MACOM’s 32.0-42.0 GHz GaAs MMIC sub-harmonic image reject mixer can be used as an up- or down-converter. The device has a conversion loss of 9.0 dB with 18.0 dB image rejection across the band. I and Q mixer outputs are provided and an external 90 degree hybrid is required to select the desired sideband. This MMIC uses MACOM’s GaAs HBT device model technology, and is based upon electron beam lithography to ensure high repeatability and uniformity. The chip has surface passivation to protect and provide a rugged part with backside via holes and gold metallization to allow either a conductive epoxy or eutectic solder die attach process. This device is well suited for Millimeter-wave Point-to-Point Radio, LMDS, SATCOM and VSAT applications.
