40 GHz Semi-Rigid Low-Price RF Coaxial Cable – CRE047UMDS

Compact 40 GHz Semi-Rigid Cable for Cost-Efficient Microwave Modules

For repeatable chassis layouts, the CRE047UMDS RF coaxial cable provides a technically defined transmission-line solution rated through 40 GHz. Within the CRE047UMDS raw coaxial cable configuration, the CRE family provides an economical semi-rigid format for fixed, repeatable paths inside filters, amplifiers and integrated microwave housings. Quantitative comparison of the CRE047UMDS coaxial cable with other Cost-Efficient Semi-Rigid Coaxial Cables models should be based on the endpoint loss, power, conductor, and mechanical data below.

Economical 40 GHz Module Interconnects

The CRE047UMDS coaxial cable can be assessed for fixed microwave modules and filter and amplifier interconnects using the specified attenuation, propagation, thermal, and routing data. For the CRE047UMDS coaxial cable, its product-level parameters provide a practical basis for cable selection, assembly design, and technical verification. When alternatives to the CRE047UMDS raw coaxial cable are required, additional construction and performance options are available in the Semi-Rigid Coaxial Cables portfolio.

Fixed-Route Electrical Performance

At 40 GHz, the published transmission data specify a loss of 8.373 dB/m and a power rating of 0.003 kW. The conductor system uses silver plated copper clad steel at 0.29 mm diameter and provides a specified velocity of propagation of 70%. For the CRE047UMDS RF cable, the 70% 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 CRE047UMDS RF coaxial cable at the intended operating frequency.

Dense Module Layout with a Fixed RF Path

The mechanical specification combines a 1.19 mm profile with a 5.00 mm minimum static radius and qualified operation from -55 to +125 °C. During installation of the CRE047UMDS raw coaxial cable, routing should remain within the specified bend geometry throughout forming, connectorization, and installation. The subminiature 1.19 mm profile of the CRE047UMDS RF cable supports dense RF packaging, while requiring controlled forming and termination practices. Compliance with these constraints helps protect impedance continuity and repeatability at the cable-to-connector transition associated with the CRE047UMDS RF coaxial cable.

Mechanc Shanghai Information Technology Co., Ltd. documents the CRE047UMDS 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 CRE047UMDS raw coax.
