0.141″ Semi-Flexible Low-Loss RF Coaxial Cable, 26.5 GHz Rated

Semi-Flexible Low-Loss Coaxial Cable for 26.5 GHz RF and Microwave Applications

The CMG141U semi-flexible, low-loss coaxial cable is engineered for wideband RF and microwave transmission up to 26.5 GHz . Built with a large-diameter silver-plated copper or copper-clad steel inner conductor, precision PTFE dielectric, and a rugged tinned copper braided outer conductor, the CMG141U provides excellent signal integrity, strong shielding, and reliable flexibility for demanding RF assemblies, instrumentation systems, and compact microwave modules.

Stable Electrical Performance for High-Frequency Signal Integrity

The CMG141U coaxial cable maintains a 50 Ω ±1.1 Ω characteristic impedance and delivers highly stable transmission up to its 26.5 GHz operating frequency . A 70% velocity of propagation, 4.7 ns/m time delay, and capacitance of 98 pF/m ensure predictable phase behavior across microwave paths. Attenuation remains low across the band—from 0.250 dB/m at 500 MHz to 3.075 dB/m at 26.5 GHz—supporting efficient signal delivery in high-frequency RF subsystems. Shielding effectiveness above 100 dB protects against electromagnetic interference for clean, low-distortion signal integrity.

Durable Semi-Flexible Construction with Thermal Stability

Constructed with a 3.55 mm tinned copper braid, the CMG141U offers strong mechanical stability and semi-flex formability suitable for routed internal connections in RF instruments and densely integrated systems . Supporting an 8.00 mm single-bend radius, the cable enables compact installation without compromising performance. Designed to operate across −55 °C to +125 °C, it meets the stringent thermal requirements of aerospace, industrial electronics, and high-frequency communication platforms.

Applications Requiring Flexible, Low-Loss RF Performance

The CMG141U semi-flex coaxial cable is ideal for 26.5 GHz test systems, microwave subassemblies, radar modules, wideband communication systems, and RF equipment requiring flexible routing with stable high-frequency performance. As part of Mechanc’s Low-Loss Semi-Flexible Coaxial Cable Series, it ensures dependable electrical charac
