Device Overview
General Description
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. The MQS-0218SM is not recommended for applications involving reflected signals.
