Product Description
Applications
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.
ZigBee® Based Systems for
Remote Monitoring and
Control
Smart Meters for Energy
Management
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
between WiFi RX, WiFi TX and BluetoothTM RX/TX operations. The device is
provided in a 3mmx3mmx0.45mm, 16-pin QFN package. This module
meets or exceeds the front-end system requirements for and WiFi applica-
tions.
