Abstract
Embodiments of the present invention provide for a transmission circuit that includes a transmission line and a conductive via. The transmission line is electrically coupled to a first conductive via and a second conductive via. The first conductive via includes a first via stub, wherein the transmission line is configured to transmit a signal that is coupled to the first conductive via, and wherein the first via stub extends beyond the transmission line. The second conductive via includes a second via stub, wherein the transmission line is configured to transmit a signal that is coupled to the second conductive via, and wherein the second via stub extends beyond the transmission line. A transmission line stub is electrically coupled to the transmission line or to at least one of the conductive vias, wherein the length of the transmission line stub is configured to suppress a preselected frequency.
