Device Overview
General Description
The MQS-0218 is a MMIC 2GHz – 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-0218 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-0218 is not recommended for applications involving reflected signals.
Features
- Designed for C to Ku-band applications
- High amplitude and phase balance
- High isolation
- Low insertion loss
- On-chip 50Ω load terminations
Applications
- Single Sideband Upconverters
- Image Rejection Downconverters
- IQ Modulators
