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.
