18 GHz Semi-Rigid High-Temperature Phase-Stable RF Coaxial Cable – CRG250UDS

Low-Attenuation 18 GHz Semi-Rigid Cable for High-Temperature Power Paths

Designed for aerospace RF modules, the CRG250UDS RF coaxial cable combines a 18 GHz upper-frequency limit with a controlled cable geometry. Within the CRG250UDS 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 CRG250UDS coaxial cable with other High-Temperature Semi-Rigid Coaxial Cables models should be based on the endpoint loss, power, conductor, and mechanical data below.

Thermal-Range Transmission Characteristics

The band-edge specification at 18 GHz defines 0.861 dB/m attenuation together with 0.308 kW power capacity. Its center conductor is silver plated copper with a diameter of 1.78 mm; propagation velocity is specified at 76%. For the CRG250UDS 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 CRG250UDS RF coaxial cable at the intended operating frequency.

Routing Low-Attenuation Cable Through Hot Areas

The 6.35 mm outside diameter requires a minimum static bend radius of 32.00 mm, with operation specified across -55 to +250 °C. During installation of the CRG250UDS raw coaxial cable, routing should remain within the specified bend geometry throughout forming, connectorization, and installation. The 6.35 mm cross-section of the CRG250UDS RF cable prioritizes loss and power performance over minimum routing volume. Compliance with these constraints helps protect impedance continuity and repeatability at the cable-to-connector transition associated with the CRG250UDS RF coaxial cable.

Low-Attenuation Thermal Routes Through 18 GHz

These characteristics support the use of the CRG250UDS coaxial cable in hot-zone instrumentation and radar electronics, provided the final assembly design respects the stated bend and power limits. For the CRG250UDS coaxial cable, the result is a product-specific RF interconnect option supported by the electrical and mechanical data required for design review. When alternatives to the CRG250UDS 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 CRG250UDS 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 CRG250UDS raw coax.
