Phase-Stable 67GHz Rugged Precision Test Coaxial Cable with FEP Jacket – Model CFT240A47

Armored Low-Loss & Phase-Stable Cable for Extended RF Testing Reliability

The CFT240A47 low-loss & phase-stable precision test coaxial cable represents the armored evolution of the CFT240, combining superior electrical consistency with outstanding mechanical endurance. Designed for high-frequency laboratories and automated test setups, it operates up to 67 GHz while maintaining amplitude stability within ±0.05 dB and phase deviation ≤ ±7° @ 67 GHz. With its reinforced structure and bi-color PTFE woven armor jacket, the CFT240A47 offers long bending life, stable impedance, and repeatable measurement accuracy under continuous motion. See the full CFT Series – Low-Loss & Phase-Stable Precision Test Cables for additional models.

Superior Electrical Stability and Reinforced Construction

The CFT240A47 coaxial cable integrates the same precision silver-plated copper inner conductor (0.50 mm) and LD-PTFE dielectric (1.38 mm) as the base model, but adds a multi-layer composite armor (4.20 mm) and PTFE woven jacket (4.70 mm) to ensure mechanical protection and dimensional stability during flexure. The velocity of propagation remains high at 81 %, while its 500 V DC voltage rating guarantees safe performance in critical RF test conditions. For compact test stations prioritizing lightweight flexibility, the original CFT240 – Low-Loss & Phase-Stable Precision Test Coaxial Cable provides identical electrical performance without the additional armored layers.

High Shielding Effectiveness and Long-Term Durability

With dual silver-plated copper shielding exceeding > 90 dB EMI suppression, the CFT240A47 test cable ensures clean signal integrity even in high-density test environments. Its armored body enables a single-bend radius of 30 mm and a repeated-bend radius of 50 mm, supporting up to 100,000 flex cycles without electrical degradation. The rugged exterior offers excellent abrasion and chemical resistance, ideal for continuous movement in production or calibration systems.

High-Frequency Applications and Long Bending Life

The CFT240A47 armored coaxial cable is optimized for automated VNA calibration, radar component testing, and precision RF measurement where both amplitude and phase consistency are critical. With attenuation as low as 0.637 dB/m @ 1 GHz and stable operation up to 67 GHz, it offers exceptional repeatability across extended mechanical use. The durable multi-layer armor system protects against mechanical stress, vibration, and frequent connector re-mating.
