18 GHz Cryogenic Superconducting Coaxial RF Cable with PTFE Dielectric

This offering is a cryogenic superconducting coaxial RF cable for coaxial signal transmission. Its specified construction includes a silver-plated CuNi inner conductor, PTFE dielectric, and CuNi outer conductor. The cable has a listed operating frequency of 18 GHz and a characteristic impedance of 50+/-2.5 ohm. The available information does not identify a specific end-use application, connector termination, cable assembly service, or accessory

The listing covers one defined coaxial cable configuration with a 0.30 mm silver-plated CuNi inner conductor, 0.95 mm PTFE dielectric, and 1.20 mm CuNi outer conductor. Its listed weight is 0.0062 Kg/m, and the specified static bend radius is 4.20 mm. No supplied cable length, packaging quantity, connector termination, or additional deliverable is stated. These commercial details should be confirmed when preparing an order inquiry

The cable is specified for operation at 18 GHz, with a listed cutoff frequency of 117 GHz. Its velocity is 70%, shielding efficiency is 165 dB, and withstanding voltage is 100 V DC. Typical attenuation is provided at both 300 K and 4 K from 500 MHz through 18000 MHz. At 18000 MHz, the listed values are 10.80 dB/m at 300 K and 4.40 dB/m at 4 K; at 5000 MHz, they are 5.70 dB/m and 2.30 dB/m respectively

The cable has a coaxial structure comprising a silver-plated CuNi inner conductor, PTFE dielectric, and CuNi outer conductor. The respective conductor and dielectric diameters are 0.30 mm, 0.95 mm, and 1.20 mm for the outer conductor. Its operating-temperature range is listed as -268 to +150, and its static bend radius is 4.20 mm. No connector type, mating interface, or equipment compatibility statement is provided in the available product data

Before inquiry, confirm the required operating frequency, impedance requirement, cable length, and connector termination, since length and connectors are not specified. The listed impedance is 50+/-2.5 ohm, while attenuation is stated separately at 300 K and 4 K. At 18 GHz, typical attenuation is 10.80 dB/m at 300 K and 4.40 dB/m at 4 K.
