The CMD257C4 is a high IP3 I/Q mixer in a leadless surface mount package that can be used as either an image reject mixer or a single sideband upconverter. The CMD257C4 utilizes two double balanced mixer cells and a 90 degree hybrid. An external IF hybrid is needed to complete the image rejection. The CMD257C4 is a much smaller alternative to higher cost hybrid image reject mixers and single sideband upconverter assemblies.

We are proud to announce a new technical brief illuminating our progress in eliminating complex bias sequencers and negative voltage supply. Our expert engineers have been exploring the use of enhancement mode
In addition to offering delivery from stock on our own evaluation boards for nearly all our die and packaged devices, Custom MMIC has also put nearly 30% of our devices into the X-Microwave block system. This drop-in simulation, prototyping, and production system enables efficient and expedient microwave and millimeter-wave circuit development and testing.
Custom MMIC strives to design all our MMIC devices in a manner such that they can be readily chosen for your space applications. We offer turnkey space screening / testing service when a device is categorized as "Ready for Space Screening" on our website. In some cases, our devices have already been "Space Qualified" and are often available from stock. Just let us know when requesting price and delivery, or technical support, if your devices will be used in space.
