Most of my RFish work is in the 900-2400MHz range (with lower IF's
of course). I've seen the effects recently as low as 8-900MHz, and
I vaguely remember seeing it lower (400-500MHz?) with a large value
(100-200pF?) cap used as a DC block. So we're not talking "white
light" frequency wise. It's still somewhat high frequency for
typical SI, but it's getting close.
At the lower frequencies, say 50-100MHz, we get to relax a bit ;)
Sometimes we still get bit tho', forgetting that electrons will
be electrons even at "DC".
