Why not use something like an HP5254B/C ? They give out 50MHz harmonics up to the low Ghz region, all filtered by a nice high-Q tuneable cavity. All to typical HP build quality. Of course, they have an amount of 'not needed' circuitry and are just a bit ..... , well, bulky. Good clean output from 10MHz in though.
I guess I wasn't totally clear in my original post. I was looking for ideas on circuits - I'm trying to fit this into a few square cm of board real estate.
Sadly, if you put the 5254 into a big crusher and squeeze it down to the few cm size, the harmonic content seems to drop off dramatically <grin>
I've got some fast Schottky diodes on order for another purpose, so I may breadboard the Wenzel circuit and see how it works. I'm thinking the 1N914 in the Wenzel article might not work so well at 100MHz. I might not wind up using it this time, but it's useful to try it.
