Need asymmetric differential stripline impedance calculator

[Alan0354]

Hi
I have no luck finding an asymmetric differential stripline impedance calculator online. Anyone have suggestion of one?

Thanks
Alan

You know that Saturn PCB toolkit does the calculation? https://www.saturnpcb.com/pcb_toolkit.htm

Thanks FvM. I don't think they have asymmetric differential stripline though.

They do

Thanks FvM, I found it. I did not see it first.

Do you know of another one. I want to run two to verify each other. I had two different calculator that gave me different answers, it's over 20% difference.

Check Er is the same in both calcs....

It is not with the Saturn pcb, it was with two other online calculators. Yes, I made sure the Er and everything is exactly the same.
