   By the time you get to the point of mixing, and filtering, those square   
   waves, if you intend to drive an antenna (which for a 'new wifi' chip   
   you do need to eventually drive an antenna) you are back in the analog   
   domain (and squarely in the black magic of high frequency rf design).

   True, but for an item that is a 'radio' transmitter/receiver, 140Ghz is   
   quite impressive.
