Abstract: A conductive sleeve includes a central portion with a front, a rear, and sides; at least one flange mated with at the sides of the central portion; and capacitive section that extends from a portion of the central portion at the rear of the central portion. The central portion is adapted to be placed over an end of a cable and extend over at least one conductor of the cable. The at least one flange is adapted to connect with a mating conductor. The capacitive section has a width smaller than a width of the central portion and is adapted to be placed immediately adjacent to an insulator of the cable and another conductor of the cable to form substantially a capacitive shorting circuit.

Abstract: An improved power connector provides improved signal integrity in an interconnection system. The connector includes a filter element between a supply contact and a return contact. The filter element may be primarily capacitive, but may also include a resistance and a ferrite member. For connectors that include multiple sets of supply and return contacts, a single filter element may be included, or multiple filter elements may be included between multiple pairs of power and return contacts. The filter element may be formed within a connector housing or otherwise incorporated when the connector is manufactured. Alternatively, the filter element may be inserted into a receptacle such that filtering may be selectively incorporated as the connectors are used. When connected to a conducting loop for carrying power supply, the filter element provides substantially zero attenuation at frequencies below about 50 MHz and in excess of 10 dB of attenuation over a range that extends above 500 MHz.

Abstract: A waferized connector connects to two twinax cables. The connector includes a molded lead frame, ground sleeve, twinax cable, and overmolded strain relief. The lead frame is molded to retain a lead frame containing both differential signal pins and ground pins. Termination sections are provided at the rear of the lead frame to terminate each of the signal wires of the cables to respective signal lands. The ground sleeve has two general H-shape structures connected together by a center cross-support member. Each of the H-shaped structures having curved legs, each of which fits over the signal wires of one of the twinax cables. The wings of the ground sleeve are terminated to the ground lands of the lead frame and the drain wire of the cable is terminated to the ground sleeve to terminate the drain wire to a ground reference. The ground sleeve controls the impedance in the termination area of the cables, where the twinax foil is removed to expose the wires for termination to the lands.

Abstract: An improved broadside coupled, open pin field connector. The connector incorporates lossy material to selectively dampen resonance within pairs of conductive members connected to ground when the connector is mounted to a printed circuit board. The material may also decrease crosstalk and mode conversion. The lossy material is selectively positioned to substantially dampen resonances along pairs that may be connected to ground without unacceptably attenuating signals carried by other pairs. The lossy material may be selectively positioned near mating contact portions of the conductive members. Multiple techniques are described for selectively positioning the lossy material, including molding, inserting lossy members into a housing or coating surfaces of the connector housing. The lossy material alternatively may be positioned between broad sides of conductive members of a pair.
