Shieldless, high-speed electrical connectors

An electrical connector, comprising:

• a dielectric base that defines a mate surface and a mount surface;
• a first linear array of electrical blade contacts each having a free-ended mating portion that extends from the mate surface of the dielectric base, the first linear array comprising a first signal contact, a second signal contact positioned adjacent to the first signal contact and forming a differential signal pair therewith, and a ground contact positioned adjacent to the second signal contact,
• wherein the first signal contact, the second signal contact, and the ground contact are each elongated in a first direction along the first linear array.
