High-Power 18GHz Low-Loss RF Coaxial Cable – Model CFP760

High-Power Low-Loss Cable for Maximum RF Energy and Stability

The CFP760 high-power low-loss coaxial cable is a heavy-duty option within the CFP family, engineered for RF and microwave systems that demand exceptional current capacity, low attenuation, and long-term thermal stability. Operating up to 18 GHz with a 50 Ω impedance, it delivers consistent performance under extreme load conditions. For additional diameters and even higher power handling, the CFP range scales above this model—up to CFP1500—within the CFP Series – High-Power Low-Loss Coaxial Cables.

Solid Core and Advanced Six-Layer Shielding Structure

The CFP760 coaxial cable integrates a solid silver-plated copper inner conductor (2.06 mm) with a low-density PTFE dielectric (5.89 mm) for optimal impedance consistency and power transfer. Its six-layer construction—silver-plated copper ribbon, high-temperature aluminum foil, copper braid, and FEP jacket—provides outstanding signal stability and superior heat dissipation. Attenuation remains low at 0.45 dB/m @ 1 GHz and 0.83 dB/m @ 18 GHz, while average power handling reaches 1.53 kW @ 100 MHz.

Excellent Shielding and Environmental Resistance

Delivering > 100 dB EMI suppression, the CFP760 cable ensures distortion-free performance in high-field RF environments. Its 7.62 mm FEP jacket withstands temperatures from –55 °C to +200 °C while maintaining exceptional chemical and mechanical durability. The 38 mm single-bend and 76 mm repeated-bend radii support safe routing and extended service life.

Applications Requiring Extreme Power and Long-Term Reliability

The CFP760 high-power coaxial cable is designed for power-intensive transmission lines, amplifier test benches, and long-duration system integration. Its 2000 V DC voltage withstand, > 100 dB shielding, and phase stability within ±5° @ 18 GHz guarantee reliable, repeatable results across extended operational cycles. Compatible with rugged RF connectors such as N-type and TNC interfaces, it ensures stable coupling and minimal return loss in high-power microwave installations.

Manufactured by Mechanc Shanghai Information Technology Co., Ltd., the CFP760 high-power low-loss coaxial cable combines solid-core precision, multilayer shielding, and verified REACH and RoHS compliance—delivering maximum efficiency, thermal endurance, and signal integrity for high-power RF and microwave applications.
