In-Phase / Quadrature (IQ) Mixer Product Line for RF Microwave and Millimeter Wave Announced by Pasternack
Pasternack IQ (In-Phase / Quadrature) Mixer Components Avaialble for Same Day Shipping
RF microwave and millimeter wave in-phase / quadrature IQ mixer components are announced by Pasternack. These new IQ mixer product line has 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. Typical applications for In-phase and Quadrature IQ RF mixer components 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 I/Q Mixers can be configured as an Image Reject Mixer or Single Sideband Upconverter Mixer. Image rejection and sideband suppression can reduce overall system cost and complexity by removing the need for pre-selection filtering.
The RF Mixers’ performance as an Image Reject Mixer (IRM) includes 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 typical. These in-phase / quadrature 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.
These I/Q mixer models are offered 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.
