Mimix Broadband, Inc. Introduces Three Stage Balanced GaAs MMIC Power Amplifier and Complementary Driver Amplifier at 43.5 to 46.5 GHz

Chip Set Produces More Than +26 dB Gain and 1-Watt of Output Power

March 15, 2005, Houston, Texas - Mimix Broadband, Inc. announced today the introduction of a Gallium Arsenide (GaAs) monolithic microwave integrated circuit (MMIC) three stage balanced power amplifier and complementary three stage driver amplifier. Both the balanced power amplifier and the driver amplifier use 0.15 micron gate length GaAs pseudomorphic high electron mobility transistor (pHEMT) device model technology. The power amplifier has a balanced design to achieve good output match and covers the 43.5 to 46.5 GHz frequency bands, and has a small signal gain of 13 dB with +29 dBm P1dB compression point. The driver amplifier covers this same frequency band, and achieves a small signal gain of 13 dB with +24 dBm P1dB compression point. Used as a driver and final stage cascade, this chip set achieves +26 dB gain and 1-watt output power.

The balanced power amplifier and driver amplifier, identified as 44MPA0478 and 44MPA0470 respectively, are ideal for wireless communications applications such as millimeter-wave point-to-point radio, local multipoint distribution services (LMDS), and SATCOM applications.

"This chip set provides greater than 1-watt saturated power at 44 GHz, and can be used with our integrated up-converters to provide a complete transmitter chain," stated Dr. Jim Harvey, CTO of Mimix Broadband, Inc.

Mimix performs 100% on-wafer RF, DC and output power testing on the 44MPA0478 and 44MPA0470, 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.

Engineering 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.
