The RF5225 FEM is a single-chip integrated front-end module (FEM) for high-performance WLAN applications in the 2.4 GHz to 2.5 GHz ISM band. The FEM addresses the need for aggressive size reduction for a typical 802.11b/g front-end design and greatly reduces the number of components outside of the core chipset. The FEM has integrated b/g power amplifier, power detector, RX balun, and some TX filtering. It is also capable of switching between WLAN RX, WLAN TX and BTH RX/TX operations. The device is provided in a 3 mm x 3 mm x 0.45 mm, 16-pin package. This module meets or exceeds the RF front-end needs of 802.11b/g WLAN RF systems
