Let me preface this by saying I mostly lurk on this list, and haven't
touched a USRP of any variety, so I'm unfamiliar with their gain lineup.
However, looking at this data, a couple of things come to mind.

That's a pretty aggressive goal, to hit 5W over the USRP BW. To get
reasonable linearity, you're probably looking at something that draws
25W of DC power. An external Amp is probably off the shelf. For
example, Minicircuits has a TIA-1000 that does 4+ watts out from 100
to 1000 MHz for $2000.
Very interesting change of direction from Verizon. It will be
interesting to see what Qualcomm does if a couple of guys in a garage
come calling for some CDMA chipsets.

I have to say that I like dBs, too. All you have to do is remember two

You may well be able to do it with the DBS board. However, GPS is a

The DBS board has about a 3-5 dB noise figure as I recall, but that
