Ultra Flexible and Ultra Low Loss 18 GHz Precision Test Coaxial Cable with PUR Jacket – Model CFS920MS

Flexible, Ultra-Low-Loss Coaxial Cable for Precision RF Measurement Systems

The CFS920MS ultra-low-loss precision test coaxial cable is engineered for test environments that demand outstanding electrical stability combined with superior flexibility. Its multi-fiber stranded silver-plated copper inner conductor provides enhanced mechanical endurance and bending resistance, making it ideal for setups where cables are frequently repositioned. Operating up to 18 GHz with a 50 Ω impedance, this model ensures consistent phase and amplitude stability for metrology-grade RF and microwave testing. Fully REACH and RoHS compliant, it meets global performance and sustainability standards.

Stable Electrical Performance with Flexible Construction

The CFS920MS coaxial cable combines low-loss LD-PTFE dielectric insulation with precision shielding and a stranded silver-plated copper conductor for improved flexibility and long-term phase repeatability. It achieves attenuation as low as 0.167 dB/m @ 1 GHz and 0.753 dB/m @ 18 GHz, with amplitude variation ≤ ±0.1 dB @ 18 GHz and phase deviation ≤ ±2° @ 10 GHz / ±3° @ 18 GHz. Phase drift remains below 750 PPM across –55 °C to +85 °C, guaranteeing high measurement consistency in varying environments. The cable supports up to 5.1 kW @ 1 GHz and 1.1 kW @ 18 GHz, delivering exceptional power capacity with minimal signal degradation.

Robust PUR Jacket and Dual Silver-Plated Shielding

Encased in a 9.15 mm PUR jacket, the CFS920MS cable offers superior mechanical protection, abrasion resistance, and chemical stability. Its dual silver-plated copper shielding provides > 90 dB EMI isolation, ensuring excellent noise suppression and clean signal transmission even in dynamic test setups. The flexible construction allows a 45.8 mm single-bend radius and 91.5 mm repeated-bend radius, making it ideal for movable or frequently adjusted precision measurement systems. With a weight of 142 g/m and 2000 VDC voltage withstand, it delivers a robust yet flexible design for high-demand RF testing.

Applications Requiring Flexibility and Repeatable Precision

The CFS920MS ultra-low-loss coaxial cable is ideal for vector network analyzers (VNAs), 5 G component validation, radar calibration, and microwave test systems where frequent movement and reliable electrical performance are required. Its stranded conductor design provides mechanical flexibility unmatched by solid-core cables, ensuring both ease of use and phase stability.
