U1004-BD

Mimix Broadband's 32.0-45.0 GHz GaAs MMIC transmitter has a +14.0 dBm output third order intercept across the band. This U1004-BD device is a balanced, resistive pHEMT mixer followed by a distributed output amplifier and includes an integrated LO doubler and LO buffer amplifier. The use of integrated LO doubler and LO buffer amplifier makes the provision of the LO easier than for fundamental mixers at these frequencies. IF and IF mixer inputs are provided and an external 180 degree hybrid is required to select the desired sideband. This U1004-BD MMIC uses Mimix Broadband's 0.15 µm GaAs PHEMT device model technology, and is based upon electron beam lithography to ensure high repeatability and uniformity. The  U1004-BD 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.
