High speed electrical connector

An electrical connector, comprising:

• a housing comprising a base portion, first and second walls extending from the base portion and separated by a slot;
• a plurality of conductive elements coupled to the first wall, the plurality of conductive elements comprising mating ends curving into the slot, and mounting ends opposite the mating ends;
• a first shielding member comprising a first portion disposed in the base portion, a second portion disposed in the first wall, and a third portion extending out of the base portion;
• and
• a second shielding member attached to the second wall, the second shielding member comprising a plurality of beams extending into the slot.

A connector subassembly, comprising:

• a plurality of conductive elements aligned in a row direction;
• an insulative member molded over the plurality of conductive elements, the insulative member comprising a plurality of windows exposing a subset of the plurality of conductive elements;
• and
• a shielding member comprising a plurality of windows aligning with the plurality of windows of the insulative member;
• and
• a lossy member molded over the shielding member, the lossy member comprising a plurality of windows aligning with the plurality of windows of the shielding member, and a plurality of projections through the shielding member, insulative member and selected ones of the plurality of conductive elements.
