Impedance Discontinuity and Signal Reflection in PCB Transmission Lines

We previously quickly discussed signal reflection in our PCB Transmission Line series. This is an in-depth article about this very important topic that PCB designers should master. The first thing to remember is that reflections in transmission lines occur due to impedance discontinuity.

Impedance Calculator Tutorial

Sierra Circuits’ free Impedance Calculator will help PCB designers calculate their trace widths, single-ended or differential impedances – for both microstrip and stripline models – and other parameters such as the dielectric height, the dielectric constant, and the trace thickness. The tool will also provide a guide for dielectric constant values for various PCB materials.
