I checked the Hittite/AD part at Mouser, $21 and change. Problem is,
they have a few, but it is marked obsolete/discontinued. Also, a
devilish package to work with. . .

Hi
The noise floor of the double balanced mixer (used as a phase
detector at 100 MHz) is in the -165 go -170 dbc / Hz range. I've
used the parts you are talking about. Their floor is *way* higher.

I stated the MC100EP140 would not match the Hittite HMC984LP4E. It has
-231 dBc/Hz noise.
-231 dBc is *way* lower than -170 dbc. About 60 dB lower.
You might be interested in trying it. Only $13.25 at Arrow:
