18 GHz Semi-Rigid High-Temperature Phase-Stable RF Coaxial Cable – CRG047DS

Miniature 18 GHz High-Temperature Semi-Rigid Cable for Precise Routing

The CRG047DS RF coaxial cable provides a characterized 18 GHz cable platform for hot-zone instrumentation and related microwave interconnects. Within the CRG047DS 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 CRG047DS coaxial cable with other High-Temperature Semi-Rigid Coaxial Cables models should be based on the endpoint loss, power, conductor, and mechanical data below.

Precision Forming in Hot-Zone Hardware

The mechanical specification combines a 1.15 mm profile with a 5.80 mm minimum static radius and qualified operation from -55 to +125 °C. During installation of the CRG047DS raw coaxial cable, routing should remain within the specified bend geometry throughout forming, connectorization, and installation. The subminiature 1.15 mm profile of the CRG047DS 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 CRG047DS RF coaxial cable.

Endpoint Performance for Thermal Environments

The band-edge specification at 18 GHz defines 5.220 dB/m attenuation together with 0.032 kW power capacity. Electrical construction is based on a 0.30 mm silver plated copper clad steel center conductor and a 76% propagation-velocity specification. For the CRG047DS 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 CRG047DS RF coaxial cable at the intended operating frequency.

High-Temperature Uses for a Miniature Fixed Cable

These characteristics support the use of the CRG047DS coaxial cable in radar electronics and industrial sensing hardware, provided the final assembly design respects the stated bend and power limits. For the CRG047DS coaxial cable, its product-level parameters provide a practical basis for cable selection, assembly design, and technical verification. When alternatives to the CRG047DS raw coaxial cable are required, additional construction and performance options are available in the Semi-Rigid Coaxial Cables portfolio.

Mechanc Shanghai Information Technology Co., Ltd. documents the CRG047DS 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 CRG047DS raw coax.
