Apparatus for forming a connection between a circuit board and a connector, having a signal launch

A connection system, comprising:

• a circuit board that includes (i) a circuit board portion having a top surface, a bottom surface, a signal layer, a ground layer, and dielectric material that physically separates the signal layer and the ground layer, and (ii) a signal launch having:
• a signal via that physically contacts a signal conductor of the signal layer and the dielectric material of the circuit board portion, the signal via extending entirely through the circuit board portion from the top surface of the circuit board portion to the bottom surface of the circuit board portion, and
• a first set of ground vias and a second set of ground vias that physically contact a ground conductor of the ground layer and the dielectric material of the circuit board portion, wherein each of the first set of ground vias is disposed a first radial distance from the signal via, wherein each of the second set of ground vias is disposed a second radial distance from the signal via, and wherein the first and second radial distances are different;
• and
• a coaxial connector that mounts to the signal launch of the circuit board in order to provide electrical access to the signal and ground conductors of the circuit board portion.
