26.5 GHz Semi-Rigid High-Temperature Phase-Stable RF Coaxial Cable – CRG141UDS

Thermally Durable 26.5 GHz Semi-Rigid Cable for Phase-Sensitive Hardware

For radar electronics, the CRG141UDS RF coaxial cable provides a technically defined transmission-line solution rated through 26.5 GHz. Within the CRG141UDS 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 CRG141UDS coaxial cable with other High-Temperature Semi-Rigid Coaxial Cables models should be based on the endpoint loss, power, conductor, and mechanical data below.

High-Temperature Signal-Path Metrics

At full rated bandwidth, the cable exhibits a specified attenuation of 1.877 dB/m and supports 0.189 kW of RF power. Electrical construction is based on a 0.99 mm silver plated copper center conductor and a 76% propagation-velocity specification. For the CRG141UDS 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 CRG141UDS RF coaxial cable at the intended operating frequency.

Phase-Sensitive Links with Thermal Durability

Its defined operating envelope supports technical assessment for industrial sensing hardware and aerospace RF modules without extrapolating from family-level data. For the CRG141UDS coaxial cable, this combination of characterized electrical performance and explicit routing limits supports repeatable engineering integration. When alternatives to the CRG141UDS raw coaxial cable are required, additional construction and performance options are available in the Semi-Rigid Coaxial Cables portfolio.

Phase-Aware Layout Under Thermal Stress

Installation design should accommodate the 3.58 mm outer diameter and 15.00 mm static bend requirement throughout the -55 to +250 °C operating range. During installation of the CRG141UDS raw coaxial cable, routing should remain within the specified bend geometry throughout forming, connectorization, and installation. The 3.58 mm geometry of the CRG141UDS 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 CRG141UDS RF coaxial cable.

Mechanc Shanghai Information Technology Co., Ltd. documents the CRG141UDS 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 CRG141UDS raw coax.
