Ultra Low Loss 18 GHz Precision Test Coaxial Cable with PFA Jacket – Model CFS810

Ultra-Low-Loss Coaxial Cable for High-Power, Precision RF Measurement

The CFS810 ultra-low-loss precision test coaxial cable is engineered for applications requiring exceptional phase stability, low attenuation, and high power endurance. With a 50 Ω impedance and operation up to 18 GHz, it provides highly consistent electrical and mechanical performance for RF laboratories, calibration systems, and advanced microwave test environments. Fully REACH and RoHS compliant, it delivers professional-grade accuracy with verified environmental and safety standards.

Outstanding Electrical Consistency and Power Handling

The CFS810 coaxial cable integrates a solid silver-plated copper inner conductor (2.40 mm) and LD-PTFE dielectric, achieving minimal insertion loss and superior impedance stability. Attenuation remains extremely low—just 0.137 dB/m @ 1 GHz and 0.633 dB/m @ 18 GHz—while supporting average power up to 6.1 kW @ 100 MHz and 1.9 kW @ 1 GHz. Phase deviation stays within ±2° @ 10 GHz and ±3° @ 18 GHz, with amplitude variation ≤ ±0.1 dB @ 18 GHz. Its phase stability is maintained below 750 PPM from –55 °C to +85 °C, ensuring long-term measurement reliability under thermal fluctuation.

Reinforced Mechanical Design and Shielding Integrity

Encased in a 8.10 mm PFA jacket, the CFS810 cable offers excellent chemical resistance, thermal endurance, and flexibility for repeated test operations. Its dual silver-plated copper shielding provides > 90 dB electromagnetic isolation, minimizing interference and ensuring phase accuracy under movement. With a 40 mm single-bend radius, 81 mm repeated-bend radius, and 140 g/m weight, it offers high durability and handling stability for high-power laboratory applications. The cable withstands up to 2500 VDC, maintaining insulation reliability even under extended test cycles.

Applications Requiring High Power and Low Attenuation

The CFS810 ultra-low-loss coaxial cable is ideal for metrology-grade RF measurement, radar calibration, satellite communication testing, and 5 G validation systems. Its combination of high power capacity, phase stability, and mechanical strength ensures precise and consistent performance for both fixed and semi-flexible installations.
