Overview
The HMC787ALC3B is a general-purpose, double-balanced mixer produced by Analog Devices Inc. This component is designed for use as either an upconverter or downconverter within the frequency range of 3 GHz to 10 GHz. Fabricated in a gallium arsenide (GaAs) metal semiconductor field effect transistor (MESFET) process, the HMC787ALC3B offers excellent local oscillator (LO) to radio frequency (RF) and LO to intermediate frequency (IF) isolation due to its optimized balun structures. The mixer operates with a LO drive level of 17 dBm and does not require any external components or matching circuitry. It is packaged in a 12-terminal, RoHS compliant, ceramic leadless chip carrier (LCC) package, which is compatible with high-volume surface-mount manufacturing techniques.
