The QPF4578 from Qorvo is a fully integrated Wi-Fi Front-End Module designed for Wi-Fi 802.11a/n/ac/ax systems. The module provides a transmit gain of 31 dB while operating over a supply of 3.3 V. It integrates a 5 GHz power amplifier (PA), single pole two throw switch (SP2T) and bypassable low noise amplifier (LNA) into a single device. There are two options for power detect, a DC power detector which has voltage output and an RF power detector with an RF output from a directional coupler. The QPF4578 integrated die level filtering also includes 2nd and 3rd harmonics and 2.4 GHz rejection for dual-band dual-concurrent operation. It is available in a 5 x 3 mm QFN package and is ideal for wireless routers, IoT, access points and residential gateway applications.
