40 GHz Semi-Rigid High-Temperature Phase-Stable RF Coaxial Cable – CRG047UMDS

Compact 40 GHz High-Temperature Semi-Rigid Cable for Dense RF Hardware

Developed for radar electronics, the CRG047UMDS RF coaxial cable offers a defined electrical bandwidth of up to 40 GHz. Within the CRG047UMDS raw coaxial cable configuration, the CRG range is differentiated by its +250 °C upper operating limit, making thermal placement a central part of system-level cable selection. Quantitative comparison of the CRG047UMDS coaxial cable with other High-Temperature Semi-Rigid Coaxial Cables models should be based on the endpoint loss, power, conductor, and mechanical data below.

Power Delivery and Attenuation Balance

At 40 GHz, the published transmission data specify a loss of 8.163 dB/m and a power rating of 0.020 kW. The transmission line incorporates a 0.30 mm silver plated copper clad steel center conductor, while the specified velocity of propagation is 76%. For the CRG047UMDS 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 CRG047UMDS RF coaxial cable at the intended operating frequency.

Dense Hot-Zone Microwave Assemblies

The CRG047UMDS coaxial cable can be assessed for industrial sensing hardware and aerospace RF modules using the specified attenuation, propagation, thermal, and routing data. For the CRG047UMDS 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 CRG047UMDS raw coaxial cable are required, additional construction and performance options are available in the Semi-Rigid Coaxial Cables portfolio.

Compact Semi-Rigid Geometry at Elevated Temperature

The 1.15 mm outside diameter requires a minimum static bend radius of 5.80 mm, with operation specified across -55 to +125 °C. During installation of the CRG047UMDS raw coaxial cable, routing should remain within the specified bend geometry throughout forming, connectorization, and installation. The subminiature 1.15 mm profile of the CRG047UMDS 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 CRG047UMDS RF coaxial cable.

Mechanc Shanghai Information Technology Co., Ltd. documents the CRG047UMDS 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 CRG047UMDS raw coax.
