Phase-Stable 40GHz Ultra flexible Precision Test Coaxial Cable with FEP Jacket – Model CFT420MW

Phase-Stable, Ultra-Flexible Precision Cable for 40 GHz RF and Microwave Testing

The CFT420MW ultra-flexible, low-loss precision test coaxial cable is designed for high-performance RF and microwave measurements up to 40 GHz . Its multi-fiber stranded silver-plated copper conductor, advanced LD-PTFE dielectric, and reinforced multilayer shielding structure deliver exceptional amplitude and phase stability under motion. Engineered for durability, flexibility, and measurement repeatability, the CFT420MW is ideal for dynamic test environments, calibration laboratories, and sensitive VNA measurement tasks where cable motion must not degrade accuracy.

Stable Electrical Performance for Precision Measurements

The CFT420MW coaxial cable maintains a true 50 Ω ±1.1 Ω impedance and provides ≤±3° phase stability at 18 GHz and ≤±5° at 26.5 GHz . Amplitude stability remains within ±0.1 dB, and temperature-induced phase drift stays below 950 PPM across the −55 °C to +165 °C range, ensuring reliable long-term repeatability. With attenuation of 2.712 dB/m @ 40 GHz and a velocity of propagation of 81%, the CFT420MW supports precise S-parameter measurements and demanding calibration routines without compromising accuracy.

Ultra-Flexible FEP Jacket and Robust Shielding Integrity

Encased in a durable 4.20 mm FEP jacket, the CFT420MW delivers outstanding chemical resistance, thermal stability, and mechanical endurance suitable for continuous movement in laboratory use . Its rugged construction includes a multi-fiber stranded inner conductor, FEP wrapping, LD-PTFE dielectric, PTFE reinforcement layer, and dual silver-plated copper shielding, achieving >90 dB shielding effectiveness. With a 21 mm single-bend radius and 42 mm repeated-bend radius, the cable maintains consistent electrical behavior during frequent repositioning, making it ideal for ultra-flexible, motion-intensive test applications.

Applications Requiring Ultra-Flexible, Phase-Stable Performance

The CFT420MW phase-stable coaxial cable is optimized for 40 GHz vector network analysis, RF calibration, radar and communication module validation, dynamic test fixtures, and precision setups where motion-related instability must be minimized. Its combination of flexibility, durability, and low-loss performance makes it suitable for demanding R&D and production-level environments.

Manufactured by Mechanc Shanghai Information Technology, the CFT420MW precision test coaxial cable delivers rugged flexibility, stable electrical performance, and long-term reliability for high-frequency RF and microwave measurement applications up to 40 GHz. REACH & RoHS compliant.
