That's the way to go for RF stuff. Although it does get old for larger concoction of logic chips, bus decoders and so on.

...and above a couple hundred MHz or thereabouts, if you have any matching or filter networks you'll end up re-tuning the real PCB anyway due to the significant difference in parasitics. Probably not a big deal, though.


Hold the tomatoes but I have done UHF stuff on double-sided phenolic, including stripline resonators.


I'm actually surprised that there isn't a lot of noise or loop instability problems with John's switcher... even with switchers operating at at the mid-hundreds of kHz, I've seen multi-inch wires cause problems.


It's sometimes amazing what you can get away with in prototyping. Except with high power circuits where it may be a good idea to wear eye protection.
