Product Description
The RF5765 provides a complete integrated solution in a single Front End
Module (FEM) for WiFi 802.11b/g/n and
Bluetooth
®
systems. The ultra
small form factor and integrated matching greatly reduces the number of
external components and layout area in the customer application. This
simplifies the total Front End solution by reducing the bill of materials, sys-
tem footprint, and manufacturability cost. The RF5765 integrates a
2.4GHz Power Amplifier (PA), Low Noise Amplifier (LNA), power detector
coupler for improved accuracy, and some filtering for harmonic rejection.
The RF5765 is capable of receiving WiFi and
Bluetooth
®
simultaneously.
The device is provided in a 3mmx3mmx0.5mm, 16-pin package. This
module meets or exceeds the RF Front End needs of IEEE 802.11b/g/n
WiFi RF systems.
