A connector assembly is provided that is suitable for modifying the resonant frequency of ground terminals used in conjunction with high data rate signal terminals. Ground terminals may be interconnected with a conductive bridge so as to provide ground terminals with a predetermined maximum effective electrical length. Reducing the effective electrical length of the ground terminal can move the resonance frequencies of the connector outside the operational range of frequencies at which signals will be transmitted.
