least 500 mW output with 50 ohm input and output.

A few years ago I made an "impulse buy" from ebay; some Polyfet SP201
FETs. I didn't know what exactly they were but they looked
interesting and didn't cost a lot (because, I suppose, no-one else
knew what they were either).
Subsequent research showed that they are interesting devices. Go to
the Polyfet site;
Go to Application Notes-Num. Order and go to "tb102"; that might
I may try this circuit one day; there are other projects higher on the
The Polyfet site is an interesting browse; they make some nice devices
and their application notes are good reading.
