Ultra Low Loss 40 GHz Precision Test Coaxial Cable with PFA Jacket – Model CFS220

Ultra-Low-Loss Precision Cable for High-Frequency RF Testing

The CFS220 ultra-low-loss precision test coaxial cable delivers exceptional phase stability and low attenuation for advanced RF and microwave measurement systems. Operating up to 40 GHz with a 50 Ω impedance, it ensures high repeatability and electrical accuracy in demanding test environments such as vector network analyzer (VNA) calibration, radar system evaluation, and 5G component verification. Fully REACH and RoHS compliant, it meets international standards for quality and sustainability in professional laboratories.

Stable Electrical Characteristics and Low Attenuation

The CFS220 coaxial cable integrates a solid silver-plated copper inner conductor and LD-PTFE dielectric that provide uniform impedance and ultra-low loss across the frequency spectrum. Typical attenuation is just 0.637 dB/m @ 1 GHz and 3.12 dB/m @ 26.5 GHz, while phase deviation remains within ±2° @ 10 GHz and ±3° @ 18 GHz. Thermal phase drift stays below 750 PPM between –55 °C and +85 °C, ensuring consistent and repeatable performance under varying temperature conditions.

Robust PFA Jacket and High Shielding Effectiveness

Encased in a 2.20 mm PFA jacket, the CFS220 cable offers superior protection against abrasion, heat, and chemical exposure while maintaining flexibility for dynamic test setups. Dual silver-plated copper shielding achieves > 90 dB EMI suppression, preserving clean signal transmission even in environments with strong electromagnetic interference. The mechanical structure ensures stable impedance performance during bending and handling, supporting long-term durability in daily test operations.

Available Variants for Extended Frequency Applications

The CFS220 Series includes enhanced configurations for broader test requirements:

• CFS220 — the standard version providing dependable low-loss performance up to 40 GHz.
• CFS220U — the extended-frequency model supporting precision measurements up to 67 GHz with improved wideband phase control.

These variants allow RF engineers to choose between optimal flexibility and extended frequency capability while maintaining the same high level of Mechanc quality and consistency.

Applications Requiring Precision and Stability

The CFS220 ultra-low-loss coaxial cable is ideal for metrology, broadband RF testing, and VNA calibration systems requiring stable phase and minimal signal loss. Its balanced electrical and mechanical characteristics make it equally suitable for laboratory and production environments.
