Flexible Coaxial Ribbon Cable for High-Density Superconducting Microwave Device Arrays
Flexible Coaxial Ribbon Cable for High-Density Superconducting Microwave Device Arrays
Superconducting electronics often require high-density microwave interconnects capable of transporting signals between temperature stages with minimal loss, cross talk, and heat conduction. We report the design and fabrication of superconducting 53 wt% Nb-47 wt% Ti (Nb47Ti) FLexible coAXial ribbon cables (FLAX). The ten traces each consist of a 0.076 mm …
