Hello List-
Maybe I've been away from these topics too long but... aren't
there some general design techniques that solve most of these PCB
level EMC concerns?
For instance- aren't the 20-H rule and the "image plane technique"
still viable at these frequencies? Maybe even more than at lower
frequencies?
I remember these topics being discussed on this list a few years
back. Perhaps one of the old-timers could bring us back up to speed
on the applicability of those to today's problems?
I look forward to hearing what the list thinks.
Best, Gerorge K.
