  • Electrical connector having a circuit board with controlled impedance
    Patent number: 7244126
    Abstract: An electrical connector comprises a housing holding a circuit board. The circuit board has a top surface which includes a first region and a second region. Circuit traces are formed on the top surface and extend in the first and second regions. A first ground plane is disposed at a first depth in the circuit board below the circuit traces in the first region. The first depth is selected to provide a specific characteristic impedance of the circuit traces in the first region. A second ground plane is disposed at a second depth in the circuit board below the circuit traces in the second region. The second depth is selected to provide a specific characteristic impedance of the circuit traces in the second region.
