IQ Mixers

The new MMIC IQ mixers from Fairview (also known as IQ modulators) utilize a highly reliable GaAs MESFET semiconductor process which integrates a pair of matched double balanced mixer cells, a 90-degree hybrid and a 0-degree splitter/combiner that produces exceptional amplitude and phase balance performance. This level of integration offers size and performance advantages in comparison to discrete module assemblies. With the addition of an external 90-degree IF hybrid module, these IQ mixers can be used as either a Single Sideband Up-converter Mixer or an Image Reject Down-converter Mixer. The benefit of image rejection and sideband suppression can reduce overall system cost and complexity by removing the need for pre-selection filtering. Typical applications include point-to-point and point-to-multipoint radio, VSAT, military radar, electronic warfare, satellite communications, test equipment, and sensors.
