The QM42391 is a WLAN 2.4 GHz dual FEM consisting of two
2.4 GHz multi-mode PA die with coupler and two LNA +
Switches.
The QM42391 is an 802.11ax front-end module in an ultra- small
footprint. The front-end module supports three TX bias modes:
high gain + high linearity, high gain + increased efficiency, low
gain + increased efficiency. The QM42391 also has BT high
power and BT low power modes. The architecture and interface
are optimized for next generation WLA
