40 GHz Semi-Flexible Low-Price RF Coaxial Cable – CMG047UM

Ultra-Compact 40 GHz Semi-Flexible Cable for Dense Microwave Assemblies

The CMG047UM RF coaxial cable is a purpose-engineered cable for compact microwave modules, specified for RF transmission through 40 GHz. Within the CMG047UM 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 CMG047UM 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.

Compact-Cable Electrical Trade-offs

At full rated bandwidth, the cable exhibits a specified attenuation of 11.271 dB/m and supports 0.002 kW of RF power. The transmission line incorporates a 0.29 mm silver plated copper clad steel center conductor, while the specified velocity of propagation is 70%. For the CMG047UM 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 CMG047UM RF coaxial cable at the intended operating frequency.

Ultra-Compact Geometry Inside RF Modules

For routing and packaging, the relevant limits are 1.19 mm outside diameter, 4.00 mm static bend radius, and -65 to +150 °C operating temperature. During installation of the CMG047UM raw coaxial cable, routing should remain within the specified bend geometry throughout forming, connectorization, and installation. The subminiature 1.19 mm profile of the CMG047UM 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 CMG047UM RF coaxial cable.

Dense Microwave Hardware at 40 GHz

Its defined operating envelope supports technical assessment for internal chassis routing and prototype RF hardware without extrapolating from family-level data. For the CMG047UM coaxial cable, accordingly, the cable can be evaluated at component, assembly, and system level using traceable product-specific parameters. When alternatives to the CMG047UM raw coaxial cable are required, additional construction and performance options are available in the Semi-Flexible Coaxial Cables portfolio.

Mechanc Shanghai Information Technology Co., Ltd. documents the CMG047UM 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 CMG047UM raw coax.
