A leadframe module for an electrical connector includes a leadframe having contacts initially held together as part of the leadframe. The contacts have mating ends configured to be mated to corresponding mating contacts. The contacts having mounting ends configured to be terminated to corresponding conductors. Dielectric shells coat corresponding contacts. Outer shields are applied to corresponding dielectric shells. Each of the contacts, dielectric shells and outer shields define corresponding shielded transmission lines of the leadframe module. Optionally, a ground plate may be coupled to each of the transmission lines and electrically connected to the outer shields of the transmission lines to electrically common each of the outer shields.
