Engineering Note
The G12E is a 40 GHz compact standard semi-rigid coaxial cable designed for RF module internal routing where shielding, controlled cable forming, and stable signal paths are key selection factors. Its construction uses a silver-plated copper inner conductor, solid PTFE dielectric, and seamless copper tube outer shield, supporting dense microwave component interconnects, precision instrument signal paths, and compact high-frequency test platforms. The 1.220 mm OD construction provides a practical balance between compact routing and lower attenuation than smaller standard semi-rigid cables.
