18 GHz Cryogenic RF Coaxial Cable with Stainless Steel PTFE Construction

This offering is a low-temperature RF coaxial cable for signal transmission. Its documented construction uses a stainless-steel inner conductor, PTFE dielectric, and stainless-steel outer conductor. The listed operating-temperature range is -268 to +150, and typical attenuation values are provided at both 300 K and 4 K. No specific end-use equipment, installed application, or integration service is stated in the supplied product parameters

The available information identifies one cable configuration with a 0.29 mm stainless-steel inner-conductor O.D., 0.95 mm PTFE dielectric O.D., and 1.22 mm stainless-steel outer-conductor O.D. It further lists a 4.20 mm static bend radius and a weight of 0.004 kg/m. Connector type, cable length, termination, packaging contents, and accessories are not specified. Buyers should confirm required deliverables and termination details when submitting an inquiry

The cable is specified for 18 GHz operation, with a listed cutoff frequency of 110 GHz and impedance of 50+/-2.5 ohm. Other listed electrical parameters are 70% velocity, 165 dB shielding efficiency, and 100 V DC withstanding voltage. Typical attenuation is provided from 500 MHz through 18000 MHz at both 300 K and 4 K. At every listed frequency, the stated attenuation at 4 K is lower than the corresponding value at 300 K

No connector type, mating interface, or equipment compatibility is specified for this RF cable. Its coaxial structure comprises stainless-steel inner and outer conductors separated by a PTFE dielectric, and the outer-conductor O.D. is listed as 1.22 mm. The specified static bend radius is 4.20 mm, while the operating-temperature range is -268 to +150. Buyers should verify termination, mating, routing, and installation compatibility with their own equipment requirements

For an inquiry, provide the required operating frequency, impedance requirement, temperature condition, and cable length. This configuration is listed for 18 GHz operation with 50+/-2.5 ohm impedance, and attenuation data is available at 500, 1000, 5000, 10000, and 18000 MHz under 300 K and 4 K conditions. Buyers should also check whether the 1.22 mm outer-conductor O.D. and 4.20 mm static bend radius suit the installation.
