Features & Applications
It meets the technical requirements of precision microwave phase-stable RF coaxial cables. It features excellent electrical and mechanical performance, high shielding effectiveness, low attenuation, low VSWR, stable phase under bending and low temperature-induced phase drift. Widely used for RF and microwave signal transmission in phased-array radars, microwave modules, VNA test jumpers, military navigation and avionics equipment.
Operating Temperature: PTFE Dielectric: -55℃ ~ +200℃; FEP Jacket: -55℃ ~ +150℃

Notes
- All parameters listed are typical reference values at room temperature. The final acceptance is subject to the factory VNA test report.
- All cables adopt solid PTFE dielectric and full silver-plated copper conductors (no copper-clad steel). Double composite shielding: helically wrapped silver-plated copper tape plus silver-plated copper braid.
- SS402: Inner conductor Φ0.93mm, solid PTFE dielectric Φ2.98mm, finished outer diameter Φ4.10mm.
- Custom lengths are available. Cable assemblies with SMA / 2.92mm / 2.4mm high-frequency connectors can be fabricated. RoHS compliant.
