40 GHz Flexible Temperature Phase-Stable RF Coaxial Cable – CFN400

Phase-Controlled 40 GHz Flexible Cable for Wider-Bore RF Installations

The CFN400 RF coaxial cable addresses the signal-path requirements of phase-matched assemblies, offering characterized operation through 40 GHz. Within the CFN400 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 CFN400 coaxial cable with other Flexible Phase-Stable Coaxial Cables models should be based on the endpoint loss, power, conductor, and mechanical data below.

Electrical Limits for Link-Budget Work

The maximum-frequency operating point is characterized by 2.944 dB/m loss and 0.067 kW power capability at 40 GHz. Electrical construction is based on a 1.05 mm silver plated copper center conductor and a 82% propagation-velocity specification. For the CFN400 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 CFN400 RF coaxial cable at the intended operating frequency.

Larger-Diameter Routing with Thermal Awareness

Installation design should accommodate the 4.00 mm outer diameter and 20.00 mm static bend requirement and 40.00 mm minimum dynamic bend radius throughout the -55 to +165 °C operating range. For the CFN400 raw coaxial cable, the FEP jacket must be considered in environmental, material-compatibility, and installation assessments. The 4.00 mm geometry of the CFN400 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 CFN400 RF coaxial cable.

Applications Requiring Thermal Phase Control

The documented performance envelope is relevant to antenna arrays and thermal test chambers, where cable loss and routing geometry must be evaluated together. For the CFN400 coaxial cable, this combination of characterized electrical performance and explicit routing limits supports repeatable engineering integration. When alternatives to the CFN400 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 CFN400 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 CFN400 raw coax.
