Product Description
The RF5501 is designed specifically for high-performance WiFi applica-
tions in the 2.4 GHz to 2.5 GHz ISM band, including Personal Media Play-
ers (PMPs), digital cameras, and WiFi enabled handsets.
The RF5501 integrates the LNA with bypass and an SP3T switch of a
Front-End solution for WiFi and Bluetooth® combination systems. The
integrated input and output match reduces the number of external compo-
nents, keeping cost down and utilizing minimum layout area for implemen-
tation. The RF5501 is provided in a 2 mm x 2 mm x 0.5 mm, 12-pin QFN
package. This LNA + Switch front-end solution meets or exceeds the spec-
ification requirements of IEEE 802.11 b/g/n WiFi RF systems.
