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 foot-
print 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 3mmx3mmx0.5mm 16-pin QFN package. This
module meets or exceeds the RF front-end needs of 802.11b/g WiFi RF
systems.
