Does anyone have any useful calculations or links to material covering good ways to calculate signal loss through vias?

What would be perfect is a graph with typical loss in dB over the range 1GHz to 10Ghz+

I'm calculating the total signal loss of some 10G SerDes traces, in order to work out the required pre-emphasis.

  • Don't you have access to some simulation software like Hyperlynx ? Because, doing computation "by hand" with this kind of frequency will result in a gross value. That's helpful if it's to help you choose a range of pre-emphasis, you can assimilated your via to a trace, with some kind of majoration. But if you want a precise value for your pre-emphasis, you need to use a simulation software. – zeqL Feb 27 '14 at 21:58

It certainly appears to tell you several things about vias at RF and it's free.
