And, you can take ESD hits that degrade, but don't destroy, the part.
I've got some LNAs in my desk drawer that appear to work just fine,
except the NF is a bit higher than it used to be.

How do you know it was ESD that caused the degradation?


Oh.. I don't know on the ones in the drawer that's what did it (because
they still work, after a fashion)

That's the reason I asked. Thank you.


Yeah.. the guy or gal who figures out a good non-destructive, no
disassembly required way to detect latent ESD damage is going to be a
hero for those of us building one-off high-rel gear. There have been
some partial solutions for specific parts, but no generalized way, yet.
