The HMC260LC3B is a general purpose double balanced mixer in a leadless RoHS compliant SMT package that can be used as an upconverter or downconverter between 14 and 26 GHz. This mixer requires no external components or matching circuitry. The HMC260LC3B provides excellent LO to RF and LO to IF suppression due to optimized balun structures. The mixer operates with LO drive levels above +9 dBm. The HMC260LC3B eliminates the need for wire bonding, allowing use of surface mount manufacturing techniques.
