The CMD182 is a compact I/Q mixer die that

can be used as either an image reject mixer or a

single sideband upconverter.

utilizes two double balanced mixer cells and a

90 degree hybrid.

An external IF hybrid is

needed to complete the image rejection.

The

CMD182 offers full passivation for increased

reliability and moisture protection.
