40 GHz 034 Standard Semi-Rigid RF Coaxial Cable G08E
P/N: G08E
- For high-density RF module routing
- 0.864 mm OD supports compact wiring
- Seamless copper tube provides high shielding
- Solid PTFE for cost-effective signal paths
- Rated to 40 GHz for module links
Engineering Note
The G08E is a 40 GHz micro standard semi-rigid coaxial cable designed for high-density internal RF routing where cable diameter, shielding, and form-stable geometry 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 module interconnects, precision instrument signal paths, and compact high-frequency test platforms. The 0.864 mm OD construction provides a compact routing option while offering lower attenuation than the smaller G06E cable.
