详细描述
The RF5725 is a single-chip integrated front end module (FEM) for high performance WiFi applications in the 2.4GHz to 2.5GHz ISM band. This FEM greatly reduces the number of external components minimizing footprint and assembly cost of the overall 802.11b/g solution. The RF5725 has an integrated b/g power amplifier LNA a Coupler Power detector and Tx filtering. It also is capable of switching between WiFi Rx WiFi Tx and BTH Rx/Tx operations. This device is manufactured using GaAs HBT and pHEMT processes on a 3mm x 3mm x 0.5mm 16-pin QFN package. This module meets or exceeds the RF front end needs of 802.11b/g WiFi RF systems.
