Using my memoryfag powers here…
I read an article about 20 years ago about Gallium Nitride amplifiers. They were supposed
to be able to put out 10 times the power at 1/3 the heating of silicon devices. This means
something could be 30 times smaller and lighter. I said at the time that "this could be the
next big leap in power devices."
Apparently, they are just now becoming commercially viable. The article I read had
to do with university research into them.
I found a link to iridium gallium nitride on wikipedia if anyone wants to check it out.
It probably has nothing to do with this guy, though.
