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 Features applications. The integrated single-pole double throw switch and low 13.5dB LNA Gain noise amplifier with bypass greatly reduces the layout area, bill of materials and manufacturability cost in the customer application. The 5dB Bypass Loss RFFM4554 has a unique structure where the switch to LNA path has pins 1.7dB Noise Figure so filtering can be added in the ideal path for current Wi-Fi circuit TX to ANT path loss of 0.5dB applications. The device is provided in a 2.3mm x 2.3mm x 0.45mm 16- Max Power at TX Input of 30dBm pin QFN package that meets or exceeds the power requirements of 2.4GHz Rejection IEEE802.11a/n/ac Wi-Fi RF systems.
