18 GHz Semi-Flexible Low-Price RF Coaxial Cable – CMG047

Miniature 18 GHz Semi-Flexible Cable for Space-Limited RF Modules

Developed for space-constrained instruments, the CMG047 RF coaxial cable offers a defined electrical bandwidth of up to 18 GHz. Within the CMG047 raw coaxial cable configuration, the CMG semi-flexible format can be formed into compact paths while retaining more routing control than a conventional highly flexible cable. Quantitative comparison of the CMG047 coaxial cable with other Low-Loss CMG Semi-Flexible Coaxial Cables models should be based on the endpoint loss, power, conductor, and mechanical data below.

Module-Level Uses for the Smallest CMG Option

System architects may consider the CMG047 coaxial cable for compact microwave modules and internal chassis routing when the specified frequency, loss, power, and bend limits satisfy the design margin. For the CMG047 coaxial cable, this documented specification set enables disciplined comparison against alternative cable diameters and performance classes. When alternatives to the CMG047 raw coaxial cable are required, additional construction and performance options are available in the Semi-Flexible Coaxial Cables portfolio.

Signal-Path Metrics at Rated Frequency

Endpoint performance at 18 GHz is specified as 6.035 dB/m attenuation with 0.007 kW power handling. Electrical construction is based on a 0.29 mm silver plated copper clad steel center conductor and a 70% propagation-velocity specification. For the CMG047 RF cable, the 70% 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 CMG047 RF coaxial cable at the intended operating frequency.

Forming a Miniature Semi-Flexible Path

Mechanical integration is governed by a 1.19 mm cable diameter, a 4.00 mm minimum static bend radius, and a temperature range of -65 to +150 °C. During installation of the CMG047 raw coaxial cable, routing should remain within the specified bend geometry throughout forming, connectorization, and installation. The subminiature 1.19 mm profile of the CMG047 RF cable supports dense RF packaging, while requiring controlled forming and termination practices. Compliance with these constraints helps protect impedance continuity and repeatability at the cable-to-connector transition associated with the CMG047 RF coaxial cable.

Mechanc Shanghai Information Technology Co., Ltd. documents the CMG047 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 CMG047 raw coax.
