Overview
The HMC787LC3B is a general-purpose, double-balanced mixer produced by Analog Devices Inc. This mixer is designed for use in a wide range of frequencies, from 3 GHz to 10 GHz, and can operate as either an upconverter or a downconverter. Fabricated in a gallium arsenide (GaAs) metal semiconductor field effect transistor (MESFET) process, it offers excellent local oscillator (LO) to radio frequency (RF) and LO to intermediate frequency (IF) isolation due to optimized balun structures. The mixer requires no external components or matching circuitry and is packaged in a 12-terminal, RoHS compliant, ceramic leadless chip carrier (LCC) package, which is compatible with high-volume surface-mount manufacturing techniques.
