Phase-Stable 67GHz Rugged Precision Test Coaxial Cable with FEP Jacket – Model CFT260S

Phase-Stable, Low-Loss Precision Cable for 67 GHz RF and Microwave Testing

The CFT260S low-loss, phase-stable precision test coaxial cable is engineered for demanding RF and microwave measurements up to 67 GHz . Its advanced LD-PTFE dielectric, multi-layer shielding system, and ruggedized construction deliver excellent amplitude stability, strong isolation, and repeatable electrical performance under motion and thermal variation. Designed for metrology-grade testing, calibration labs, and high-frequency device validation, the CFT260S offers the electrical consistency and durability required for modern microwave characterization environments.

Stable Electrical Performance at High Frequencies

The CFT260S coaxial cable maintains a precise 50 Ω ±1.1 Ω impedance with ≤±3° phase stability at 18 GHz and ≤±5° at 26.5 GHz . Its amplitude stability remains within ±0.1 dB, while temperature-driven phase drift stays below 950 PPM from −55 °C to +85 °C, supporting long-duration measurement repeatability. With low attenuation down to 5.873 dB/m at 67 GHz, the CFT260S is optimized for VNA sweeps, high-frequency module testing, and precision-sensitive RF setups that demand consistent phase and amplitude control.

Rugged FEP Jacket and Multi-Layer Shielding Design

Encased in a robust 2.55 mm FEP jacket, the CFT260S offers excellent environmental resistance, long bending life, and chemical durability suitable for continuous laboratory operation . Its multilayer mechanical structure—featuring silver-plated copper ribbon, AL-Mylar lining, PI film reinforcement, and braided silver-plated copper shielding—achieves >90 dB shielding effectiveness. The cable remains electrically stable during motion, supported by a 13 mm single bend radius and 28 mm repeated bend radius, making it ideal for dynamic test fixtures and automated measurement systems.

Applications Requiring High Stability and Rugged Performance

The CFT260S phase-stable coaxial cable is designed for 67 GHz vector network analysis, mmWave module validation, phased-array development, radar subsystem evaluation, and precision RF calibration environments demanding ultra-stable electrical behavior. Its combination of low loss, strong shielding, and rugged flexibility makes it suitable for both R&D and high-repetition production test environments.

Manufactured by Mechanc Shanghai Information Technology, the CFT260S precision test coaxial cable provides the reliability, stability, and durability required for advanced RF and mmWave measurement applications up to 67 GHz. REACH & RoHS compliant.
