RF5521 3.3V, SWITCH AND LNA FRONT END MODULE Package Style: QFN, 10-pin, 1.75mmx1.75mmx0.5mm C BT BT 10 9 ANT 1 8 Vdd Features Single Supply Voltage 3.0V to 4.5V Integrated SP3T Switch and C RX RX Out 2 7 LNA with Bypass Typical gain is 12dB and 2.0dB NF in RX Mode Pin-to- Pin C TX 3 6 LNA EN Applications 4 5 IEEE802.11b/g/n WiFi Appli- cations TX in NC Portable Battery-Powered Equipment Functional Block Diagram WiFi/Bluetooth 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.
