Integrated WiFi 6 FEM allows Flexible Filtering

RFMW announces design and sales support for a WiFi 6 (802.11ax) front end module (FEM). The energy efficient Qorvo QPF4288 integrates a 2.4 GHz power amplifier (PA), regulator, SP2T switch, bypassable low noise amplifier (LNA) and coupler into a single device. Optimizing the internal PA for 5V operation while maintaining linear output power and leading-edge throughput, the QPF4288 offers 33 dB of transmit gain and 15.5 dB receive gain with 1.7 dB noise figure. The receive path is pinned out so external filtering can be added in the optimal position while filtering for 2nd and 3rd harmonics as well as 5 GHz rejection for DBDC operation are integrated at the die level. Housed in a 5 x 3 mm laminate package.
