Overview
The HMC520ALC4, produced by Analog Devices Inc., is a compact gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) in-phase quadrature (I/Q) mixer. It is housed in a 24-terminal, RoHS compliant, ceramic leadless chip carrier (LCC) package. This device can be used as either an image reject mixer or a single sideband upconverter. The HMC520ALC4 utilizes two standard double balanced mixer cells and a 90° hybrid fabricated in a GaAs metal semiconductor field effect transistor (MESFET) process. It eliminates the need for wire bonding, allowing the use of surface-mount manufacturing techniques, making it a smaller and more efficient alternative to hybrid style mixers and upconverters.
