Wi-Fi FEM boasts optional external filtering

The QPF4216B FEM delivers higher power and better throughput in Wi-Fi 802.11ax systems than competing devices.

Integrated matching minimises layout area and the device is pinned out so external filtering can be added in the optimal position.

Performance features include 22 dBm Pout (at -43 dB DEVM) and 26 dBm Pout (at MCSO HT20). Transmit gain is 32 dB while receive noise figure is 1.8 dB. 5 GHz signals are filtered with 15 dB rejection.

The QPF4216B integrates RF and DC power detection in a 5 x 3 mm laminate package.
