Description
The CMG250 semi-flexible, low-loss coaxial cable is engineered for high-performance RF and microwave transmission up to 18 GHz . Featuring a large-diameter silver-plated copper or copper-clad steel inner conductor, precision PTFE dielectric, and a rugged tinned copper braided outer conductor, the CMG250 delivers excellent signal integrity, strong shielding, and dependable mechanical flexibility for demanding RF assemblies and instrumentation systems.
The CMG250 coaxial cable maintains a 50 Ω ±1.1 Ω characteristic impedance and provides stable wideband transmission up to its 18 GHz operating frequency . A 70% velocity of propagation, 4.7 ns/m time delay, and 95 pF/m capacitance ensure consistent phase behavior for precision RF paths. Attenuation remains low across the band—from 0.168 dB/m at 500 MHz to 1.421 dB/m at 18 GHz—supporting efficient high-frequency signal delivery. Shielding effectiveness above 100 dB protects against EMI for clean, low-distortion signal transmission.
Constructed with a robust 6.20 mm tinned copper braid, the CMG250 provides strong mechanical durability and semi-flex formability suitable for routing inside RF modules, airborne electronics, and tightly integrated microwave assemblies . A generous 30.00 mm single-bend radius allows secure installation without compromising electrical performance. Operating across −55 °C to +125 °C, the cable meets the thermal requirements of aerospace, industrial, and advanced communication environments.
The CMG250 semi-flex coaxial cable is ideal for 18 GHz instrumentation, radar subassemblies, communication modules, microwave test platforms, and RF systems requiring stable performance with flexible routing. As part of Mechanc’s Low-Loss Semi-Flexible Coaxial Cable Series, it delivers dependable electrical characteristics for R&D, production, and high-frequency integration.
Manufactured by Mechanc Shanghai Information Technology, the CMG250 semi-flexible coaxial cable offers low-loss transmission, strong shielding, and reliable mechanical durability for RF and microwave applications up to 18 GHz. REACH & RoHS compliant.
