26.5 GHz Ultra-Low-Loss Precision Test RF Coaxial Cable – CFS480T

High-Power 26.5 GHz Precision Test Cable with Low Attenuation

For vector network analyzer setups, the CFS480T RF coaxial cable provides a technically defined transmission-line solution rated through 26.5 GHz. Within the CFS480T 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 CFS480T 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.

High-Frequency Behaviour in Numbers

Endpoint performance at 26.5 GHz is specified as 1.308 dB/m attenuation with 0.193 kW power handling. A 1.40 mm silver plated copper inner conductor establishes the conductive path, with a documented propagation velocity of 83%. For the CFS480T RF cable, the 83% 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 CFS480T RF coaxial cable at the intended operating frequency.

Managing the Cable During High-Power Tests

The 5.10 mm outside diameter requires a minimum static bend radius of 26.00 mm and 51.00 mm minimum dynamic bend radius, with operation specified across -55 to +165 °C. For the CFS480T raw coaxial cable, the FEP jacket must be considered in environmental, material-compatibility, and installation assessments. The 5.10 mm cross-section of the CFS480T RF cable prioritizes loss and power performance over minimum routing volume. Compliance with these constraints helps protect impedance continuity and repeatability at the cable-to-connector transition associated with the CFS480T RF coaxial cable.

Test Benches Combining Power and Accuracy

System architects may consider the CFS480T coaxial cable for RF calibration benches and production verification when the specified frequency, loss, power, and bend limits satisfy the design margin. For the CFS480T coaxial cable, the result is a product-specific RF interconnect option supported by the electrical and mechanical data required for design review. When alternatives to the CFS480T raw coaxial cable are required, additional construction and performance options are available in the Precision Test Coaxial Cables portfolio.

Mechanc Shanghai Information Technology Co., Ltd. documents the CFS480T 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 CFS480T raw coax.
