Product Description
The RF5611 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 RF5611
integrates the LNA with bypass and the SP3T switch of a Front-End solu-
tion for WiFi and
Bluetooth
®
combination systems. The integrated match
and DC blocking capacitors on all RF Ports reduce the number of external
components, keeping cost down and utilizing minimum layout area for
implementation. The RF5611 is provided in a 2mmx2mmx0.5mm, 12-
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.
