Abstract
A connector is provided that includes a plurality of wafers. Each wafer supports a terminal and adjacent signal wafers are configured so as to provide broad-side coupled terminals. A pair of signal terminals can be surrounded on both sides by ground wafers that offer shielding so as to help isolate one signal pair from another signal pair. The geometry of the wafers can be adjusted so as to provide a tuned transmission channel. The resultant tuned transmission channel can be configured to provide desirable performance at high signaling frequencies of 12-16 GHz or even higher signaling frequencies such as 20 GHz.
Claims11
A connector, comprising:
- a first wafer including a first terminal, the first terminal being a ground terminal;
- a second wafer positioned adjacent the first wafer, the second wafer including a first truss that supports a second terminal, the second terminal being a signal terminal;
- a third wafer positioned adjacent the second wafer, the third wafer including a second truss that supports a third terminal, the third terminal being a signal terminal and the second terminal and the third terminal being a differential pair of signal terminals;
- a fourth wafer positioned adjacent the third wafer, the fourth wafer including a fourth terminal, the fourth terminal being a ground terminal, wherein the first through fourth wafers are in series, and each truss is formed of insulative material and defines a dielectric constant for each of the terminals, wherein the dielectric constant associated with the coupling between the second and third terminals is different than the dielectric constant between the first wafer and second terminal and between the third terminal and the fourth wafer.
