Mimix Broadband, Inc. Introduces 32 to 42 GHz GaAs MMIC Balanced Mixer

Fundamental Balanced Mixer Optimized for Use as a Down-Converter

April 6, 2005, Houston, Texas - Mimix Broadband, Inc. introduces today a Gallium Arsenide (GaAs) monolithic microwave integrated circuit (MMIC) fundamental balanced mixer, which has been optimized for use as a down-converter. 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 conversion loss of 8 dB with 22 dBm input third order intercept point.

This mixer, identified as XM1000, is well suited for wireless communications applications such as millimeter-wave point-to-point radio, local multipoint distribution services (LMDS) and SATCOM.

"The combination of broad frequency coverage and high linearity is achieved through the use of 'cold FET' mode mixers in a balanced configuration," stated Dr. Jim Harvey, CTO of Mimix Broadband, Inc."This makes the device useful in a wide variety of radio and instrumentation applications."

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 6-8 weeks ARO. Technical support is also available from Mimix's applications engineers at 281.988.4600. The XM1000 datasheet and additional product information can be obtained from the Mimix Broadband website at www.mimixbroadband.com.
