The HMC774A is a general purpose double balanced mixer chip that can be used as an upconverter or downconverter between 7 and 43 GHz. This mixer requires no external components or matching circuitry. The HMC774A provides excellent LO to RF and LO to IF isolation due to optimized balun structures. The mixer operates with LO drive levels of +13 dBm. The HMC774A wideband mixer exhibits consistent conversion gain and compression across its bandwidth. The HMC774A is also available in SMT format as the HMC774ALC3B.
