I have read Rf Amplifier Circuit using mosfets on the ARRL Handbook
2002. The amplifier used a pair of Motorola IRF510 transistors to generate 5 or
6 watts of peak envelope power from a 48V supply and operated within the
frequency spectrum of 1.8 to 28 MHz.
The Amplifier is very simple ...you can build at your home.

It might be of
further interest to describe a higher power version of a Rf Amplifier which I had reason to design, using two
IRFP 150. The Circuit can deliver a power off 250w at 1.8 MHz, 300w at 3.5 MHz
and 200w at 7 MHz with 36 v . The IRF150 transistors used were the International
Rectifier (IR) .more detail....
