Ultra Low Loss 5.8 GHz Precision Test Coaxial Cable with FEP Jacket – Model CFS120

Ultra-Stable Coaxial Cable for High-Frequency RF Measurement Precision

The CFS120 ultra-low-loss precision test coaxial cable delivers superior electrical stability, low attenuation, and consistent phase performance for advanced RF and microwave testing environments. Designed for operation up to 67 GHz with a 50 Ω impedance, it ensures metrology-grade repeatability for vector network analyzer (VNA) calibration, 5G component testing, and precision laboratory applications. Fully REACH and RoHS compliant, it combines top-tier signal integrity with responsible engineering quality.

Reliable Electrical Performance for High-Precision Measurements

The CFS120 coaxial cable incorporates a solid silver-plated copper inner conductor and LD-PTFE dielectric that ensure excellent impedance uniformity and minimal signal distortion across its full frequency range. Attenuation remains exceptionally low—just 0.850 dB/m @ 18 GHz and 1.430 dB/m @ 40 GHz—while phase deviation stays within ±2° @ 10 GHz and ±3° @ 18 GHz. With thermal phase drift below 750 PPM between –55 °C and +85 °C, it provides highly consistent performance in fluctuating test environments, ensuring long-term repeatability and data accuracy.

Mechanical Robustness and Shielding Integrity

Encased in a 1.20 mm PFA jacket, the CFS120 cable combines thermal endurance, mechanical flexibility, and resistance to abrasion and chemical wear. Its dual silver-plated copper shielding achieves > 90 dB electromagnetic isolation, maintaining clean signal integrity in high-density test setups. The precision-balanced structure offers stable mechanical geometry that preserves consistent impedance and phase characteristics throughout repeated bending cycles.

Applications Requiring High Stability and Low Loss

The CFS120 ultra-low-loss coaxial cable is ideal for high-frequency testing, radar validation, 5G signal verification, and microwave calibration setups requiring ultra-low attenuation and tight phase control. Its solid-core design and durable PFA jacket provide dependable performance for both laboratory and production-grade testing.
