Radio frequency (RF) circuit board topology

A multilayer printed circuit board for use in a radio frequency communication system, said multilayer printed circuit board comprising:

• a first conductive layer having a first conductive trace formed thereon terminating at a first via pad;
• a second conductive layer having a second conductive trace formed thereon terminating at a second via pad;
• an interconnection structure comprising:
• a signal conductor via connected at a first end to said first conductive trace by said first via pad and connected at a second end to said second conductive trace by said second via pad, wherein said signal conductor via propagates electrical signals between said first conductive trace on said first conductive layer and said second conductive trace on said second conductive layer;
• and
• a plurality of ground vias surrounding said signal conductor via, said plurality of ground vias having a position relative to said signal conductor via based upon a desired overall impedance of the interconnection structure,
• wherein said signal conductor via and plurality of ground vias extend beyond said second conductive layer, and
• wherein said multilayer printed circuit board further comprises a matching stub located on said second conductive layer, said matching stub comprising a prescribed length of conductive transmission line connected at a first end to said second via pad and connected at a second end to at least one of said plurality of ground vias.
