10 GHz Signal Source
YIG Series
The SC5503B and SC5502A are designed to meet demanding low phase noise applications. This is accomplished by employing a multiple phase-locked loop architecture as well as a YIG oscillator as the heart of its synthesizer. Frequency accuracy is provided by an onboard 10 MHz temperature compensated crystal oscillator (TCXO) which can be phase locked to an external reference source if required. These modules can be used as standalone CW signal sources or as LO sources for frequency conversion systems such as the SignalCore IQ modulators and demodulators. They are designed to meet the requirements of many modern applications such as wireless device testing, software-defined radio research, point-to-point radio, multi-channel coherent systems, and other academic and military programs.

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.
