The requested TX power is the final output power after the gain stage.</p> <p>By default the fem TX gain is set to 22dB to support the SKY6112-11, if a FEM with a different gain is used this must be configured with the <code>tx-gain-db</code> property in the FEM devicetree node.</p> <p><a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.0.0/nrf/ug_radio_fem.html#id14">https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.0.0/nrf/ug_radio_fem.html#id14</a></p> <p>&nbsp;</p> <p>Best regards,</p> <p>Bendik</p><div style="clear:both;"></div>
