Ole,

What would be the negative issues trying to attach a FET current buffer
to an LNA in order to make a few watt wideband RF amplifier?

As I am an audio guy I am paralleling this to an audio amp seems simple
a voltage gain stage and then a current gain or buffer stage.

There are plenty of cheap LNA's that are very wideband like this
