67 GHz Flexible Ultra-Low-Loss RF Coaxial Cable – CFD230U

Wideband 67 GHz Flexible Cable for Low-Loss RF Signal Routing

For antenna feeds, the CFD230U RF coaxial cable provides a technically defined transmission-line solution rated through 67 GHz. Within the CFD230U 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 CFD230U coaxial cable with other Flexible Ultra-Low-Loss Coaxial Cables models should be based on the endpoint loss, power, conductor, and mechanical data below.

Routing a Compact Flexible Profile

Mechanical integration is governed by a 2.20 mm cable diameter, a 15.00 mm minimum static bend radius and 22.00 mm minimum dynamic bend radius, and a temperature range of -55 to +165 °C. For the CFD230U raw coaxial cable, the FEP jacket must be considered in environmental, material-compatibility, and installation assessments. The compact 2.20 mm profile of the CFD230U 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 CFD230U RF coaxial cable.

Upper-Band Loss and RF Power

The band-edge specification at 67 GHz defines 6.019 dB/m attenuation together with 0.028 kW power capacity. Its center conductor is silver plated copper with a diameter of 0.51 mm; propagation velocity is specified at 76%. For the CFD230U 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 CFD230U RF coaxial cable at the intended operating frequency.

Where Wideband Flexible Routing Matters

These characteristics support the use of the CFD230U coaxial cable in compact test interconnects and broadband RF modules, provided the final assembly design respects the stated bend and power limits. For the CFD230U coaxial cable, this documented specification set enables disciplined comparison against alternative cable diameters and performance classes. When alternatives to the CFD230U 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 CFD230U 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 CFD230U raw coax.
