40 GHz Ultra-Low-Loss Precision Test RF Coaxial Cable – CFS360A

Ultra-Low-Loss 40 GHz Precision Test Cable for Repeatable Measurements

The CFS360A RF coaxial cable is engineered for repeatable microwave measurements, with a specified operating range extending to 40 GHz. Within the CFS360A raw coaxial cable configuration, the CFS family is intended for precision test paths where attenuation, delay and bend management directly influence measurement repeatability. Quantitative comparison of the CFS360A coaxial cable with other Ultra-Low-Loss CFS Precision Test Cables models should be based on the endpoint loss, power, conductor, and mechanical data below.

Measurement Setups That Need Repeatable Low Loss

The documented performance envelope is relevant to vector network analyzer setups and RF calibration benches, where cable loss and routing geometry must be evaluated together. For the CFS360A coaxial cable, its product-level parameters provide a practical basis for cable selection, assembly design, and technical verification. When alternatives to the CFS360A raw coaxial cable are required, additional construction and performance options are available in the Precision Test Coaxial Cables portfolio.

Measured-Path Planning Data

The maximum-frequency operating point is characterized by 2.557 dB/m loss and 0.075 kW power capability at 40 GHz. Its center conductor is silver plated copper with a diameter of 0.91 mm; propagation velocity is specified at 81%. For the CFS360A RF cable, the 81% 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 CFS360A RF coaxial cable at the intended operating frequency.

Precision-Test Routing and Bend Discipline

The mechanical specification combines a 3.60 mm profile with a 18.00 mm minimum static radius and 36.00 mm minimum dynamic bend radius and qualified operation from -55 to +165 °C. For the CFS360A raw coaxial cable, the FEP jacket must be considered in environmental, material-compatibility, and installation assessments. The 3.60 mm geometry of the CFS360A 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 CFS360A RF coaxial cable.

Mechanc Shanghai Information Technology Co., Ltd. documents the CFS360A 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 CFS360A raw coax.
