 How high a frequency has anyone here done?  Any tips or
 suggestions to offer?
 
 Anyone doing anything in the THz range yet (yes, that is a 'T')?

I have done 480THz. But it gets demodulated soon at the beginning of the
signal path.

10's of EHz. The challenge up there is to measure the energy of the  
photoelectron.

Hire a physicist ;-)

Well, you're looking at wave optics at THz frequencies, not printed  
circuits.
