KEYCOM offers a variety of semi-rigid coaxial cables for cryogenic applications, shown below in Table 1,
from which you can select in view of features such 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.
*SBC: Silver plated beryllium copper (plate thickness 2.5 μm), BS:Brass, SBS: Silver plated brass (plate thickness 3.5 μm), BC: Beryllium copper, CuNi: Cupronickel, SCuNi: Silver plated cupronickel, SSUS: Silver plated SUS304
*Heat quantity required for one end of 10 cm long cable (excluding connectors) to reach 20 K or 100 K when 4 K heat anchor is applied to the other end of the cable.
