Overview
The HMC521LC4TR is a compact, gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) in-phase quadrature (I/Q) mixer produced by Analog Devices Inc. This device is designed to operate as either an image reject mixer or a single sideband upconverter. It features two standard double-balanced mixer cells and a 90° hybrid, fabricated in a GaAs MESFET process. The HMC521LC4TR is packaged in a RoHS-compliant, 24-terminal ceramic leadless chip carrier (LCC) or 24-TFQFN exposed pad package, making it suitable for surface mount manufacturing techniques.
