Ultra Low Loss 40 GHz Precision Test Coaxial Cable with PFA Jacket – Model CFS360

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

The CFS360 ultra-low-loss precision test coaxial cable is designed for engineers who demand superior phase stability and low attenuation in high-frequency measurement systems. Operating up to 40 GHz with a 50 Ω impedance, it delivers consistent electrical performance for vector network analyzer (VNA) calibration, radar validation, and 5G signal verification. Fully REACH and RoHS compliant, it ensures reliable performance and long-term durability in advanced RF and microwave testing environments.

Exceptional Electrical Performance and Phase Stability

The CFS360 coaxial cable features a solid silver-plated copper inner conductor and precision LD-PTFE dielectric that provide excellent impedance uniformity and minimal signal loss. Typical attenuation is just 0.670 dB/m @ 1 GHz and 3.62 dB/m @ 26.5 GHz, while phase deviation remains within ±2° @ 10 GHz and ±3° @ 18 GHz. With amplitude variation ≤ ±0.1 dB @ 18 GHz and phase drift below 750 PPM between –55 °C and +85 °C, the cable guarantees consistent performance even in temperature-variable test setups.

Durable Construction and Shielding Reliability

Encased in a 3.60 mm PFA jacket, the CFS360 cable combines mechanical flexibility with robust thermal and chemical resistance. Dual silver-plated copper shields provide > 90 dB EMI suppression, ensuring clean and stable signal transmission even in dense electronic environments. The cable’s balanced geometry maintains uniform impedance and phase consistency during repeated use, minimizing measurement uncertainty in precision test systems.

Applications Requiring Stability and Low Attenuation

The CFS360 ultra-low-loss coaxial cable is ideal for high-frequency VNA calibration, microwave testing, and satellite communication system validation, where consistent phase and amplitude response are critical. Its solid-core structure and precise shielding make it suitable for both laboratory and production applications.
