Summary

The authors have fabricated a miniature coaxial transmission line with characteristics suitable for cryogenic applications. The materials were chosen for reduced thermal conduction and improved high-frequency signal transmission, and for mechanical properties allowing easy connector assembly and forming into complicated cryogenic structures. Defining the figure of merit as a product of the signal attenuation per unit lenght and the heat conduction integral, the line is superior to all commercial cryogenic lines above 80 K, and allows much easier soldering and bending. Further improvements of the line are also briefly discussed.
