Engineered for High-Power RF Transmission

The CFP460 coaxial cable integrates a silver-plated copper inner conductor (1.02 mm) with a low-density PTFE dielectric (3.07 mm) and an internal aluminum foil barrier for improved heat dissipation. It supports average power up to 1.8 kW @ 100 MHz while maintaining attenuation as low as 0.35 dB/m @ 1 GHz and 1.583 dB/m @ 18 GHz. Phase stability and amplitude stability remain excellent, ensuring clean, repeatable measurements.

Durable FEP Jacket and Superior Shielding Effectiveness

Encased in a 4.60 mm FEP jacket, the CFP460 cable provides outstanding resistance to heat, abrasion, and chemicals across –55 °C to +200 °C. Its triple-layer shielding—silver-plated copper ribbon, aluminum foil, and copper braid—achieves > 100 dB EMI suppression for uninterrupted high-power transmission. The 23 mm single-bend and 46 mm repeated-bend radii ensure long mechanical life and reliable installation. For a complete overview of compatible designs, visit the Low-Loss Coaxial Cable Series.

Applications Requiring High Power and Thermal Stability

The CFP460 high-power coaxial cable is ideal for radar transmitters, RF amplifiers, and high-energy test benches where both electrical stability and thermal endurance are critical. Its 1000 V DC rating and > 100 dB shielding effectiveness support precision, distortion-free signal transmission. Compatible with rugged RF connectors such as N-type and TNC interfaces, it guarantees secure, low-reflection coupling for high-performance test environments.

Manufactured by Mechanc Shanghai Information Technology Co., Ltd., the CFP460 high-power low-loss coaxial cable combines reliable power capacity, superior thermal performance, and verified REACH and RoHS compliance—delivering durable, precision-grade transmission for demanding RF and microwave applications.
