Ultra Low Loss 13.5 GHz Precision Test Coaxial Cable with PFA Jacket – Model CFS1000

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

The CFS1000 ultra-low-loss precision test coaxial cable is designed for high-power RF testing environments that demand superior phase and amplitude stability. Operating up to 13.5 GHz with a 50 Ω impedance, it provides outstanding electrical consistency and mechanical durability for use in calibration systems, microwave benches, and radar validation setups. Fully REACH and RoHS compliant, this high-performance model ensures both precision and environmental responsibility for professional RF laboratories.

Exceptional Power Handling and Electrical Stability

The CFS1000 coaxial cable integrates a solid silver-plated copper inner conductor (3.00 mm) and LD-PTFE dielectric that deliver ultra-low insertion loss and excellent impedance uniformity. Attenuation remains minimal—only 0.120 dB/m @ 1 GHz and 0.498 dB/m @ 13.5 GHz—while supporting average power levels up to 6.9 kW @ 100 MHz and 2.1 kW @ 1 GHz. Phase stability is maintained within ±2° @ 10 GHz, with amplitude variation ≤ ±0.1 dB @ 13.5 GHz. The design ensures phase consistency of < 750 PPM between –55 °C and +85 °C for reliable test repeatability under varying thermal conditions.

Robust Mechanical Design and Shielding Performance

Encased in a 10.00 mm PFA jacket, the CFS1000 cable provides exceptional chemical resistance, heat tolerance, and protection against mechanical stress. Dual silver-plated copper shields achieve > 90 dB EMI suppression, guaranteeing stable, interference-free measurements. The cable withstands voltages up to 2900 VDC, with a single-bend radius of 40 mm and repeated-bend radius of 100 mm, ensuring both flexibility and longevity in dynamic test environments. With a weight of 200 g/m and an 83 % velocity of propagation, it provides both mechanical reliability and electrical precision in demanding laboratory conditions.

Applications Requiring High Power and Ultra-Stable Phase

The CFS1000 ultra-low-loss coaxial cable is ideal for vector network analyzers (VNAs), RF amplifier testing, high-power microwave systems, and antenna characterization setups where maximum power transfer and low insertion loss are critical. Its combination of strength, accuracy, and thermal stability ensures dependable performance in continuous testing or production environments.
