HMC521LC4

The HMC521LC4 is a compact I /Q MMIC mixer in a leadless "Pb free" RoHS compliant SMT package, which can be used as either an Image Reject Mixer or a Single Sideband Upconverter. The mixer utilizes two standard Hittite double balanced mixer cells and a 90 degree hybrid fabricated in a GaAs MESFET process. A low frequency quadrature hybrid was used to produce a 100 MHz USB IF output. This product is a much smaller alternative to hybrid style Image Reject Mixers and Single Sideband Upconverter assemblies. The HMC521LC4 eliminates the need for wire bonding allowing use of surface mount manufacturing techniques.
