Product Description

Combination Devices

The RF5521 is designed specifically for high-performance WiFi applica-

tions in the 2.4GHz to 2.5GHz ISM band, including Personal Media Play-

ers (PMPs), digital cameras, and WiFi enabled handsets.

The RF5521 integrates the LNA with bypass and an SP3T switch of a

Front-End solution for WiFi and Bluetooth^®combination systems. The inte-

grated input and output match reduces the number of external compo-

nents, keeping cost down and utilizing minimum layout area for

implementation. The RF5521 is provided in an ultra small

1.75 mmx1.75mmx0.5mm 10-pin QFN package. This LNA+Switch front-

end solution meets or exceeds the specification requirements of IEEE

802.11 b/g/n WiFi RF systems.
