The MQS-0218SM is a MMIC 2GHz – 18GHz 90° splitter/combiner. Passive GaAs MMIC technology allows production of smaller constructions that replace larger form factor circuit board constructions. Tight fabrication tolerances allow for less unit to unit variation than traditional splitter/combiner technologies. The MQS-0218SM is available as a 4 x 4 mm QFN package. Evaluation boards are also available. Low variation allows for accurate simulations using the provided S3P file taken from measured production units. Applications include single sideband upconverters, image rejection downconverters, IQ modulators, balanced amplifiers, and microwave correlators. The MQS-0218SM is not recommended for applications involving reflected signals.

The electrical specifications apply at TA=+25°C in a 50Ω system. Min and Max limits are guaranteed at TA=+25°c
