18 GHz Semi-Rigid Cryogenic RF Coaxial Cable – CRT034

Cryogenic 18 GHz Semi-Rigid Cable for Compact Low-Temperature Systems

The CRT034 RF coaxial cable is a purpose-engineered cable for low-temperature detectors, specified for RF transmission through 18 GHz. Within the CRT034 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 CRT034 coaxial cable with other Cryogenic Semi-Rigid Coaxial Cables models should be based on the endpoint loss, power, conductor, and mechanical data below.

Electrical Planning for Ultra-Cold Stages

At the rated upper frequency of 18 GHz, specified attenuation is 13.851 dB/m and power handling is 0.023 kW. A 0.21 mm silver plated copper-nickel alloy inner conductor establishes the conductive path, with a documented propagation velocity of 77%. For the CRT034 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 CRT034 RF coaxial cable at the intended operating frequency.

Compact Cryogenic Instruments and Research Platforms

This parameter set makes the CRT034 coaxial cable suitable for engineering evaluation in superconducting experiments and cryostats, subject to assembly length, connector interface, and system-level derating. For the CRT034 coaxial cable, the result is a product-specific RF interconnect option supported by the electrical and mechanical data required for design review. When alternatives to the CRT034 raw coaxial cable are required, additional construction and performance options are available in the Semi-Rigid Coaxial Cables portfolio.

Compact Semi-Rigid Layout for Cold Instruments

The 0.86 mm outside diameter requires a minimum static bend radius of 4.30 mm, with operation specified across -268 to +150 °C. During installation of the CRT034 raw coaxial cable, routing should remain within the specified bend geometry throughout forming, connectorization, and installation. The subminiature 0.86 mm profile of the CRT034 RF cable supports dense RF packaging, while requiring controlled forming and termination practices. Compliance with these constraints helps protect impedance continuity and repeatability at the cable-to-connector transition associated with the CRT034 RF coaxial cable.

Mechanc Shanghai Information Technology Co., Ltd. documents the CRT034 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 CRT034 raw coax.
