Mimix Broadband Inc. announced the XP1003 GaAs monolithic microwave integrated circuit (MMIC) power amplifier optimized for linear operation. This two-stage power amplifier is well suited for modulation levels up to 64 QAM and has a typical third-order intercept point of 34dBm.

The XP1003 also includes Lange couplers to achieve good input/output return loss and has a small signal gain of 16dB across the band. Using 0.15?m gate length GaAs pseudomorphic high electron mobility transistor (pHEMT) device model technology, this chip covers the 27GHz to 35GHz frequency band.

Target applications for the new power amplifier include wireless communications applications such as millimeter-wave point-to-point radio, local multipoint distribution services, SATCOM and VSAT applications.

Mimix performs 100 percent on-wafer RF, DC and output power testing on the XP1003, as well as 100 percent 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 from stock and production quantities are available within six to eight weeks after order processing.
