Ultra Flexible and Ultra Low Loss 8 GHz Precision Test Coaxial Cable with PUR Jacket – Model CFS1200

Ultra-Low-Loss, High-Power Coaxial Cable for Demanding RF Applications

The CFS1200 ultra-low-loss precision test coaxial cable is engineered for high-power, low-attenuation performance in advanced RF and microwave testing systems. Operating up to 8 GHz with a 50 Ω impedance, it delivers stable phase and amplitude characteristics even under extreme thermal and mechanical conditions. Its large conductor structure enables superior power handling and minimal insertion loss, making it ideal for long-distance, high-energy precision test environments. The cable is fully REACH and RoHS compliant, ensuring top-tier environmental and quality assurance standards.

Outstanding Power Capacity and Electrical Stability

The CFS1200 coaxial cable integrates a solid silver-plated copper inner conductor (3.80 mm) with an LD-PTFE dielectric for maximum power efficiency and minimal signal degradation. Attenuation values remain extremely low—just 0.100 dB/m @ 1 GHz and 0.310 dB/m @ 8 GHz—while the cable handles up to 5.5 kW @ 100 MHz and 0.54 kW @ 8 GHz. Phase stability is maintained within ±2° @ 8 GHz, and amplitude variation stays within ±0.1 dB, ensuring consistent and repeatable performance across a wide temperature range of –55 °C to +85 °C. The 83 % velocity of propagation further enhances timing precision for high-frequency synchronization.

Heavy-Duty Mechanical Design and Superior Shielding

Encased in a 12.00 mm FEP jacket, the CFS1200 cable combines rugged durability with excellent thermal and chemical resistance. Its dual-layer silver-plated copper shielding achieves > 90 dB EMI suppression, guaranteeing clean, distortion-free transmission even in high-interference industrial or defense testing environments. With a 60 mm single-bend radius, 110 mm repeated-bend radius, and 4000 VDC dielectric withstand strength, this model provides exceptional mechanical reliability and long service life even under repeated bending and vibration.

Applications Requiring High Power and Long-Term Phase Stability

The CFS1200 ultra-low-loss coaxial cable is ideal for power amplifier testing, radar system calibration, antenna measurement ranges, and long-run VNA test setups where phase integrity and power endurance are critical. Its combination of ultra-low attenuation, strong shielding, and robust mechanical structure ensures precision under the most demanding laboratory and field conditions.
