The PA transistor he is showing there certainly has the capability of
producing the 10W. I have been looking at that one for some of my
projects. Without going through a full circuit analysis, it looks like
a fairly straightforward basic transverter,. It uses dual gate MOSFETs
for mixers with no LNA, so I would be concerned about the NF and third
order intercept point. It looks like it uses diode switching for the
T/R switching. Looks like some packaged 97 MHz commercial oscillator
for the LO; would like to know what the accuracy and stability of that
is as well.
