18 GHz Semi-Rigid High-Temperature Phase-Stable RF Coaxial Cable – CRG141DS

High-Power 18 GHz Semi-Rigid Cable for Elevated-Temperature RF Systems

The CRG141DS RF coaxial cable is engineered for hot-zone instrumentation, with a specified operating range extending to 18 GHz. Within the CRG141DS 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 CRG141DS 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-Capable Geometry for Warm Environments

The cable envelope measures 3.58 mm in diameter; the minimum static radius is 15.00 mm, and the specified service range is -55 to +250 °C. During installation of the CRG141DS raw coaxial cable, routing should remain within the specified bend geometry throughout forming, connectorization, and installation. The 3.58 mm geometry of the CRG141DS 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 CRG141DS RF coaxial cable.

Loss Control at the Frequency Limit

Endpoint performance at 18 GHz is specified as 1.503 dB/m attenuation with 0.236 kW power handling. The conductor system uses silver plated copper at 0.99 mm diameter and provides a specified velocity of propagation of 76%. For the CRG141DS 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 CRG141DS RF coaxial cable at the intended operating frequency.

Power-Oriented RF Hardware in Elevated Temperatures

System architects may consider the CRG141DS coaxial cable for radar electronics and industrial sensing hardware when the specified frequency, loss, power, and bend limits satisfy the design margin. For the CRG141DS coaxial cable, the available data allow RF engineers to assess the cable against link margin, phase delay, thermal exposure, and packaging constraints. When alternatives to the CRG141DS 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 CRG141DS 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 CRG141DS raw coax.
