Phase-Stable 18GHz Low-Loss RF Coaxial Cable – Model CFA570MW

Flexible Low-Loss RF Cable with Stranded Core Design

The CFA570MW phase-stable low-loss coaxial cable is developed for RF and microwave systems that demand both electrical accuracy and mechanical flexibility. Operating up to 18 GHz with 50 Ω impedance, it maintains excellent phase and amplitude stability even after repeated bending cycles, ensuring reliable signal transmission in dynamic testing and routing applications. Explore the complete CFA Series – Phase-Stable Low-Loss Coaxial Cables for other models and diameters.

Stranded Inner Conductor for Enhanced Flexibility

The CFA570MW cable incorporates a 1.43 mm stranded silver-plated copper inner conductor that provides superior flexibility and resistance to mechanical fatigue compared to solid-core designs. The low-density PTFE dielectric and dual silver-plated copper shielding layers ensure consistent impedance, while the FEP jacket offers strong chemical and thermal resistance up to +165 °C. Attenuation remains as low as 1.23 dB/m @ 18 GHz with amplitude stability within ±0.1 dB and phase stability within ±5°.

Ideal for Dynamic or Repetitive Motion Environments

Engineered for long bending life, the CFA570MW phase-stable cable supports tight routing in portable or automated test setups, maintaining low loss and repeatable phase response over time. For setups requiring maximum thermal and mechanical rigidity, consider the CFA520 Phase-Stable Low-Loss Coaxial Cable, which uses a solid inner conductor for enhanced stability under fixed installation.

Stable Performance for Reliable RF Transmission

With ≥ 90 dB shielding effectiveness, a 29 mm single-bend radius, and a 58 mm repeated-bend radius, the CFA570MW low-loss coaxial cable is suited for broadband analyzers, radar systems, and phase-critical assemblies. For additional cable options, visit the Low-Loss Coaxial Cable Series.

Manufactured by Mechanc Shanghai Information Technology Co., Ltd., the CFA570MW phase-stable low-loss coaxial cable combines stranded-core flexibility, excellent phase accuracy, and verified REACH and RoHS compliance for stable RF performance in motion-intensive environments.
