High-Power 18GHz Low-Loss RF Coaxial Cable – Model CFP640

High-Power Low-Loss Cable for Demanding RF and Microwave Applications

The CFP640 high-power low-loss coaxial cable is built for high-energy RF and microwave systems requiring exceptional power endurance, low attenuation, and consistent phase stability. Operating up to 18 GHz with a 50 Ω impedance, it delivers reliable transmission with minimal loss under continuous high-power conditions. Designed for both fixed and dynamic setups, the CFP640 ensures thermal reliability and amplitude precision in radar, defense, and communication test environments.

Solid Conductor and Six-Layer High-Power Design

The CFP640 coaxial cable uses a solid silver-plated copper inner conductor (1.57 mm) for superior current-carrying capacity and minimized resistive losses. Its six-layer structure—LD-PTFE dielectric, silver-plated copper ribbon, high-temperature aluminum foil, copper braid, and FEP jacket—ensures stable impedance and outstanding durability. Attenuation remains as low as 0.22 dB/m @ 1 GHz and 1.02 dB/m @ 18 GHz, supporting average power up to 2.05 kW @ 100 MHz while maintaining amplitude stability within ±0.1 dB @ 18 GHz.

Superior Shielding and Thermal Resistance

With > 100 dB EMI suppression, the CFP640 cable maintains distortion-free signal integrity in high-field environments. The 6.35 mm FEP jacket offers excellent flexibility, chemical resistance, and heat tolerance up to +200 °C. Its 31 mm single-bend and 63 mm repeated-bend radii guarantee mechanical reliability during installation or frequent motion.

Applications Requiring Maximum Power and Stability

The CFP640 high-power coaxial cable is ideal for high-energy transmitters, RF amplifiers, and industrial test setups operating across 0–18 GHz. Its 2000 V DC voltage rating, excellent phase control (≤ ±5° @ 18 GHz), and robust shielding structure ensure consistent performance under demanding conditions. Compatible with rugged RF connectors such as N-type and TNC interfaces, it delivers reliable coupling for high-current, low-loss operation.

Manufactured by Mechanc Shanghai Information Technology Co., Ltd., the CFP640 high-power low-loss coaxial cable combines solid-core conductivity, six-layer shielding integrity, and verified REACH and RoHS compliance — ensuring long-life, precision-grade performance for high-power RF and microwave applications.
