Abstract:
An interconnection circuit and related techniques are described. The interconnection circuit (10) includes a plated through hole (26) having a plurality of electrically isolated segments (26a, 26b) with at least one of the plurality of electrically isolated segments (26a) coupled to a signal path (27a, 27b) and at least one of the electrically isolated segments (26b) coupled to the ground (12). With this arrangement, the circuit provides a signal path between a first and a second different layers of a multilayer. By providing one segment (26a) as a signal segment and another segment (26b) as a ground segment the size and shape of the electrically isolated segments (26a, 26b) can be selected to provide the interconnection circuit having a predetermined impedance characteristic. The interconnection circuit can thus be impedance matched to circuit board circuits, devices and transmission lines, such as striplines, microstrips and co-planar waveguides. This results in an interconnection circuit which maintains the integrity of relatively high-frequency signals propagating through the interconnection circuit from the first layer to the second layer. The interconnect circuits can be formed by creating distinct conductor paths (26a, 26b) within the cylindrical plated through-holes (26) using variety of manufacturing techniques including, but not limited to, broaching techniques, electrostatic discharge milling (EDM) techniques and laser etching techniques.

Abstract:
A pedestal connector that incorporates one or more grouped element channel link transmission lines is seen to have a dielectric body and two opposing contact ends that are intended to contact opposing contacts or traces. The dielectric body has an S-shaped configuration such that the transmission lines supported thereon make at least one change in direction, thereby permitting the use of such connector to interconnect elements lying in two different planes. The transmission lines include slots that extend within the frame and which define opposing, conductive surfaces formed on the dielectric body which are separated by an intervening air gap.

Termination assemblies for terminating high-frequency data signal transmission lines include housings with one or more cavities that receive ends of the transmission line therein. The transmission line typically includes a dielectric body and a plurality of conductive elements disposed thereon, with the plurality of conductive elements being arranged in pairs for differential signal transmission. The termination assemblies, in one embodiment include hollow end caps that are formed from a dielectric and which have one or more conductive contacts or plated surfaces disposed on or within the cavity so that they will frictionally mate with the conductive traces on the transmission line. In another embodiment, a connector housing is provided with a center slot and a plurality of dual loop contacts to provide redundant circuit paths and low inductance to the termination assembly. A coupling element may be utilized in the slot to achieve a desired level of coupling between the termination contacts.
