ABSTRACT:
An electrical connector includes a housing and a plurality of contacts within the housing that are configured to engage with mating contacts of a mating connector. The contacts form at least a first differential pair and a second differential pair. The electrical connector also includes a circuit board housed within the housing. The circuit board has a substrate body formed from a dielectric material and includes a first trace electrically coupled to a contact of the first differential pair and a second trace electrically coupled to a contact of the second differential pair. At least one of the first and second traces is an open-ended trace. The circuit board also has a non-ohmic plate that is positioned adjacent to the traces. The plate is positioned to electromagnetically couple the first and second traces to each other and the non-ohmic plate and traces are configured for a desired electrical performance.
