Yes you can use a upconverter to a standard 5 ghz card.
I will try this to but for the 10 ghz range .
But i thing you have to built all the gear by your self or check this site they can help you out http://www.procom-dk.com/ they built feeders and parabolics osv..
over 5ghz so 10ghz and more it is hard to buil long-stable link, becouse of wether, temp - can not allowed to use it... With frequency distance is lower.
