Overview
The HMC558ALC3B is a general-purpose, double-balanced mixer produced by Analog Devices Inc. This mixer is designed in a leadless, RoHS-compliant surface-mount technology (SMT) package and can be used as either an upconverter or downconverter within the frequency range of 5.5 GHz to 14 GHz. Fabricated using a gallium arsenide (GaAs) metal semiconductor field effect transistor (MESFET) process, the HMC558ALC3B requires no external components or matching circuitry. It provides excellent isolation between the local oscillator (LO), radio frequency (RF), and intermediate frequency (IF) signals due to optimized balun structures and operates with LO drive levels as low as 9 dBm.
