Features
► Low conversion loss ► High isolation ► Image rejection: 30 dB ► Wide IF bandwidth ► Pb-free RoHs compliant 4x4 mm SMT package
Description
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.
