Mimix Broadband, Inc. Introduces 17 to 24 GHz GaAs MMIC Power Amplifier with Temperature Compensated Power Detector

Power Amplifier Operates as Excellent Transmit Output Stage with +27 dBm P1dB

April 30, 2007, Houston, Texas - Mimix Broadband, Inc. introduces today a gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) three stage power amplifier featuring an on-chip temperature compensated output detector. Using 0.15 micron gate length GaAs pseudomorphic high electron mobility transistor (pHEMT) device model technology, the power amplifier covers the 17 to 24 GHz frequency bands and has a small signal gain of 18 dB with +27 dBm P1dB compression point. The XP1019-BD die is an excellent buffer or output transmit amplifier and is ideal for millimeter-wave point-to-point radio communications and military applications.

"The XP1019-BD is well suited as a transmit output stage for saturated applications or as a high-power buffer amplifier for linear applications," stated Paul Beasly, Product Manager, Mimix Broadband, Inc. "The device has an on-chip output power detector that can be used to regulate the power level and has the added feature of power control -
varying the drain current enables current savings without significant linearity sacrifice. These features allow the device to be operated as a variable gain amplifier, adding greater functionality and performance enhancements for our customers."

Mimix performs 100% RF, DC and output power testing on the XP1019-BD, as well as 100% visual inspection to MIL-STD-883 method 2010. The chips also have near hermetic 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 .
