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.
Every day, PCB designs and components become smaller, faster – in other words, more complicated. It is now crucial to slow certain circuits down in order to allow specific functions of components to perform before others. The time of simple interconnecting traces and conductors is over.
