MGA-22003 2.3-2.7 GHz 3x3mm WiMAX and WiFi Power Amplifier Preliminary Data Sheet Description Features 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. * Advanced GaAs E-pHEMT The MGA-22003 is packaged in a 3x3x1 mm package for space-constrained applications. * 3 to 5V supply * ESD protection all ports above 1000V HBM * Small size: 3 x 3 x 1 mm * Stable under all loads or conditions * Gain of 35dB * WiMAX and WiFi Access points * PAE of 21% Functional Block Diagram * Meets ETSI/802.16 masks at 25 dBm Pout , 16QAM WiMAX with 3.3V and 485mA * 16QAM WiMAX EVM < -32dB (2.5%) at 25dBm VCC2 13 * Low power Idd, 200mA, 27dB gain at 12dBm Pout VCC2 GND 13 RFIN 1 12 GND GND 2 11 RFOUT GND 3 10 GND BCTRL 4 9 NC 17 5 0.15 0.10 N/C 8 6 7 8 0.30 0.10 0.60 0.10 14 0.20 0.10 15 0.30 0.10 N/C 9 16 NC GND 10 BCTRL 4 PAMOD 7 1.00 0.10 1.50 0.10 BIAS NETWORK BSW 6 3.00 0.10 RFOUT 11 GND OMN ISMN Package Diagram BSW PMOD GND 2 * Low Power Idsq of 110mA VCC1 GND 12 BSPLY GND 14 3.00 0.10 1.50 0.10 VCC1 15 RFIN 1 BSPLY 5 * Integrated CMOS compatible pins for shutdown and low power mode At 2.5GHz * Portable WiMAX and WiFi applications GND 3 * 8dB gain attenuation in low power mode with Idsq reduction * -40C to +85C operation Applications GND 16 * 50 all RF ports TOP VIEW THROUGH PACKAGE This preliminary data is provided to assist you in the evaluation of product(s) currently under development.
