Please forgive me if my head's been in the sand, but a while back I saw some
impressive information about the BLF189XRA. Specifically, increased power
level, and significantly better linearity - so good that the typical -11 dBc
third harmonic was so improved, that fewer poles could be used in the harmonic
filter and very little energy would be reflected back to the device.
These seem available, but I don't see any ham amplifiers using them when I do a
web search...
