18 GHz Semi-Rigid High-Temperature Ultra-Low-Loss RF Coaxial Cable – CRM086DS

Ultra-Low-Loss 18 GHz Semi-Rigid Cable for Hot-Zone RF Routing

The CRM086DS RF coaxial cable addresses the signal-path requirements of high-temperature RF modules, offering characterized operation through 18 GHz. Within the CRM086DS raw coaxial cable configuration, the CRM geometry combines high-temperature capability with a higher propagation factor, supporting efficient fixed paths in demanding microwave assemblies. Quantitative comparison of the CRM086DS coaxial cable with other Phase-Stable Semi-Rigid Coaxial Cables models should be based on the endpoint loss, power, conductor, and mechanical data below.

Compact Fixed Paths with Thermal Headroom

Mechanical integration is governed by a 2.18 mm cable diameter, a 7.00 mm minimum static bend radius, and a temperature range of -55 to +250 °C. During installation of the CRM086DS raw coaxial cable, routing should remain within the specified bend geometry throughout forming, connectorization, and installation. The compact 2.18 mm profile of the CRM086DS RF cable facilitates constrained routing without relaxing the specified bend limits. Compliance with these constraints helps protect impedance continuity and repeatability at the cable-to-connector transition associated with the CRM086DS RF coaxial cable.

Ultra-Low-Loss Data for Fixed Paths

At 18 GHz, the published transmission data specify a loss of 2.389 dB/m and a power rating of 0.059 kW. A 0.59 mm silver plated copper inner conductor establishes the conductive path, with a documented propagation velocity of 81%. For the CRM086DS RF cable, the 81% 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 CRM086DS RF coaxial cable at the intended operating frequency.

Hot-Zone Receiver and Sensor Interconnects

The CRM086DS coaxial cable can be assessed for precision receivers and stable microwave distribution using the specified attenuation, propagation, thermal, and routing data. For the CRM086DS coaxial cable, this documented specification set enables disciplined comparison against alternative cable diameters and performance classes. When alternatives to the CRM086DS 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 CRM086DS 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 CRM086DS raw coax.
