18 GHz Low-Temperature Superconducting Coaxial RF Cable with Nbti PTFE Construction

This offering is a low-temperature superconducting coaxial RF cable for cryogenic superconducting coaxial signal transmission. Its published construction consists of an NbTi wire inner conductor, a PTFE dielectric, and an NbTi outer conductor. The cable is specified for an operating frequency of 18 GHz with 50+/-3 ohm impedance. Its stated operating-temperature range is -269 to +200, while the table also provides attenuation values at 300 K and 4 K

The supplied information defines the cable itself and its published construction and performance parameters. It lists a 0.22 mm inner-conductor O.D., 0.65 mm dielectric O.D., and 0.86 mm outer-conductor O.D. Connector type, cable length, termination method, package contents, and assembly configuration are not specified in the table. These deliverable details should be confirmed against the requirements of an individual order

The published operating frequency is 18 GHz, and the cutoff frequency is 154 GHz. Typical attenuation at 4 K is listed below 0.5 dB/m at 500 MHz, 1 GHz, 5 GHz, 10 GHz, and 18 GHz. At 300 K, listed attenuation rises from 6.70 dB/m at 500 MHz to 48.00 dB/m at 18 GHz. Shielding efficiency is listed as 165 dB, and DC withstanding voltage is 100 V

No connector interface is identified in the supplied parameters. The coaxial structure uses an NbTi wire inner conductor, PTFE dielectric, and NbTi outer conductor, with O.D. values of 0.22 mm, 0.65 mm, and 0.86 mm respectively. The listed static bend radius is 3.20 mm, and weight is 0.0024 kg/m. The stated impedance is 50+/-3 ohm, which can be considered when evaluating a proposed system interface

An inquiry should state the required operating frequency, temperature condition, cable length, and required termination or connector interface. The published cable values include 18 GHz operating frequency, 50+/-3 ohm impedance, and an operating-temperature range of -269 to +200. For 4 K conditions, attenuation is listed below 0.5 dB/m at the published points from 500 MHz through 18 GHz.
