The WLAN8101H is a 2.4 GHz 2 x 2 MIMO RFFE for
Wi-Fi 6 applications in a 3 mm x 4 mm package.
The WLAN8101H includes two monolithic front-end ICs. Each front-end IC includes a transmit amplifier with directional coupler, a low noise receive amplifier and a transmit/receive switch with a Bluetooth channel. The power amplifier supports 3 different TX gain modes to improve power efficiency. The directional coupler improves transmit-power sensing accuracy.
WLAN8101H also includes coexistence filters for both transmit and receive channels.
The device is matched to 50 Ω and integrates harmonic and out of band filtering which minimizes the layout area in the application.
