Abstract
High-speed data connectors having a variety of different implementations to address unwanted electromagnetic radiation and interference are described. In some instances, resonant unit structures are added within the existing connector cavity that absorb and dampen unwanted electromagnetic radiation. In other instances, resonant unit structures are added to the exterior of the connector to reduce and eliminate surface currents that can occur on the solid metal shield of the connector. In these and other instances, the resonant unit structure can be formed from a stacked structure having a resonant structure arranged in close proximity to some of the connector pins to absorb unwanted radiation from those pins. The absorbed energy is transferred to ground through other components in the stack. In still other instances, various different materials are provided to replace the conventional plastic material that is used to keep the connector pins in place and in alignment. The different materials can absorb unwanted electromagnetic radiation, and can be selected to address particular frequency ranges.
