HMC523LC4 v02.1208 MIXERS - I/Q MIXERS, IRMS & RECEIVERS - SMT 8 GaAs MMIC I/Q MIXER 15 - 23 GHz Typical Applications Features The HMC523LC4 is ideal for: Wide IF Bandwidth: DC - 3.5 GHz • Point-to-Point Radios Image Rejection: 25 dB • Point-to-Multi-Point Radios & VSAT LO to RF Isolation: 47 dB • Test Equipment & Sensors High Input IP3: +25 dBm • Military End-Use RoHS Compliant 4x4 mm SMT Package Functional Diagram General Description The HMC523LC4 is a compact general purpose I /Q MMIC mixer in a leadless 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 HMC523LC4 eliminates the need for wire bonding allowing use of surface mount manufacturing techniques. Electrical Specifi cations, TA = +25° C, IF= 100 MHz, LO = +17 dBm* Parameter Min.
