Overview
The HMC774ALC3B is a general-purpose, double balanced mixer produced by Analog Devices Inc. It is designed in a leadless, RoHS compliant, surface-mount package and can be used as either an upconverter or a downconverter within the frequency range of 7 GHz to 34 GHz. This mixer is notable for requiring no external components or matching circuitry, making it highly convenient for integration into various systems. The HMC774ALC3B features optimized balun structures, which provide excellent LO to RF and LO to IF isolation. It operates best with a LO drive level of 15 dBm and eliminates the need for wire bonding, allowing for surface-mount manufacturing techniques.
