Overview
The HMC558LC3B is a general-purpose double-balanced mixer designed and manufactured by Analog Devices Inc. This mixer is fabricated using a GaAs MESFET process and is housed in a leadless, RoHS-compliant SMT package. It operates as either an upconverter or downconverter within the frequency range of 5.5 to 14 GHz. The device requires no external components or matching circuitry, making it highly integrated and convenient for use in various applications. The HMC558LC3B is notable for its high LO to RF and LO to IF isolation, achieved through optimized balun structures, and it can operate with LO drive levels as low as +9 dBm.
