40 GHz Flexible Temperature Phase-Stable RF Coaxial Cable – CFN220

Thermally Stable 40 GHz Flexible Cable for Phase-Sensitive RF Systems

Designed for measurement reference paths, the CFN220 RF coaxial cable combines a 40 GHz upper-frequency limit with a controlled cable geometry. Within the CFN220 raw coaxial cable configuration, the CFN platform emphasizes controlled electrical length as ambient temperature changes, supporting repeatable phase relationships between signal paths. Quantitative comparison of the CFN220 coaxial cable with other Flexible Phase-Stable Coaxial Cables models should be based on the endpoint loss, power, conductor, and mechanical data below.

Phase-Sensitive Systems That Benefit Most

For phase-matched assemblies or antenna arrays, the CFN220 coaxial cable provides the quantitative inputs required for insertion-loss, delay, thermal, and mechanical integration reviews. For the CFN220 coaxial cable, the available data allow RF engineers to assess the cable against link margin, phase delay, thermal exposure, and packaging constraints. When alternatives to the CFN220 raw coaxial cable are required, additional construction and performance options are available in the Flexible Coaxial Cables portfolio.

Frequency Ceiling and Transmission Figures

For link-budget calculations at the 40 GHz operating limit, use 4.704 dB/m attenuation and 0.023 kW power handling. The conductor system uses silver plated copper at 0.51 mm diameter and provides a specified velocity of propagation of 82%. For the CFN220 RF cable, specified phase stability is ≤300 PPM @ -40 ~ +60 ℃, providing a defined input for phase-error allocation under the stated test condition. Together, these values support link-loss, electrical-delay, and power-margin calculations for the CFN220 RF coaxial cable at the intended operating frequency.

Cable Envelope for Phase-Matched Runs

The cable envelope measures 2.20 mm in diameter; the minimum static radius is 9.00 mm and 22.00 mm minimum dynamic bend radius, and the specified service range is -55 to +165 °C. For the CFN220 raw coaxial cable, the FEP jacket must be considered in environmental, material-compatibility, and installation assessments. The compact 2.20 mm profile of the CFN220 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 CFN220 RF coaxial cable.

Mechanc Shanghai Information Technology Co., Ltd. documents the CFN220 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 CFN220 raw coax.
