QPF8248 wi - fi front end module advance d advanced data sheet rev c 20161219 | subject to change without notice 1 of 7 www.qorvo.com product overview the qorvo ? QPF8248 is an integrated front end module (fem) designed for wi - fi 802.11a/n/ac systems. the compact form factor and integrated matching minimizes layout area in the application. performance is focused on a b a lance of efficiency versus linear power that increas es the range and throughput of connections. control ines are reduced to a two pin scheme . integrated die level filtering for 2nd and 3rd harmonics as well as 5 ghz rejection for dbdc operation are included . the QPF8248 integrates a 2.4 ghz power amplifi er (pa), single pole three throw switch (sp 3 t) and low noise amplifier (lna) into a single device . functional block diagram top view 16 pin 2. 3 x 2. 3 mm laminate package key features ? 2412 ?
