For the rest of the group I pose a question: If we assume that we are going to modulate the downlink with BPSK, can we get away with hard limiting (i.e. Class-C) amplifier? Do we really care about occupying a spectrum about twice as wide as "best engineering practice"?

We intend flying unfiltered BPSK and as efficient an amplifier as we can build. This will not be a problem as I see it.
