18 GHz 086 Stainless Steel Cryogenic RF Coaxial Cable G22E-SS
P/N: G22E-SS
- For larger low-thermal-load RF paths
- Stainless steel conductors reduce heat conduction
- 2.17 mm OD supports stable cable routing
- Suited to quantum input and control lines
- Rated to 18 GHz for cable selection
Engineering Note
The G22E-SS is a 2.17 mm OD stainless steel cryogenic RF coaxial cable designed for larger-format low-thermal-load routing where reduced heat conduction into cold stages is a key design requirement. Its construction uses a stainless steel inner conductor, PTFE dielectric, and stainless steel outer conductor, supporting dilution refrigerator interconnects, cryogenic RF routing between temperature stages, and larger quantum system input or control paths. The 18 GHz operating frequency is intended for preliminary cable selection; final assembly performance may depend on connector interface, cable length, routing form, thermal anchoring, and operating temperature stages.
