Abstract:
1. A transmission circuit comprising: a transmission line electrically coupling a first conductive via and a second conductive via, the first conductive via having a first via stub, wherein the transmission line configured to transmit a signal is coupled to the first conductive via towards a first end of the transmission line, and wherein the first via stub extends beyond the transmission line, the second conductive via having a second via stub, wherein the transmission line configured to transmit a signal is coupled to the second conductive via towards a second end of the transmission line, and wherein the second via stub extends beyond the transmission line; a transmitter chip electrically coupled towards a first end of the first conductive via, the transmitter chip having at least one transmitter lane; a connector electrically coupled towards a first end of the second conductive via; and a transmission line stub electrically coupled towards a second end of one of the first and second via stubs, wherein a combined length of the transmission line stub and the one of the first and second via stubs is configured to suppress a preselected frequency, wherein the first and second via stubs are unterminated via stubs.
