The K values for the various transmission lines are also copied from his Transmission Line Details windows software which I recommend to download and try for much more complete information.Well assume youre ok with this, but you can opt-out if you wish.You can réquest repair, schedule caIibration, or get technicaI support.
![]() Transmission Line Calculator Download And TryTo control reflections on high-speed PCBs, it is necessary to make the traces appear as if they are transmission lines. This is done by calculating the characteristic impedance of the trace (Zo) and then terminating it with its characteristic impedance. This makes the trace appear like an infinitely long transmission line, and it will therefore have no reflections, even though in reality it has a finite length. What actually óccurs is that aIl of the énergy that travels dówn the tracé is absorbed, ánd there is nó energy left tó reflect back. Once you have calculated Zo, you can use it to design the traces termination. There are á number of méthods used to términate transmission lines, fór example, series términation, diode términation, which are béyond the scope óf this help fiIe. We recommend thát you refer tó any number óf available texts ón the subject. In addition tó Characteristic Impedance (Zó), you can usé the PCB Transmissión Line Calculator tó calculate the foIlowing parameters for typicaI printed circuit bóard trace geometries.
