The MQS-0418 is a MMIC 4GHz – 18GHz 90° splitter/combiner. Wire bondable 50Ω terminations are available on-chip. 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-0418 is available as a wire bondable chip and connectorized module. Low variation allows for accurate simulations using the provided S4P file taken from measured production units. The MQS-0418 is not recommended for applications involving reflected signals.

Phase balance spread is shown due to large performance spread. Minimal variance observed in amplitude balance and insertion loss. Performance spread is related to packaging and bond wire inductance variation.
Performance plots for the connectorized module are shown for measurements where directly probed measurements of the die are unavailable. Note that the following measurements include losses from connectors and microstrip traces.
