I'm no expert either, so, best way to learn is to play.
I do see the reasoning you're putting forth. The CoolMos series from Infineon seems to show some hope here.
Since I'm no expert I'm wanting to order a bunch of "potential players" and do some circuit building and analyses, my 400Mhz scope will happily show a 1Ghz+ signal, but obviously the waveform will be distorted somewhat.
I *do* have an ancient 20Ghz sampling scope too, so hopefully I'll learn a few things and gain some experience trying to push the switching frequency.
Awful part is I need fast components for everything and parasitica are going to play a huge role. Also, solderleas breadboard is out of the question so this will probably be my first try at dead bug breadboarding a high speed circuit.
I'll feel like a moron for a time, but with enough play, I'll probably learn a thing or two.
