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 deviation remains within ±2° @ 10 GHz and ±3° @ 18 GHz, while amplitude stability stays below ±0.1 dB @ 18 GHz, ensuring dependable precision in VNA calibration, antenna characterization, and microwave component testing. Temperature-related phase variation is tightly controlled below 750 PPM across –55 °C to +85 °C, guaranteeing repeatability even in fluctuating conditions.

Mechanical Strength and Shielding Integrity

Encased in a 4.80 mm PFA 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.

Available Variant for Enhanced Performance

For applications requiring even higher phase precision and improved durability, Mechanc offers an upgraded version of this model: the CFS480U ultra-low-loss precision test coaxial cable. It maintains the same 50 Ω impedance and frequency range while offering enhanced mechanical flexibility and wideband phase stability for high-end RF and microwave calibration systems.

Precision Applications Requiring Long-Term Phase Stability

The CFS480 ultra-low-loss coaxial cable is purpose-built for high-frequency testing, metrology-grade calibration, and microwave system integration. Its low attenuation, wide temperature range, and mechanical endurance make it suitable for 5 G, radar, and aerospace validation systems requiring precise phase control over time.
