Abstract
We have developed a set of on-chip diagnostic tools for evaluating superconducting millimeter wave circuits including: 1) a voltage-standing-wave-ratio (VSWR) reflectometer, 2) a phase meter, 3) a transmission line velocity meter, 4) a transmission line inductance meter, and 5) a double balanced mixer. The circuits consist of pure Nb conductors and Nb/AlOx/Nb SIS junctions. We report the design and use of the VSWR probe, which has not appeared in the literature, and the use of the velocity meter, the design of which has previously been reported.
