Impedance Calculation

With AlteraFlex impedance calculator, you can calculate the approximate impedance of your PCB / high frequency circuit board. The surface finish is neglected. We recommend the software from Polar Instruments if you want to get exact impedance calculation. Note: The results are only for approximation and rough estimation, the final values and the corresponding layer construction have to be calculated by us. The stackup information check here.

Instructions: Please select the value to be determined. You can then adjust the other parameters according to your needs.
