The QPF4506 from Qorvo is a Wi-Fi 802.11ax Front-end module that operates from 5150–5925 MHz. The FEM consists of an integrated 5 GHz power amplifier (PA), a regulator, a single-pole two throw switch (SP2T), and a bypassable low noise amplifier (LNA). The receive path has integrated die level filtering for 2nd and 3rd harmonics and 2.4 GHz rejection for DBDC operation. It has an integrated logarithmic DC power detector power control to lower powers and calibration against a constant slope.
The QPF4506 delivers up to 25 dBm of Tx power with a gain of 30 dB. In Rx mode it provides a gain of 13.5 dB with a noise figure of 1.7 dB. It requires a DC supply of 5 V. This FEM is available in a laminated package that measures 3 x 3 mm and is ideal for access points, wireless routers, residential gateways, customer premise equipment and Internet of Things applications.
