The subject of the thermal design of the active antenna elements that are
being planned will require some quite serious work to solve the issues being
presented.

But how much power do the FPGAs require?  Of course, it depends on what is
programmed into them and the clock rate.  But I know that in some
applications they require a heat sink, so it can be quite a lot (several
watts) of power.
