What is a PCB Transmission Line?

Originally published at: https://www.protoexpress.com/blog/pcb-transmission-line/

A PCB transmission line is a type of interconnection used for moving signals from their transmitters to their receivers on a printed circuit board. A PCB transmission line is composed of two conductors: a signal trace and a return path which is usually a ground plane. The volume between the two conductors is made up of the PCB dielectric material.
