General Description
The HMC557LC4 is a general purpose double balanced mixer in a leadless RoHS compliant SMT package that can be used as an upconverter or downconverter between 2.5 and 7 GHz. This mixer is fabricated in a GaAs MESFET process, and requires no external components or matching circuitry. The HMC557LC4 provides excellent LO to RF and LO to IF isolation due to optimized balun structures and operates with LO drive levels as low as +9 dBm. The RoHS compliant HMC557LC4 eliminates the need for wire bonding, and is compatible with high volume surface mount manufacturing techniques.
