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

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

The CMG086U semi-flexible, low-loss coaxial cable is designed for wideband RF and microwave transmission up to 40 GHz . It features a silver-plated copper inner conductor, precision PTFE dielectric, and a robust tinned copper braided outer conductor that together ensure stable electrical performance, strong shielding, and reliable flexibility. Engineered for high-frequency modules, radar subsystems, and advanced test platforms, the CMG086U provides consistent signal integrity in both R&D and production environments.

Stable Electrical Performance for High-Frequency Signal Integrity

The CMG086U coaxial cable maintains a 50 Ω ±1.1 Ω characteristic impedance and delivers clean, predictable 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 stable phase behavior across high-frequency paths. Attenuation ranges from 0.262 dB/m at 500 MHz to 6.331 dB/m at 40 GHz, supporting short-run interconnects in precision RF systems. A shielding effectiveness above 100 dB minimizes interference for consistent, low-distortion signal transmission.

Flexible Construction with Strong Thermal and Mechanical Durability

Constructed with a 2.17 mm tinned copper braid, the CMG086U provides excellent flexibility and mechanical strength for repeated routing and precise positioning inside RF assemblies . The cable supports an 8.00 mm single-bend radius, allowing compact installation in densely populated microwave modules. Operating reliably from −55 °C to +150 °C, it withstands elevated thermal demands found in aerospace, industrial, and communication environments.

Applications Requiring Flexible, Low-Loss RF Performance

The CMG086U semi-flex coaxial cable is ideal for 40 GHz test systems, phased-array modules, radar instrumentation, wideband communication systems, and microwave assemblies requiring flexible routing with stable electrical performance. Part of Mechanc’s Low-Loss Semi-Flexible Coaxial Cable Series, it offers dependable high-frequency performance for prototyping, integration, and production.

Manufactured by Mechanc Shanghai Information Technology, the CMG086U semi-flexible coaxial cable provides strong shielding, low-loss transmission, and excellent flexibility for RF and microwave applications up to 40 GHz. REACH & RoHS compliant.
