Mimix Broadband, Inc. has introduced a gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) subharmonic image reject mixer for use in transmit and receive frequency-conversion applications. Using GaAs HBT technology, this mixer covers the 32 to 42 GHz frequency bands. The device exhibits a conversion loss of 9 dB, with 18 dB image rejection and a +14 dBm input, third-order intercept point (IIP3).

The mixer, identified as XM1003-BD, is well suited for wireless communications applications such as millimeter-wave point-to-point radio, local multipoint distribution services (LMDS), SATCOM and VSAT.

"The XM1003-BD offers a very low-cost solution for up- and down-conversion applications over the 32-42 GHz frequency band," stated Paul Beasly, product manager, Mimix Broadband, Inc. "It utilizes a passive, sub-harmonic mixer technology that makes it quite versatile and easy to implement for a wide range of applications."

Mimix performs 100% on-wafer RF testing on the XM1003-BD, as well as 100% visual inspection in accordance with MIL-STD-883, method 2010. The chip also has surface passivation to protect and provide a rugged device with backside via holes and gold metallization to allow either a conductive-epoxy or eutectic-solder, die-attach process.

Engineering samples are available from stock; production quantities will become available within 12 weeks.
