18 GHz Semi-Rigid High-Temperature Ultra-Low-Loss RF Coaxial Cable – CRM141DS

High-Power 18 GHz Semi-Rigid Cable with Ultra-Low-Loss Performance

With an upper operating frequency of 18 GHz, the CRM141DS RF coaxial cable is intended for stable microwave distribution where predictable interconnect behavior is required. Within the CRM141DS 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 CRM141DS coaxial cable with other Phase-Stable Semi-Rigid Coaxial Cables models should be based on the endpoint loss, power, conductor, and mechanical data below.

Efficient Power Transfer in Fixed Microwave Paths

The documented performance envelope is relevant to low-loss radar paths and high-temperature RF modules, where cable loss and routing geometry must be evaluated together. For the CRM141DS 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 CRM141DS raw coaxial cable are required, additional construction and performance options are available in the Semi-Rigid Coaxial Cables portfolio.

Efficient RF Transfer at Rated Bandwidth

The maximum-frequency operating point is characterized by 1.369 dB/m loss and 0.253 kW power capability at 18 GHz. Electrical construction is based on a 1.05 mm silver plated copper center conductor and a 81% propagation-velocity specification. For the CRM141DS 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 CRM141DS RF coaxial cable at the intended operating frequency.

Mechanical Fit for Efficient High-Power Transfer

The cable envelope measures 3.58 mm in diameter; the minimum static radius is 13.50 mm, and the specified service range is -55 to +250 °C. During installation of the CRM141DS raw coaxial cable, routing should remain within the specified bend geometry throughout forming, connectorization, and installation. The 3.58 mm geometry of the CRM141DS 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 CRM141DS RF coaxial cable.

Mechanc Shanghai Information Technology Co., Ltd. documents the CRM141DS 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 CRM141DS raw coax.
