HMC525LC4

MIXERS - I/Q MIXERS, IRMS & RECEIVERS - SMT v03.0514 Typical Applications The HMC525LC4 is ideal for: Point-to-Point and Point-to-Multi-Point Radio VSAT Functional Diagram HMC525LC4 GaAs MMIC I/Q MIXER 4 - 8.5 GHz Features Wide IF Bandwidth: DC - 3.5 GHz Image Rejection: 40 dB LO to RF Isolation: 50 dB High Input IP3: +23 dBm 24 Lead 4x4mm SMT Package: 16mm² 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. Electrical Specifications, TA = +25 °C, IF= 100 MHz, LO = +15 dBm* Parameter Min. Typ.
