CMD252C4 Mixer

4-8 GHz (C Band) I/Q Mixer

The CMD252C4 is a compact 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 CMD252C4 utilizes two double balanced mixer cells and a 90 degree hybrid. An external IF hybrid is needed to complete the image rejection. The CMD252C4 is a much smaller alternative to higher cost hybrid image reject mixers and single sideband upconverter assemblies.


  • High isolation
  • Image rejection: 30 dB
  • Low conversion loss
  • Pb-free RoHS compliant 4x4 mm SMT package
  • Wide IF bandwidth

Custom MMIC Space Qualified MIMCs
Space Qualification

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" or "Mission Specific" and are often available from stock. Our "Mission Specific" devices are screened based on custom applications where screening is derived from MIL requirements and tailored specific to customer needs. Just let us know when requesting price and delivery, or technical support, if your devices will be used in space.
