0.047″ Semi-Rigid Low-Loss RF Coaxial Cable, 26.5 GHz Rated

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

The CRG047 low-loss semi-rigid coaxial cable is engineered for precision RF and microwave transmission up to 26.5 GHz . Built with a silver-plated copper-clad steel inner conductor, PTFE dielectric, and a seamless annealed copper outer conductor with ternary alloy plating, the CRG047 provides excellent shielding performance, strong mechanical stability, and consistent impedance control. Designed for applications requiring formable coaxial routing, it supports high-temperature environments and ensures reliable high-frequency performance in compact RF assemblies.

Stable Electrical Performance for High-Frequency Signal Integrity

The CRG047 semi-rigid cable maintains a 50 Ω ±1.1 Ω characteristic impedance and provides reliable signal transmission up to its 26.5 GHz operating frequency . A 77% velocity of propagation ensures predictable phase behavior, while attenuation performance includes 6.024 dB/m at 26.5 GHz for short interconnects in sensitive RF systems. Its high shielding effectiveness of ≥165 dB protects against electromagnetic interference, supporting clean, low-distortion transmission required for advanced microwave circuits and subassemblies.

Rigid Copper Construction with Extended Temperature Endurance

Constructed with a 1.10 mm seamless annealed copper tube, the CRG047 offers excellent rigidity, dimensional stability, and the ability to be bent into fixed, repeatable cable paths without compromising electrical performance . The cable withstands temperatures from −55 °C to +250 °C, making it suitable for aerospace, instrumentation, and high-heat microwave environments. With a light weight of 8 g/m and a minimum bend radius of 4.00 mm, it supports compact internal routing within RF modules and tightly integrated systems.
