Fortunately, in Finland we don't have too many problems with that. Sale

So things like the PRC-148 aren't really commercially available.
That's a military handheld for sale to governments. I don't think that
Military radios need to meet some of the same requirements as
commercially available radios. Not having taken a PRC-148 apart, I'm
not sure what the innards look

AFAIK, there is a commercial version which lacks the military software

I spotted this discussion midway.
Here are a few thought on the matter from an Amateur Radio operator
perspective.
Depending on the frequencies in question you can use several COTS amplifiers
for specific bands needed, and use a Diplexer/Triplex/Quad... (basically
filters to separate the bands.)

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.

Hi,
are there any manufacturers besides Ettus that offer boards for the USRP
or offer custom boards? I would especially be interested in something
WBX-y with 5+ or even 25+W ERP.
Using an external amplifier does not exactly make sense on a 2.15GHz
