Mimix Broadband, Inc. Introduces High Gain GaAs MMIC Buffer Amplifiers that Deliver +20 dBm P1dB

Versatile buffer amplifier pair covers 4-21 GHz for PTP applications

February 26, 2007, Houston, Texas - Mimix Broadband, Inc. introduces today two gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) two stage buffer amplifiers. Using 0.15 micron gate length GaAs pseudomorphic high electron mobility transistor (pHEMT) device model technology, these buffer amplifiers, identified as
XB1007-BD and XB1008-BD, cover 4 to 11 GHz and 10 to 21 GHz, respectively. Both devices deliver +20 dBm P1dB compression point and +30 dBm OIP3. The XB1007-BD has a noise figure of 4.5 dB and 23 dB small signal gain; the XB1008-BD has a noise figure of 5.5 dB and 18 dB small signal gain. These buffer amplifiers are ideal for wireless
communications applications such as millimeter-wave point-to-point radio, local multipoint distribution services (LMDS), SATCOM and VSAT applications.

"These two buffer amplifiers offer a combination of broadband operation, output power and compact dimensions to provide a cost-effective solution for frequencies from 4 to 21 GHz," stated Paul Beasly, Product Manager of Mimix Broadband, Inc. "The compact 1.2 square millimeter die with wideband return loss operation is consistent with broadband use in a variety of frequency and functional applications."

Packaged versions of the XB1007-BD and XB1008-BD in fully molded, plastic 3x3 QFN packages will be available in the near future for surface mount applications.

Mimix performs 100% RF, DC and output power testing on the XB1007-BD and XB1008-BD, as well as 100% visual inspection to MIL-STD-883 method 2010. The chips also have 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.

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