Hi all.
I am in the possession of a MCL ZMIQ-895M-1 IQ-modulator/demodulator, but can not locate a data sheet. Neither on the MCL web-page nor on the Internet as a whole.
Can it be so lucky that someone here does have such a data sheet?
My intention is to use it for a Image reject Down-converter for 87.5 to 108 MHz to HF in order to fully utilize the RX-888 BW for the BC-FM band.
Just like in this post:

Happy to get any hints where to find such a data sheet.

IQ-modulator data sheet
Re: IQ-modulator data sheet
Hi.
I did some guesswork on LO-power (+15 dBm at 80 MHz) and added a PSCQ-2-50 at the I&Q-terminals of the ZMIQ-895M-1 and got ~10 dB of Conversion Loss over the BC-FM band and some 30 dB image rejection from ~50 to 70 MHz.
A 3-pole Band Pass LC-filter (85 - 110 MHz) between a PGA-103+ LNA and the Image rejection mixer plus a simpler filter at the input of the LNA and it will probably be a nice down converter together with the RX-888.
Looking at the full BC-FM band in one chunk.
However, I am still in for a full data sheet. If someone knows where to find it.
