Mimix Broadband, Inc. Introduces 18 to 36 GHz GaAs MMIC Transmitter with Integrated Mixer, LO Doubler/Buffer and Output Amplifier

Integrated Transmitter Delivers +25 dBm OIP3 and 35 dB Gain Control

May 30, 2007, Houston, Texas - Mimix Broadband, Inc. introduces today a gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) transmitter that delivers +25 dBm OIP3, 35 dB gain control and 9 dB conversion gain. Using 0.15 micron gate length GaAs pseudomorphic high electron mobility transistor (pHEMT) device model technology, the transmitter covers the 18 to 36 GHz frequency bands and includes a
balanced resistive mixer followed by a distributed amplifier, an LO doubler and an LO buffer amplifier. Identified as XU1009-BD, this device is well suited for point-to-point radio, LMDS, SatCom or VSAT applications.

"This device integrates a number of functional elements into a single MMIC, offering the customer broadband performance with a high level of functionality," stated Paul Beasly, Product Manager, Mimix Broadband, Inc. "The integrated RF buffer amplifier can also be biased down to provide gain regulation, reducing the requirements for attenuation later
in the gain and power stages of the transceiver."

Mimix performs 100% on-wafer RF and DC testing on the XU1009-BD, as well as 100% visual inspection to MIL-STD-883 method 2010. The chip also has surface passivation to protect and provide rugged parts with backside via holes and gold metallization to allow either a conductive epoxy or eutectic solder die attach process.

Production quantities are available today from stock. Technical support is also available from Mimix's applications engineers at 281.988.4600. The datasheet and additional product information can be obtained from the Mimix Broadband website at www.mimixbroadband.com .
