Mimix Broadband Introduces GaAs pHEMT MMIC Two Stage Power Amplifier Optimized for Third Order Intercept Point (IP3)

Source: Mimix Broadband

Designed for Millimeter-wave Point-to-Point Radio, LMDS, SATCOM and VSAT Applications

Houston, Texas. Mimix Broadband announced today the introduction of a gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) two stage power amplifier optimized for linear operation with a typical third order intercept point (IP3) of +36 dBm. 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 band and has a typical small signal gain of 18 dB. Furthermore, this device includes Lange couples to achieve good input/output return loss (15 dB) and an on-chip temperature compensated output power detector.

This power amplifier, identified as XP1000, provides equipment designers with a highly optimized product with good linearity and is well suited for wireless communications applications such as millimeter-wave point-to-point radio, local multipoint distribution services (LMDS), SATCOM and VSAT applications.

"This power amplifier, XP1000, has a high ratio of OIP3 to P1dB, and is intended for use in QAM radios where linearity and accurate determination of maximum RF power level are critical," stated Jim Harvey, CTO of Mimix Broadband. "In 16 to 128 QAM radios, the final amplifier is backed off to achieve the required adjacent channel power levels. The tightly integrated temperature compensated detector allows operation close to the maximum allowable power level."

Mimix performs 100% on-wafer RF, DC and output power testing on the XP1000, 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 within 10 to 12 weeks after order processing. Technical support is also available from Mimix s applications engineers at 281.526.0536. Additionally, please visit Mimix s website (www.mimixbroadband.com) for the XP1000 datasheet and additional product information.
