Front-end Module Enables WiMAX-Coexistence Operation on Same Device

Wed, 06/01/2011 - 5:51am
front end module WiMAXAvago announced a complete RF front-end module (FEM) for WiMAX radios in mobile handset or portable PC applications. The AFEM-S257 module is designed for coexistence operation of WiMAX with other cellular and WiFi radios in the same device. The module features two receive ports and a single transmit port in a small 5 mm x 7 mm x 1 mm package that is appropriate for space-constrained mobile applications in the 2.5 to 2.7 GHz frequency range. Using the company’s 0.25-µm GaAs enhancement-mode pHEMT process and leading-edge Film Bulk Acoustic Resonator (FBAR) filtering technologies, the module delivers desirable performance across voltage and temperature levels. FBAR technology delivers steep roll-off and low insertion loss, resulting in extended battery life and talk time and better signal quality. With high noise rejection of 35 dBc, the module enables fewer interference issues between IEEE 802.16 WiMAX and other radios, according to the company. The AFEM-S257 module achieves 24 dBm of WiMAX-compliant output power, while maintaining an error vector magnitude (EVM) of 2.5 percent at 16 quadrature amplitude modulation (QAM).
