40 GHz Phase-Stable Precision Test RF Coaxial Cable – CFT380

Phase-Stable 40 GHz Precision Test Cable for Measurement Confidence

Engineers developing laboratory metrology can use CFT380 as a phase-stable precision test RF coaxial cable with operation to 40 GHz. In the CFT380 implementation at 3.90 mm, the cft design focus is phase-conscious measurement work, making controlled routing especially important after calibration or reference-plane setup. Its individual values distinguish the CFT380 coaxial cable within the Phase-Stable CFT Precision Test Cables range.

Performance Inputs for Test-System Design — CFT380

At 40 GHz, its listed attenuation is 2.205 dB/m; the corresponding power figure is 0.074 kW. The CFT380 core uses a 1.02 mm silver plated copper inner conductor works with a 81% velocity of propagation. Delay modelling for CFT380 can start from its documented 81% velocity-of-propagation figure.

Calibration Work That Depends on Phase Discipline — CFT380

Taken together, these figures position CFT380 for high-frequency validation and phase comparison measurements, subject to the final assembly length and connector choice. Broader geometry and performance choices are listed under Precision Test Coaxial Cables when comparing alternatives to CFT380.

Mechanical Repeatability After Calibration — CFT380

Installation geometry is set by the 3.90 mm diameter and 19.00 mm static radius and 38.00 mm dynamic bend radius; allowable temperature spans -55 to +165 °C. On CFT380, the FEP outer construction should be considered alongside the 3.90 mm envelope during material and routing reviews. Its 3.90 mm profile gives the CFT380 RF cable a middle-ground geometry between miniature routing and larger power-oriented cables.

As a distinct Mechanc cable configuration, CFT380 brings measurable criteria to frequency, loss, power and routing decisions. The Mechanc Shanghai Information Technology Co., Ltd. portfolio provides the wider context for CFT380 and its intended RF role.
