MGA-22003:2.3-2.7 GHz 3x3mm WiMAX and WiFi Power Amplifier

Avago Technologies MGA-22003 linear power amplifier is designed for mobile and fixed wireless data applications in the 2.3 to 2.7 GHz frequency range. The PA is optimized for IEEE 802.16 WiMAX modulation but can be used for any high linearity applications. The PA exhibits flat gain and good match while providing linear power efficiency to meet stringent mask conditions. It utilizes Avago Technologies proprietary GaAs Enhancement-mode pHEMT technology for superior performance across voltage and temperature levels.

The MGA-22003 is packaged in a 3x3x1 mm package for space-constrained applications.
