A good place is to talk with the apps engineers of your
PCB fabricator, -if they are not familiar with most economic
stack for your high frequency application then it is probably
time to find a shop that is..
You can find a primer on controlled impedance covering
differential traces and other high frequency issues at:
Hope this helps
