Mimix Broadband, Inc. has introduced a gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) fundamental balanced mixer, which has been optimized for use as a downconverter. Using 0.15-micron gate length GaAs pseudomorphic high-electron mobility transistor (pHEMT) device model technology, this mixer covers the 32 to 42 GHz frequency bands. The device has a conversion loss of 8 dB with 22 dBm input third-order intercept point. This mixer, identified as XM1000, is tailored for wireless communications applications such as millimeter-wave point-to-point radio, local multipoint distribution services (LMDS) and SATCOM.

Mimix performs 100% on-wafer RF testing on the XM1000, as well as 100% visual inspection to MIL-STD-883 method 2010. 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.

Samples are available today from stock, and production quantities are available six to eight weeks ARO.
