Abstract:
1. A printed circuit board (PCB) having first and second major surfaces comprising: at least one signal contact pad on the first major surface of the PCB; a signal lead extending across the first major surface of the PCB and connecting to the signal contact pad; at least three conducting ground planes extending through the PCB parallel to one another, a non-conducting gap in at least the ground plane closest to the first major surface of the PCB, said non-conducting gap being in line with the signal contact pad on the first major surface; at least one signal contact pad on the second major surface of the PCB; a signal lead extending across the second major surface of the PCB and connecting to the signal contact pad on the second major surface of the PCB; a non-conducting gap in at least the ground plane closest to the second major surface of the PCB, said non-conducting gap being in line with the signal contact pad on the second major surface; at least one conducting ground plane between the ground plane closest to the first major surface of the PCB and the ground plane closest to the second major surface of the PCB; and a ground connection that connects to all the ground planes and extends to the ground planes from one of the first and second major surfaces of the PCB but not the other major surface.
