Mimix Broadband, Inc. introduces its Model XM1003-BD gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) sub-harmonic image reject mixer for use in transmit and in receive frequency conversion applications. Using GaAs HBT technology, this mixer covers the 32 to 42 GHz frequency bands. The device has conversion loss of 9 dB, with 18 dB image rejection and +14 dBm input third order intercept point (IIP3). The mixer is suitable for wireless communications applications such as millimeter-wave point-to-point radio, local multipoint distribution services (LMDS), SATCOM and VSAT. The chip also 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.
