A modular electrical connector with broad-side coupled signal conductors in a right angle intermediate portion. Broadside coupling provides balanced pairs for very high frequency operation. The connector is assembled with multiple subassemblies, each of which has multiple pairs of signal conductors. The subassemblies are formed from an insulative portion having grooves in opposite sides into which the intermediate portions of signal conductors. Covers, holding the signal conductors in the grooves, establish the position of the signal conductors relative to reference conductors at the exterior of subassembly, so as to provide a controlled impedance. Lossy material is positioned between the pairs in a subassembly and/or contacts the reference conductors of the subassemblies, and the lossy material of the subassemblies is in turn connected with a conductive structure.

Each contact module has an insulator received in the cavity and a plurality of contacts insert-molded in the insulator, each contact defines a contacting arm and a soldering portion. The insulative housing defines a pair of locating portions extending downwards from two sides of the mounting portion, the distance between the pair of locating portions is smaller than an internal diameter of the cavity, a pair of demising slots are formed on an interior side of each locating portion for the contact modules passing through.

Examples of electrical connectors that incorporate electromagnetic interference (EMI) absorbing materials are described. In one example, an electrical connector includes a first pair of conductors, a second pair of conductors, and electromagnetic interference (EMI) absorbing material at least partially separating the first pair of conductors from the second pair of conductors. Each of the first and second pairs of conductors defines one of a differential pair or a signal conductor/ground pair. The EMI absorbing material may be configured to attenuate, primarily by absorption, an electromagnetic field generated due to transmission of electrical signals via one of the first pair and second pair of conductors to reduce the electromagnetic inference from the electromagnetic field on the other of the first pair and second pair of conductors.
