Characterization of a Frequency Converter Based on a Superconducting Coplanar Waveguide, IMS 2024

We plan to present a technique for implementing a frequency doubler in NbTiN on silicon for operation in a cryogenic environment at IMS 2024. The kinetic inductance of a superconducting coplanar waveguide is exploited for efficient frequency conversion, while the fabrication allows for co-location with other cryogenic circuits. A conversion efficiency greater than 10% is demonstrated at a frequency of 9.87 GHz, offering lower input power requirements and competitive conversion efficiencies relative to other state-of-the-art solutions. This dataset contains information related to this presentation, specifically: (Fig. 2) Simulated conversion efficiency result, (Fig. 4) 2nd and 3rd order harmonic conversion efficiency data with input RF power ranging from (3 to 7), and (Fig. 5) second harmonic power as a function of dc bias current.
