On-Chip Frequency Conversion Using Kinetic Inductance Within a Coplanar Waveguide, IEEE Transactions on Applied Superconductivity 2024

Dataset for publishable figures in a "On-Chip Frequency Conversion Using Kinetic Inductance Within a Coplanar Waveguide" manuscript to be submitted to IEEE Transactions on Applied Superconductivity. This work presents a method of frequency conversion which exploits the kinetic inductance of a superconducting coplanar waveguide. Both frequency doubling and tripling are examined, with attention paid to conversion efficiency. This approach allows up-conversion to be implemented in a cryogenic environment, which can simplify the design of cryogenic systems. We achieved a conversion efficiency of 12.7% when up-converting a 10 GHz fundamental tone to the 20 GHz second harmonic, which is an improvement compared to higher-power room-temperature commercial offerings. To better understand device behavior, we also develop a measurement-based model using a harmonic balance simulation, and achieved good agreement between measurements and simulations.
