Description

Low-Loss Semi-Rigid RF Cable with High Power and Shielding Efficiency

The CRG250 low-loss semi-rigid coaxial cable is designed for high-power RF and microwave transmission systems demanding exceptional shielding and structural stability. Operating up to 18 GHz with a 50 Ω impedance, it ensures precise impedance control and low attenuation for test, radar, and communication systems. Explore the CRG Series – Low-Loss Semi-Rigid Coaxial Cables for other diameters and frequency ranges.

Seamless Annealed Copper Tube and Silver-Plated Conductor

The CRG250 cable incorporates a 1.78 mm silver-plated copper inner conductor, PTFE dielectric, and a 6.35 mm seamless annealed copper outer conductor plated with a corrosion-resistant ternary alloy. This robust metallic structure provides >165 dB shielding effectiveness and stable phase characteristics under mechanical stress, ensuring long-term reliability in fixed installations.

Low Attenuation and High Power Handling

Delivering attenuation as low as 0.099 dB/m @ 300 MHz and 0.862 dB/m @ 18 GHz, the CRG250 supports average power up to 1.53 kW @ 300 MHz and 0.175 kW @ 18 GHz. Its velocity of propagation 76% and minimum bend radius 32 mm enable efficient routing in high-power assemblies without compromising performance.

Wide Temperature Range and Mechanical Integrity

Built for extreme environments, the CRG250 maintains electrical stability and mechanical strength from –55 °C to +250 °C. The semi-rigid copper structure prevents deformation under vibration or heat, ensuring reliable RF transmission in laboratory, aerospace, and defense applications.
