26.5 GHz Semi-Rigid High-Temperature Ultra-Low-Loss RF Coaxial Cable – CRM141UMDS

Thermally Stable 26.5 GHz Semi-Rigid Cable for Efficient Signal Transfer

The CRM141UMDS RF coaxial cable provides a characterized 26.5 GHz cable platform for low-loss radar paths and related microwave interconnects. Within the CRM141UMDS 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 CRM141UMDS coaxial cable with other Phase-Stable Semi-Rigid Coaxial Cables models should be based on the endpoint loss, power, conductor, and mechanical data below.

Phase and Propagation Design Inputs

Endpoint performance at 26.5 GHz is specified as 1.681 dB/m attenuation with 0.206 kW power handling. The transmission line incorporates a 1.05 mm silver plated copper center conductor, while the specified velocity of propagation is 81%. For the CRM141UMDS 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 CRM141UMDS RF coaxial cable at the intended operating frequency.

Stable Geometry for Low-Loss Distribution

Installation design should accommodate the 3.58 mm outer diameter and 13.50 mm static bend requirement throughout the -55 to +250 °C operating range. During installation of the CRM141UMDS raw coaxial cable, routing should remain within the specified bend geometry throughout forming, connectorization, and installation. The 3.58 mm geometry of the CRM141UMDS 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 CRM141UMDS RF coaxial cable.

Stable Signal Distribution Across Thermal Change

System architects may consider the CRM141UMDS coaxial cable for high-temperature RF modules and precision receivers when the specified frequency, loss, power, and bend limits satisfy the design margin. For the CRM141UMDS coaxial cable, this combination of characterized electrical performance and explicit routing limits supports repeatable engineering integration. When alternatives to the CRM141UMDS raw coaxial cable are required, additional construction and performance options are available in the Semi-Rigid Coaxial Cables portfolio.
