RF5540 4.9GHz to 5.85GHz Switch and LNA Front End Solution RF5540 4.9GHz TO 5.85GHz SWITCH AND LNA FRONT END SOLUTION Package: QFN, 12-Pin, 2.0mmx2.0mmx0.5mm 12 11 10 GND NC Features 1 9 Single Supply Voltage 2.7V to 4.8V Integrated 5GHz LNA With 2 8 ANT RX Out Bypass and SPDT Applications 3 7 GND NC IEEE802.11a WiFi Applications Consumer Electronics 4 5 6 Mobile Devices Gaming General Purpose Switch and LNA Functional Block Diagram Solution for 4.9GHz to 5.85GHz Frequency Range Product Description The RF5540 is designed specifically for high-performance WiFi applications in the 5GHz ISM band. This module integrates the LNA with bypass and an SPDT switch of a Front End solution. The integrated input and output match reduces the number of external components keeping cost down and utilizing minimum layout area for implementation. The RF5540 is provided in a 2mmx2mmx0.5mm, 12-pin QFN package. This LNA + Switch front-end solution meets or exceeds the specification requirements of IEEE 802.11a RF systems.
