Overview
The HMC1048LC3BTR is a general-purpose, monolithic microwave integrated circuit (MMIC) double balanced mixer designed by Analog Devices Inc. This component is optimized for use as a downconverter, operating with radio frequency (RF) inputs from 2.25 GHz to 18 GHz and intermediate frequency (IF) outputs from DC to 4 GHz. The mixer is passive, requiring no external DC bias, and it eliminates the need for wire bonding, allowing for surface-mount manufacturing techniques.
