ABSTRACT:
The present invention provides a matched-impedance jumper that is operable to connect pairs of differential signal conductors to provide improved signal transmission characteristics. In an embodiment of the invention, the impedance-matched jumper is used to connect a first pair of differential signal conductors to a selected pair of differential signal conductors selected from a plurality of second pairs of differential signal conductors. The impedance-matched jumper comprises a plurality of input pins that are operable to connect with a plurality of connection pads on the first pair of differential signal conductors and a plurality of output pins operable to connect with a plurality of connection pads on the predetermined second pair of differential signal conductors. A plurality of internal conductors are operably connected to the input pins and the output pins to define a signal path therebetween. The signal path defined by the input pins, the output pins, and the internal conductors provides an impedance-matched passthrough for differential signals.
