40 GHz Flexible Ultra-Low-Loss RF Coaxial Cable – CFD360

Low-Attenuation 40 GHz Flexible Cable for Stable Microwave Interconnects

The electrical and mechanical architecture of the CFD360 RF coaxial cable supports compact test interconnects at frequencies up to 40 GHz. Within the CFD360 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 CFD360 coaxial cable with other Flexible Ultra-Low-Loss Coaxial Cables models should be based on the endpoint loss, power, conductor, and mechanical data below.

Signal Transfer at Maximum Frequency

At 40 GHz, the published transmission data specify a loss of 2.557 dB/m and a power rating of 0.075 kW. A 0.91 mm silver plated copper inner conductor establishes the conductive path, with a documented propagation velocity of 76%. For the CFD360 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 CFD360 RF coaxial cable at the intended operating frequency.

Design Scenarios Suited to Stable 40 GHz Paths

The CFD360 coaxial cable can be assessed for broadband RF modules and millimeter-wave instrumentation using the specified attenuation, propagation, thermal, and routing data. For the CFD360 coaxial cable, accordingly, the cable can be evaluated at component, assembly, and system level using traceable product-specific parameters. When alternatives to the CFD360 raw coaxial cable are required, additional construction and performance options are available in the Flexible Coaxial Cables portfolio.

Bend Control in Stable Microwave Layouts

For routing and packaging, the relevant limits are 3.60 mm outside diameter, 18.00 mm static bend radius and 36.00 mm minimum dynamic bend radius, and -55 to +165 °C operating temperature. For the CFD360 raw coaxial cable, the FEP jacket must be considered in environmental, material-compatibility, and installation assessments. The 3.60 mm geometry of the CFD360 RF cable balances packaging efficiency with the conductor cross-section required by its electrical performance class. Compliance with these constraints helps protect impedance continuity and repeatability at the cable-to-connector transition associated with the CFD360 RF coaxial cable.

Mechanc Shanghai Information Technology Co., Ltd. documents the CFD360 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 CFD360 raw coax.
