0.047″ Semi-Flexible Low-Loss RF Coaxial Cable, 40 GHz Rated

Semi-Flexible Low-Loss Coaxial Cable for 40 GHz RF and Microwave Applications

The CMG047U semi-flexible, low-loss coaxial cable is designed for high-frequency RF and microwave transmission up to 40 GHz . Its silver-plated copper or copper-clad steel inner conductor, precision PTFE dielectric, and tinned copper braided outer conductor deliver reliable signal integrity, strong shielding performance, and excellent flexibility for compact routing. Engineered for next-generation microwave modules and test setups, the CMG047U provides stable electrical characteristics for both R&D and production environments.

Stable Electrical Performance for High-Frequency Signal Integrity

The CMG047U coaxial cable maintains a 50 Ω ±1.1 Ω impedance and provides clean, controlled transmission up to its 40 GHz operating frequency . With a 70% velocity of propagation, 4.7 ns/m time delay, and a capacitance of 95 pF/m, the cable ensures predictable phase behavior across wideband microwave signals. Attenuation performance reaches 11.065 dB/m at 40 GHz, supporting short, precise interconnects in high-frequency modules and instrumentation. Shielding effectiveness greater than 100 dB minimizes interference, ensuring stable operation in sensitive RF environments.

Flexible Construction with Extended Bend Endurance

Built with a 1.19 mm tinned copper braid, the CMG047U offers high flexibility while maintaining strong mechanical stability . A tight 4.00 mm single-bend radius and a 20.00 mm repeated-bend radius allow the cable to be routed in compact assemblies without compromising electrical performance. Its operating temperature range of −55 °C to +125 °C makes it suitable for aerospace, industrial electronics, and advanced microwave systems requiring dependable environmental resistance.

Applications Requiring Flexible, High-Frequency Low-Loss Coax

The CMG047U semi-flex coaxial cable is ideal for 40 GHz test systems, wideband communication modules, radar subassemblies, microwave instrumentation, and RF applications requiring both flexibility and high-frequency stability. Part of Mechanc’s Low-Loss Semi-Flexible Coaxial Cable Series, it provides consistent, low-loss performance for integration, prototyping, and production environments.

Manufactured by Mechanc Shanghai Information Technology, the CMG047U semi-flexible coaxial cable delivers reliable signal integrity, strong shielding, and excellent flexibility for RF and microwave applications up to 40 GHz. REACH & RoHS compliant.
