Semi-Rigid Cables for Cryogenic (Super Low Temperature) Applications
upj02002001108-07
KEYCOM offers wide variety of superconducting semi-rigid coaxial cables for cryogenic applications, 
shown below in Table 1, from which you can select based on such features as heat conductivity, 
flexibility, insertion loss, permeability, or thickness to meet your specific requirements.
They are low in heat conductivity, minimizing inflow of the heat from the high-temperature end.  
Operating frequency is DC-40GHz by default, but available up to 65GHz upon request.
The characteristic impedance is 50Ω.
