Polar's interconnected tools for impedance controlled PCBs are designed for OEMs and fabricators who are concerned with PCBs running in the popular 100MHz to ...

The Si8000m is a boundary element method field solver that builds on the familiar easy to use user interface in earlier Polar impedance design systems.

With PCBWay impedance calculator, you can calculate the approximate impedance of your PCB / high frequency circuit board. The surface finish is neglected.

An online calculator to add, subtract, multiply and divide polar impedances is presented.

JLCPCB's Free Impedance Calculator for impedance controlled PCBs, helps you calculate the track width value and recommended PCB stack-ups from target impedance.

Enter impedances Z as a complex number of the form a+jb and press "calculate". The output is the impedance in polar form with phase in degress and radians.

Speedstack PCB stackup design tool is a packaged combination of the Si8000m field solving impedance calculator and the Speedstack professional layer PCB stackup

With the Multi-CB impedance calculator, you can calculate the approximate impedance dimensioning of your PCB / high frequency circuit board.

The Impedance Calculator evaluates single-ended and differential impedance, signal losses, and crosstalk for various impedance models.

The Si8000m is a boundary element method field solver that builds on the familiar easy to use user interface in earlier Polar impedance design systems.
