The QPF4206B from Qorvo is a 2.4 GHz front end module (FEM) designed for Wi-Fi 802.11ax systems. The FEM consists of a 2 GHz power amplifier (PA), regulator, SPDT switch, and a bypassable low noise amplifier (LNA). The QPF4206B offers 33 dB of Tx gain and 16 dB of Rx gain with LNA noise figure of 2.1 dB. It is optimized for a 5V supply voltage that conserves power consumption while maintaining the highest linear output power and leading-edge throughput. The FEM is available in compact surface mount package that measures 3 x 3 mm and is ideal for access points, wireless routers, residential gateways and Internet of things applications.
