An apparatus is disclosed that substantially reduces or eliminates the resonance
that occurs in vias that connect the layers of a printed circuit board by electrically
coupling a first transmission line in a circuit board to a second transmission
line in a circuit board by two electrical paths having substantially the same electrical
length. The two electrical paths are created by connecting the first transmission
line to a first via which is in turn connected to a second via having a second
transmission line with a plurality of connecting electrical paths between the two
vias. In one illustrative embodiment, electrical traces are used to connect the
top of the first via to the top of the second via and the bottom of the first via
to the bottom of the second via.
