Qorvo's RF5521 is designed specifically for high-performance Wi-Fi applications in the 2.4GHz to 2.5GHz ISM band, including Personal Media Players (PMPs), digital cameras, and Wi-Fi enabled handsets.The RF5521 integrates the LNA with bypass and an SP3T switch of a front end solution for Wi-Fi and Bluetooth® combination systems. The integrated input and output match reduces the number of external components, keeping cost down and utilizing minimum layout area for implementation. The RF5521 is provided in an ultra small 1.75mm x 1.75mm x 0.5mm 10-pin QFN package. This LNA+Switch front-end solution meets or exceeds the specification requirements of IEEE 802.11 b/g/n Wi-Fi RF systems.
