RFMD + TriQuint = Qorvo RFFM4554 RFFM4554 Wi-Fi Integrated Front End Module 4.9GHz to 5.925GHz Package: QFN, 16-pin, 2.3mm x 2.3mm x 0.45mm The RFFM4554 is a front end module (FEM) designed for 802.11a/n/ac applications. The integrated single-pole double throw switch and low noise amplifier with bypass greatly reduces the layout area, bill of materials and manufacturability cost in the customer application. The RFFM4554 has a unique structure where the switch to LNA path has pins so filtering can be added in the ideal path for current Wi-Fi circuit applications. The device is provided in a 2.3mm x 2.3mm x 0.45mm 16pin QFN package that meets or exceeds the power requirements of IEEE802.11a/n/ac Wi-Fi RF systems.
