This paper reports on calculations based upon which the quantum theory of mixing in single-particle tunnel junctions which show that there is a fairly simple strategy for optimizing the performance of double-sideband SIS quasiparticle mixers. The best mixer noise temperature is obtained when the signal source is matched to the LO admittance of the junction. This applies over a very wide range of LO and DC bias conditions.
