Description: I made a development board for this part, a Minicircuits MIQC-895 I/Q mixer, and mounted the RF component with SMA connectors for the LO input and RF In/Out. You are buying an assembled board. You can slip SMA's on the I & Q IF ports or use coaxial cables/ plain wires to attach the IF connections. The description below is for the RF part, now the hard work has been done for you. I plan to use a pair of these in my Communications classroom demos here at the Space Science Center. Very handy for tinkering with if you ever wanted to explore I/Q mod-demod systems. 900 MHz is an ISM band so you can do low level over the air testing. Two are shown for clarity, you are buying one. The following is from my advert for the bare RF part:The MIQC-895M is a very interesting part made by Mini Circuits Labs, I/Q modulator type , obviously made for the 900 MHz band, very complex and expensive part (cost 104.00 new!!) I have limited knowledge on the topic, but cannot see why it cant be used for a direct conversion receiver as well as the upconverter modulator for a transmitter. Has LO in (860-900 MHz), two direct coupled IF ports, I&Q, DC-5 MHz bandwidth, and RF out! Since this is a passive part, why not use it for a downconverter as well! What it does is combine the LO quadrature splitter and RF in-phase splitter in a box with 2 very well matched double-balanced mixers. Nice for experimenting with signal generation! Quad coupler will limit bandwidth to over an octave or so, depending on what EVM you can tolerate or what degree of S/W correction you apply, and as phase relationship moves away from 90 degrees, there is a degradation of carrier suppression in the system, but I still think useful to 1000 MHz maybe a little higher, especially for ham work. Neat part! With data sheet, new old stock. Have fun! Please see my other stuff for more RF goodies and remember I will gladly combine items to save you shipping!
