Overview
The HMC521LC4 is a compact, gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) in-phase quadrature (I/Q) mixer, designed and manufactured by Analog Devices Inc. This device is housed in a RoHS compliant, 24-terminal ceramic leadless chip carrier (LCC) package. It can be used as either an Image Reject Mixer or a Single Sideband Upconverter, making it a versatile component for various microwave applications. The mixer utilizes two standard double-balanced mixer cells and a 90-degree hybrid, fabricated in a GaAs MESFET process, ensuring high performance and reliability.
