| AFEM-S257 GHz WiMAX Coexistence Front End Module Data Sheet Avago Technologies AFEM-S257 WiMAX Coexistence Front End Module FEM is designed for mobile and fixed wireless data applications in the to GHz frequency range. The FEM is optimized for IEEE WiMAX modulation. AFEM-S257 exhibits flat gain and good match while providing linear power efficiency to meet stringent mask conditions and supports two antenna connections for RX diversity or two simultaneous RX signals. This module utilizes Avago Technologies proprietary GaAs pHEMT, and FBAR technology for superior performance across voltage and temperature levels while providing excellent out of band rejection. AFEM-S257 is in a 5x7x1 mm MCOB package for space-constrained applications. Functional Block Diagram Preselector ByPass LNA ANT-1 ANT-2 T/R-1 ANT SW nfo & OMN T/R-2 RX Div.
