Device Overview
General Description
The MM1-1850S is a high linearity passive double balanced MMIC mixer. The S diode offers superior 1 dB compression, two tone intermodulation performance, and spurious suppression to other GaAs MMIC mixers. It features excellent conversion loss, superior isolations and spurious performance across a broad bandwidth, in a miniature form factor. Accurate, nonlinear simulation models are available for Microwave Office® through the Marki Microwave PDK. The MM1-1850S is available as a wire bondable chip or an SMA connectorized package. The MM1-1850S is a superior alternative to Marki Microwave carrier and packaged M9 mixers.
Features
- CAD Optimized for Superior Isolation and Spurious Response
- Broadband Performance
- Excellent Unit-to-Unit Repeatability
- Fully nonlinear software models available with Marki PDK for Microwave Office®
- RoHS Compliant
Applications
- Test and Measurement Equipment
- Fixed RF up converters
- Electronic warfare equipment
