An IQ mixer is a special mixer that has quadrature IF outputs. It is different from an IR/SSB mixer because it put data in both sidebands around the LO, but with different phase such that the two data signals can be retrieved independent of each other. The I and Q inputs to the mixer will show up 90° out of phase with each other on the RF side, and can then be retrieved using another IQ mixers.

Electrical Specifications - Specifications guaranteed from -55 to +100°C, measured in a 50-Ohm system.
