Abstract : Josephson junctions are used in the patent to accomplish frequency conversion--either down conversion or up conversion. The junction is coupled to a resonant cavity and simultaneously irradiated by an external source at frequency f, which differs from the resonant frequency of the cavity f sub c. In order for an output to be produced at this frequency, f sub c, the voltage bias across the junction must be at one of the values V = h(the absolute value of (f sub c plus or minus nf))2e, where n is an integer and the absolute value is used since nf may be larger than f sub c.
