Pasternack has introduced six new IQ mixer models with RF and LO frequency bands ranging from 4 GHz to 38 GHz and In-Phase and Quadrature IF bandwidths ranging from DC to 4.5 GHz. The applications of the new mixer series include point-to-point and point-to-multipoint radio, VSAT, Military Radar, EW, Satellite Communications, sensors, and test and measurement equipment.
The new IQ Mixer modules are composed of MMIC based assemblies which use a highly reliable GaAs MESFET semiconductor process that consists of a pair of matched double-balanced mixer cells, a 90-degree hybrid and a 0-degree splitter/combiner. This level of integration offers advantages in size and performance when compared to discrete module assemblies. With the addition of an external 90 degree IF hybrid module, these IQ Mixers can be configured as an Image Reject Mixer (IRM) or Single Sideband Up-converter Mixer. Image rejection and sideband suppression reduce overall system cost and complexity by removing the need for pre-selection filtering.
These IQ Mixers can be used as Image Reject Mixers as they have a low conversion loss that ranges from 7.5 to 10 dBm, high image rejection up to 35 dB typical, and LO to RF Isolation up to 42 dB. These designs offer excellent linearity with input 1 dB compression as high as +20 dB typical and Input IP3 as high as +35 dB typical. LO drive power ranges from +15 to +19 dBm.
The models are available in hermetically sealed Kovar drop-in metal packages that are gold-over-nickel-plated and support field-replaceable SMA connectors. All units are RoHS compliant, export classified as EAR99, and guaranteed to meet MIL-STD-883 environmental test conditions for fine and gross leak and temperature cycle.
