Abstract:
Embodiments of the present invention provide for a transmission line stub that includes a via stub of a conductive via. The conductive via includes a via stub and a coupling element, wherein a first transmission line configured to transmit a signal is coupled to the conductive via at the intersection of the via stub and the coupling element. The coupling element is configured to transmit the signal from the first transmission line. A line stub electrically coupled to the via stub, wherein the length of the line stub is selected such that the transmission line stub having a length of the sum of the lengths of the via stub and the line stub is configured to suppress a preselected frequency.
