RF5745

2.4GHz TO 2.5GHz, 802.11b/g/n

SINGLE-BAND FRONT END MODULE

The RF5745 is a single-chip integrated front-end module (FEM) for high-

performance ZigBee® and other WiFi applications in the 2.4GHz to

2.5GHz ISM band. The FEM addresses the need for aggressive size reduc-

tion for a typical IEEE802.15.4 and IEEE802.11b/g systems.

The RF5745 greatly reduces the number of external components by inte-

grating all matching networks. The FEM has an integrated power amplifier,

LNA, power detector, and some TX filtering. It is also capable of switching

provided in a 3mmx3mmx0.45mm, 16-pin QFN package. This module

meets or exceeds the front-end system requirements for and WiFi applica-

tions.
