Ultra Low Loss 26.5 GHz Precision Test Coaxial Cable with PFA Jacket – Model CFS480

High-Power, Low-Loss Coaxial Cable for Advanced RF Testing

The CFS480 ultra-low-loss precision test coaxial cable delivers outstanding electrical stability and mechanical reliability for precision measurement systems operating up to 26.5 GHz. Designed for engineers who demand repeatable accuracy in high-frequency environments, this 50 Ω cable ensures superior phase and amplitude consistency. Fully REACH and RoHS compliant, it aligns with Mechanc’s quality and environmental standards for laboratory and production-grade RF applications.

Stable Electrical Performance for Accurate Measurements

The CFS480 coaxial cable features a solid silver-plated copper inner conductor with an LD-PTFE dielectric, delivering exceptionally low attenuation of just 0.241 dB/m @ 1 GHz and 1.308 dB/m @ 26.5 GHz. Phase stability and amplitude stability remain excellent, ensuring dependable precision in VNA calibration, antenna characterization, and microwave component testing. Temperature-related phase variation is tightly controlled, guaranteeing repeatability even in fluctuating conditions.

Mechanical Strength and Shielding Integrity

Encased in a 4.80 mm FEP jacket, the CFS480 cable provides superior flexibility and thermal resistance up to +165 °C. Dual silver-plated copper shielding ensures > 90 dB shielding effectiveness and prevents external interference for consistent, low-noise measurements. With an 83 % velocity of propagation, 58 g/m weight, and 24 mm single-bend radius, it offers the ideal balance of ruggedness and handling ease for precision setups. The cable withstands up to 1500 VDC, supporting both laboratory and field-testing environments where mechanical reliability is critical.
