The QPF4551 from Qorvo is a Wi-Fi 6 (802.11ax) Front-end module that operates from 5150-5850 MHz. It consists of an integrated 5 GHz power amplifier (PA), a single-pole two throw switch (SP2T), and a bypassable low noise amplifier (LNA). The FEM delivers a Tx power of up to 27 dBm with a gain of 32 dB and a gain of 13.5 dB in Rx mode with a noise figure of 2 dB. It requires a DC supply of 5 V.
The FEM has integrated die level filtering for 2nd and 3rd harmonics, 2.4 GHz rejection for DBDC operation, and a broad range, constant slope voltage logarithmic power detector for application feedback.
The QPF4551 is available in a laminated 16-pad package that measures 2.5 x 2.5 mm and is ideal for use in access points, wireless routers, residential gateways, customer premise equipment, and Internet of Things (IoT) applications.
