The HMC1081 from Analog Devices is a double balanced mixer. It can be used as an upconverter or a downconverter, with DC to 26 GHz at the IF port and 50 to 75 GHz at the RF port. This passive MMIC mixer is fabricated with GaAs Shottky diode technology. All bond pads and the die backside are Ti/Au metallized and the Shottky devices are fully passivated for reliable operation.

The HMC1048LC3B is a general purpose double-balanced mixer that can be used as a downconverter with DC to 4 GHz at the IF port and 2 to 18 GHz at the RF port. This mixer requires no external components or matching circuitry. The HMC1048LC3B provides excellent LO/RF, LO/IF and RF/IF isolation. The mixer operates with LO drive levels from +9 dBm to +17 dBm. The HMC1048LC3B eliminates the need for wire bonding and allows the use of surface-mount manufacturing techniques.
