Since the semi manufactures stopped making Bipolar RF Power transistors

Intermodulation
Distortion (IMD) standards.
*** I'm guessing that 12V is just really minimal for these MOSFETS, is
that
right? I'm kitting up for a homebrew project right now - the design
uses
a 12V-24V converter to get decent voltage for a 25W output stage.
