HI
I have no direct experience with the Minicircuits "active mixers", but I
have used some of their amplifier chips. I suspect they use their own amps.
Or at least the same amps.
The amps I worked with had significant phase noise issues when driven
within 6db of their 1db compression point. They were "ok" at low drive
levels. More or less then went from 3 db noise figure to a > 20 db nf as
you went from -20 dbm to 0 dbm output on a +7 dbm amplifier.
Uhm, that sounds more like distorsion than noise. Anyway, if it is the
same amps, then that would exclude them from being suitable for driving
the mixer to saturation. Thanks for the report.
Cheers,
Magnus
