Ultra Low Loss 18 GHz Precision Test Coaxial Cable with PFA Jacket – Model CFS830

High-Power, Ultra-Low-Loss Coaxial Cable for Precision RF Testing

The CFS830 ultra-low-loss precision test coaxial cable is designed for high-power, low-attenuation RF applications that demand exceptional phase and amplitude stability. Operating up to 18 GHz with a 50 Ω impedance, it ensures highly accurate signal transmission and long-term reliability for calibration systems, radar testing, and microwave laboratory use. Fully REACH and RoHS compliant, it meets the highest standards for quality and environmental performance.

Superior Electrical Performance and Power Handling

The CFS830 coaxial cable features a solid silver-plated copper inner conductor (2.44 mm) and an LD-PTFE dielectric that deliver exceptional signal uniformity and minimal insertion loss. Attenuation remains extremely low—only 0.133 dB/m @ 1 GHz and 0.606 dB/m @ 18 GHz—while average power handling reaches 1.9 kW @ 1 GHz and 0.41 kW @ 18 GHz. Phase stability is maintained within ±2° @ 10 GHz and ±3° @ 18 GHz, and thermal phase drift remains below 750 PPM from –55 °C to +85 °C, ensuring stable, repeatable test results across wide temperature ranges.

Durable Mechanical Construction and Shielding Integrity

Encased in a 8.30 mm PFA jacket, the CFS830 cable provides superior mechanical protection, flexibility, and heat resistance up to +165 °C. Dual silver-plated copper shielding achieves > 90 dB EMI suppression, ensuring clear, distortion-free signal transmission even in high-interference environments. With a single-bend radius of 41 mm, a repeated-bend radius of 83 mm, and a weight of 162 g/m, it offers excellent durability and consistent impedance performance for long-term laboratory and production use. The cable withstands 2500 VDC for robust electrical insulation in demanding setups.

Applications Requiring Low Loss and High Stability

The CFS830 ultra-low-loss coaxial cable is ideal for vector network analyzer (VNA) calibration, high-power RF system testing, satellite communication evaluation, and other precision measurement systems where minimal loss and stable phase are critical. It combines mechanical strength, wide temperature tolerance, and consistent attenuation for engineers seeking dependable metrology-grade results.
