Here's a link to one manufacturer

Yep, that's them alright. The one we have is the electrostatic version.

I took a closer look over a wider frequency range at its response and -- not
too surprisingly -- it's a straight line on a log-log plot (i.e., the coupling
is almost purely capacitive).

Thanks for everyone's help,
---Joel

I don't know what Butches point was....


I think I was close, no? Don't they have a number and name stamped on them?
Usually uLab does that. Google is mighty powerful in this regard.
