If I was designing a UHF PA, I'd choose FETs these days!

Alas, if automobiles used 48V instead of 12 ;-)

They will.

A few years ago 42 V (3x14 V) was supposed to be the new automobile
voltage, but I have not heard much of it lately :-).

I read about the engineering and design that was going into the "new
48V automotive systems" in the IEEE Spectrum in the last year or so.

A brief Google search of ieee.org did not locate the article for me.
