Mimix Broadband, Inc. Introduces 12 to 34 GHz GaAs MMIC Image Reject Mixer Optimized for Use as Down-Converter

Wide Bandwidth Mixer Offers Low Conversion Gain

December 8, 2004, Houston, Texas - Mimix Broadband, Inc. introduces today a Gallium Arsenide (GaAs) monolithic microwave integrated circuit (MMIC) image reject mixer that covers the 12 to 34 GHz frequency bands. The image reject mixer, identified as 20IRRFM0374, has a conversion loss of 8 dB, a +15 dB image rejection across the band, and an input referred third order intercept greater than +24 dBm over that band. It is well suited for wireless communications applications such as millimeter-wave point-to-point radio, local multipoint distribution services (LMDS) and SATCOM.

"The exceptional bandwidth and linearity of this part make it useful for a wide range of applications," stated Dr. Jim Harvey, CTO of Mimix Broadband, Inc. "The use of fundamental 'cold FET' topology facilitates the design of high performance wide band mixers with high linearity. Where high linearity is not required, the LO drive can be reduced while maintaining good conversion loss." Mimix performs 100% on-wafer RF testing on the 20IRRFM0374, 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.

Engineering 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 20IRRFM0374 datasheet and additional product information can be obtained from the Mimix Broadband website at www.mimixbroadband.com.
