Phase-Stable 26.5GHz Ultra Flexible Precision Test Coaxial Cable with FEP Jacket – Model CFT500MW

Phase-Stable, Ultra-Flexible Precision Cable for 26.5 GHz RF and Microwave Testing

The CFT500MW ultra-flexible, low-loss precision test coaxial cable is engineered for high-accuracy RF and microwave measurements up to 26.5 GHz . Built with a multi-fiber stranded silver-plated copper conductor, LD-PTFE dielectric, and reinforced multilayer shielding, it delivers excellent phase stability, low attenuation, and reliable performance under dynamic motion. Designed for precision VNA work, calibration routines, and motion-intensive test setups, the CFT500MW provides the electrical consistency required for metrology-grade RF environments.

Stable Electrical Performance for Precision Measurements

The CFT500MW coaxial cable maintains a precise 50 Ω ±1.1 Ω impedance and achieves ≤±3° phase stability at 18 GHz and ≤±5° at 26.5 GHz . Amplitude variation is held within ±0.1 dB, while temperature-driven phase drift remains below 750 PPM across −55 °C to +165 °C, ensuring long-term repeatability. With attenuation as low as 1.588 dB/m at 26.5 GHz and a velocity of propagation of 82%, the CFT500MW supports precise S-parameter characterization and high-frequency signal integrity in demanding RF setups.

Ultra-Flexible FEP Jacket and Multi-Layer Shielding Integrity

Protected by a durable 5.10 mm FEP jacket, the CFT500MW provides excellent thermal resistance, chemical durability, and repeated-bend endurance suitable for continuous laboratory use . Its mechanical structure—featuring FEP wrapping, LD-PTFE dielectric, PTFE reinforcement, and dual silver-plated copper shielding—achieves >90 dB shielding effectiveness, ensuring strong EMI immunity. A 25 mm single-bend radius and 50 mm repeated-bend radius allow stable electrical behavior during frequent repositioning typical of dynamic test fixtures and ATE systems.

Applications Requiring Ultra-Flexible, Phase-Stable Performance

The CFT500MW phase-stable coaxial cable is ideal for 26.5 GHz VNA measurements, RF calibration, radar and communication module testing, automated test systems, and any laboratory or production setting requiring high flexibility with uncompromised phase and amplitude stability. Part of Mechanc’s Low-Loss Phase-Stable Coaxial Cable Series, it delivers consistent performance for both R&D and metrology-grade environments.
