The HMC521ALC4 is a compact, gallium arsenide (GaAs), monolithic microwave integrated circuit (MMIC), inphase quadrature (I/Q) mixer in a RoHS compliant, 24-terminal ceramic leadless chip carrier (LCC) package. This device can be used as either an image reject mixer or a single sideband upconverter. The mixer uses two standard, double balanced mixer cells and a 90° hybrid coupler fabricated in a GaAs, metal semiconductor field effect transistor (MESFET) process. This device is a smaller alternative to hybrid style image reject mixers and single sideband upconverter assemblies. The HMC521ALC4 eliminates the need for wire bonding, allowing use of surface-mount manufacturing techniques. Applications * Microwave and very small aperture terminal (VSAT) radios * Test equipment * Military electronic warfare (EW); electronic countermeasure (ECM); and command, control, communications, and intelligence (C3I) * Downconverter, 8.5 GHz to 13.5 GHz * Conversion loss: 9 dB typical * Image rejection: 27.5 dBc typical * LO to RF isolation: 39 dB typical * Input IP3: 16 dBm typical
