90 GHz Flexible Ultra-Low-Loss RF Coaxial Cable – CFD180U

Compact 90 GHz Flexible Cable for Ultra-Low-Loss Millimeter-Wave Links

The CFD180U RF coaxial cable is engineered for millimeter-wave instrumentation, with a specified operating range extending to 90 GHz. Within the CFD180U raw coaxial cable configuration, the CFD construction is aimed at extending usable bandwidth while keeping the cable flexible enough for instrument and enclosure routing. Quantitative comparison of the CFD180U coaxial cable with other Flexible Ultra-Low-Loss Coaxial Cables models should be based on the endpoint loss, power, conductor, and mechanical data below.

Bandwidth and Endpoint Attenuation

At the rated upper frequency of 90 GHz, specified attenuation is 9.072 dB/m and power handling is 0.006 kW. The transmission line incorporates a 0.40 mm silver plated copper clad steel center conductor, while the specified velocity of propagation is 76%. For the CFD180U RF cable, the 76% 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 CFD180U RF coaxial cable at the intended operating frequency.

Miniature Geometry for Crowded Enclosures

The 1.80 mm outside diameter requires a minimum static bend radius of 9.00 mm and 18.00 mm minimum dynamic bend radius, with operation specified across -55 to +125 °C. For the CFD180U raw coaxial cable, the FEP jacket must be considered in environmental, material-compatibility, and installation assessments. The compact 1.80 mm profile of the CFD180U 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 CFD180U RF coaxial cable.

Best-Fit Roles for Compact 90 GHz Links

This parameter set makes the CFD180U coaxial cable suitable for engineering evaluation in antenna feeds and compact test interconnects, subject to assembly length, connector interface, and system-level derating. For the CFD180U 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 CFD180U raw coaxial cable are required, additional construction and performance options are available in the Flexible Coaxial Cables portfolio.

Mechanc Shanghai Information Technology Co., Ltd. documents the CFD180U 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 CFD180U raw coax.
