18 GHz Semi-Rigid Cryogenic RF Coaxial Cable – CRT086

Low-Temperature 18 GHz Semi-Rigid Cable for Cryostat RF Connections

For frequency-critical superconducting experiments, the CRT086 RF coaxial cable delivers a documented operating ceiling of 18 GHz. Within the CRT086 raw coaxial cable configuration, the CRT conductor system is specified down to -268 °C for signal routing into cryogenic stages where ordinary cable materials are unsuitable. Quantitative comparison of the CRT086 coaxial cable with other Cryogenic Semi-Rigid Coaxial Cables models should be based on the endpoint loss, power, conductor, and mechanical data below.

RF Feedthrough Paths Inside Cryostats

These characteristics support the use of the CRT086 coaxial cable in cryostats and quantum research platforms, provided the final assembly design respects the stated bend and power limits. For the CRT086 coaxial cable, this documented specification set enables disciplined comparison against alternative cable diameters and performance classes. When alternatives to the CRT086 raw coaxial cable are required, additional construction and performance options are available in the Semi-Rigid Coaxial Cables portfolio.

RF Performance for Cryostat Interconnects

The band-edge specification at 18 GHz defines 4.960 dB/m attenuation together with 0.024 kW power capacity. The conductor system uses silver plated copper-nickel alloy at 0.56 mm diameter and provides a specified velocity of propagation of 77%. For the CRT086 RF cable, the 77% propagation value provides the basis for estimating electrical delay and timing skew over the required assembly length. Together, these values support link-loss, electrical-delay, and power-margin calculations for the CRT086 RF coaxial cable at the intended operating frequency.

Cryostat Routing with a Defined Cable Envelope

Mechanical integration is governed by a 2.15 mm cable diameter, a 4.30 mm minimum static bend radius, and a temperature range of -268 to +150 °C. During installation of the CRT086 raw coaxial cable, routing should remain within the specified bend geometry throughout forming, connectorization, and installation. The compact 2.15 mm profile of the CRT086 RF cable facilitates constrained routing without relaxing the specified bend limits. Compliance with these constraints helps protect impedance continuity and repeatability at the cable-to-connector transition associated with the CRT086 RF coaxial cable.

Mechanc Shanghai Information Technology Co., Ltd. documents the CRT086 RF coaxial cable with product-specific parameters so that RF engineers can evaluate the interconnect against system bandwidth, loss budget, power, thermal, and packaging requirements. Within the product portfolio, this configuration is designated as the CRT086 raw coax.
