Cryogenic On-chip In Situ S-parameter Calibration Using Superconducting Coplanar Waveguides

These data will appear in [1]. The abstract for that paper is given below:This paper presents an in situ S-parameter calibration technique using on-chip superconducting transmission lines at 4 K. The method uses coplanar waveguide (CPW) models based on various impedance states of niobium (Nb), which has zero dc resistance below 9 K and a monotonically increasing resistance from 10 K to room temperature. These impedance states are accessed by heating the 4 K stage of a cryostat and injecting up to 185 mA of current into the line and are used to solve for the unknowns in an 8-term error model using a least-squares analysis. We demonstrate this calibration method using Nb CPWs with and without embedded Josephson junctions (JJs), achieving S-parameter calibrations with self-consistency better than 0.1 dB from dc to 3 GHz.[1] Thomas, J.
