HMC620LC4

HMC620LC4 v01.1007 GaAs MMIC I/Q MIXER 3 - 7 GHz Typical Applications The HMC620LC4 is ideal for: • Point-to-Point • Point-to-Multi-Point Radio • WiMAX & Fixed Wireless Features Wide IF Bandwidth: DC - 3.5 GHz High Image Rejection: 32 dB High LO to RF Isolation: 43 dB High Input IP3: +22 dBm 24 Lead Ceramic 4x4 SMT Package: 16mm2 8 MIXERS - SMT • VSAT Functional Diagram General Description The HMC620LC4 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 (IRM) 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 upper side band (USB) IF output. This product is a much smaller and more consistent alternative to hybrid style Image Reject Mixers and Single Sideband Upconverter assemblies. The HMC620LC4 is compatible with high volume surface mount manufacturing techniques.
