40 GHz Flexible High-Temperature Phase-Stable RF Coaxial Cable – CFU360

High-Temperature 40 GHz Flexible Cable for Stable Microwave Routing

RF engineers can specify the CFU360 RF coaxial cable for temperature-cycled electronics requiring documented performance to 40 GHz. Within the CFU360 raw coaxial cable configuration, the CFU series combines flexible routing with a construction selected for phase-sensitive operation in equipment exposed to changing thermal conditions. Quantitative comparison of the CFU360 coaxial cable with other Flexible Phase-Stable Coaxial Cables models should be based on the endpoint loss, power, conductor, and mechanical data below.

Microwave Transmission Parameters

At 40 GHz, the published transmission data specify a loss of 3.888 dB/m and a power rating of 0.053 kW. Its center conductor is silver plated copper with a diameter of 0.72 mm; propagation velocity is specified at 76%. For the CFU360 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 CFU360 RF coaxial cable at the intended operating frequency.

Cable Dimensions for Thermally Active Equipment

Installation design should accommodate the 3.01 mm outer diameter and 18.00 mm static bend requirement and 36.00 mm minimum dynamic bend radius throughout the -55 to +125 °C operating range. During installation of the CFU360 raw coaxial cable, routing should remain within the specified bend geometry throughout forming, connectorization, and installation. The 3.01 mm geometry of the CFU360 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 CFU360 RF coaxial cable.

Thermal Test Systems Needing Flexible Routing

The CFU360 coaxial cable can be assessed for airborne RF systems and phase-sensitive instrumentation using the specified attenuation, propagation, thermal, and routing data. For the CFU360 coaxial cable, this combination of characterized electrical performance and explicit routing limits supports repeatable engineering integration. When alternatives to the CFU360 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 CFU360 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 CFU360 raw coax.
