5G 基础设施升级项目

## Background 5G operates at higher frequencies, where the "skin effect" is pronounced. Current flows only in the outermost microns of the conductor. ## The Challenge Minimize attenuation in coaxial cables and connectors without the exorbitant cost of solid silver. ## The Solution Raytron Silver Clad Copper (SCC). - **Surface**: High-purity silver layer carries the majority of the high-frequency current. - **Core**: Copper provides bulk conductivity and mechanical support. - **Comparison**: Outperforms silver-plated copper due to thicker, more uniform silver layer and smoother interface. ## Results - **Performance**: -0.5dB attenuation improvement per meter at 28 GHz. - **Cost**: 80% cheaper than solid silver wire. - **Durability**: Silver cladding does not flake off during bending/connectorization like plating can.
