Ultra Low Loss 50 GHz Precision Test Coaxial Cable with PFA Jacket – Model CFS310

Ultra-Low-Loss Precision Cable for Consistent RF and Microwave Testing

The CFS310 ultra-low-loss precision test coaxial cable is designed for engineers requiring consistent electrical performance and high phase stability in precision measurement systems. Operating up to 40 GHz with a 50 Ω impedance, it provides exceptional repeatability and signal integrity for vector network analyzer (VNA) calibration, radar evaluation, and advanced RF verification setups. Fully REACH and RoHS compliant, it upholds Mechanc’s high standards of quality, precision, and sustainability in professional RF laboratories.

Reliable Electrical Performance and Phase Stability

The CFS310 coaxial cable integrates a solid silver-plated copper inner conductor and LD-PTFE dielectric to ensure precise impedance control and minimal insertion loss. Attenuation remains extremely low—only 0.620 dB/m @ 1 GHz and 3.45 dB/m @ 26.5 GHz—while maintaining phase deviation within ±2° @ 10 GHz and ±3° @ 18 GHz. Amplitude variation stays ≤ ±0.1 dB @ 18 GHz, and thermal phase drift remains below 750 PPM between –55 °C and +85 °C, guaranteeing stable, repeatable results in temperature-sensitive environments.

Durable PFA Jacket and Shielding Integrity

Encased in a 3.10 mm PFA jacket, the CFS310 cable provides excellent resistance to heat, abrasion, and chemicals while retaining mechanical flexibility for frequent repositioning during test operations. Dual silver-plated copper shields achieve > 90 dB EMI suppression, preventing signal degradation from external interference and maintaining clean transmission even in high-density test environments. Its precisely engineered geometry preserves stable impedance and phase performance under mechanical stress or bending.

Applications Requiring Low Loss and Repeatable Accuracy

The CFS310 ultra-low-loss coaxial cable is ideal for laboratory-grade VNA calibration, satellite communication system validation, and high-frequency signal verification. Its solid-core structure and robust shielding ensure consistent performance and long-term measurement accuracy in both research and production testing.
