The QPF4216 from Qorvo is an integrated front end module (FEM) designed for Wi-Fi 6 (802.11ax) systems. It integrates a 2.4 GHz power amplifier (PA), regulator, a single pole two throw switch (SP2T), and a bypassable low noise amplifier (LNA) into a single device. This FEM also integrates a logarithmic power detector, which enables power control across the entire power spectrum. It also features integrated die level filtering for 2nd and 3rd harmonics as well as 15 dB 5 GHz rejection on the RF path for DBDC operation.
The QPF4216 provides a transmit gain of 32 dB, receive gain of 15.5 dB and has a noise figure of 1.8 dB while operating over a 5 V supply. It is available in a 5 x 3 mm 24-pin LGA package and is ideally suited for Access Points, Wireless Routers, Residential gateways, Customer Premise Equipment, and Internet of Things (IoT) applications.
