HMC525LC4 v00.0105 GaAs MMIC I/Q MIXER 4 - 8.5 GHz Typical Applications Features The HMC525LC4 is ideal for: Wide IF Bandwidth: DC - 3.5 GHz • Point-to-Point and Point-to-Multi-Point Radio Image Rejection: 40 dB • VSAT LO to RF Isolation: 50 dB High Input IP3: +23 dBm RoHS Compliant 4 x 4 mm SMT Package Functional Diagram General Description The HMC525LC4 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 HMC525LC4 eliminates the need for wire bonding allowing use of surface mount manufacturing techniques.
