Energy Efficient WiFi 6 FEM Integrates BAW Filtering

RFMW announces design and sales support for a WiFi 6 (802.11ax) front end module (FEM). The Qorvo QPF7219 optimizes an internal power amplifier for 5V operation while maintaining linear output power and leading-edge throughput across WiFi channels 1 through 11. Integrating a 2.4 GHz power amplifier (PA), regulator, single-pole two-throw switch (SP2T), bypassable low noise amplifier (LNA), and power detector into a small 5 x 3 mm package, it also contains DIE level filtering for harmonics and 5 GHz rejection. Designed for access points, wireless routers, residential gateways and CPEs in the 2402 to 2472 MHz frequency range, the QPF7219 offers 31 dB of Tx gain and 15.5 dB of Rx gain with LNA noise figure of 2 dB.
