Fairview Microwave Inc of Allen, TX, USA, which supplies on-demand microwave and RF components, is debuting a new product family of seven unique models of IQ mixer models with RF and LO frequency bands ranging from 4GHz to 38GHz and in-phase and quadrature IF bandwidths ranging from DC to 4.5GHz.
The new monolithic microwave integrated circuit (MMIC) IQ mixers (IQ modulators) utilize gallium arsenide (GaAs) MESFET process technology that integrates a pair of matched double-balanced mixer cells, a 90° hybrid and a 0° splitter/combiner that is said to produce exceptional amplitude and phase balance performance. This level of integration offers size and performance advantages compared with discrete module assemblies.
With the addition of an external 90° IF hybrid module, these IQ mixers can be used as either a single-sideband up-converter mixer or an image reject down-converter mixer. 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.
Performance as an image reject mixer (IRM) includes low conversion loss that ranges from 7.5 to 10dBm, high image rejection up to 35dB typical, and LO-to-RF isolation as high as 42dB typical. The IQ mixer designs offer linearity with input 1dB compression as high as +20dB typical and input IP3 as high as +35dB typical. LO drive power ranges from +15 to +19dBm.
The compact and rugged drop-in package designs are hermetically sealed with field-replaceable connectors and are guaranteed to meet MIL-STD-883 test conditions for humidity and temperature cycle.
All seven models are available from stock and available for immediate shipment.
