prop osed device. These parameters show that it should be possible to increase t he sensitivity of the SNS miser and a reflection parametric amplifier may b e feasible.
