Phase-Stable 40GHz Ultra Flexible Precision Test Coaxial Cable with FEP Jacket – Model CFT420MWA70

Phase-Stable, Ultra-Flexible Precision Cable with Armor for 40 GHz RF Testing

The CFT420MWA70 ultra-flexible, low-loss precision test coaxial cable is designed for high-performance RF and microwave measurements up to 40 GHz . Built on the proven CFT420 architecture and reinforced with a multi-layer armored structure and bicolor PTFE woven jacket, this model provides exceptional mechanical durability, long bending life, and stable electrical behavior under motion. Engineered for demanding laboratory and production environments, the CFT420MWA70 delivers consistent amplitude and phase performance suitable for metrology-grade measurement systems and dynamic test setups.

Stable Electrical Performance for Precision Measurements

The CFT420MWA70 coaxial cable maintains a precise 50 Ω ±1.1 Ω impedance and provides ≤±3° phase stability at 18 GHz and ≤±5° at 26.5 GHz . Its amplitude variation is held within ±0.05 dB at 40 GHz, ensuring extremely stable measurements during VNA sweeps and calibration procedures. Temperature-induced phase drift remains below 750 PPM across −55 °C to +165 °C, enabling excellent long-duration repeatability. Low attenuation—2.641 dB/m at 40 GHz—supports accurate S-parameter characterization and high-frequency signal verification.

Armored, Ultra-Flexible Construction and High Shielding Integrity

Encased in a durable 4.20 mm FEP jacket and protected by a 6.40 mm multi-material armor layer finished with a 7.00 mm bicolor PTFE woven jacket, the CFT420MWA70 offers outstanding abrasion resistance, crush protection, and environmental durability suited for harsh or high-motion test environments . Its multi-layer mechanical structure—including LD-PTFE dielectric, PTFE reinforcement, and dual silver-plated copper shielding—achieves >90 dB shielding effectiveness, preserving measurement integrity. The cable maintains stable performance under frequent repositioning thanks to a 40 mm single-bend radius, 70 mm repeated-bend radius, and a proven 100,000-cycle bending life.

Applications Requiring Rugged, Phase-Stable Flexibility

The CFT420MWA70 phase-stable coaxial cable is ideal for flexible 40 GHz VNA testing, RF calibration, radar and communication module characterization, automated test systems, and environments where both electrical precision and mechanical durability are critical.
