https://devzone.nordicsemi.com/f/nordic-q-a/57976/increasing-nrf24l01-transmitting-power-to-18-dbmHello Sir, We are using NRF24L01+PA+LNA SMA Antenna for transmission purpose using arduino using RH_NRF24.h library. It is been set to 0dBm transitting power by default. We need to communicate at higher range values so we need to increase its transmittingen-USTelligent Community 13Wed, 19 Feb 2020 08:04:01 GMThttps://devzone.nordicsemi.com/thread/235070?ContentTypeID=1Wed, 19 Feb 2020 08:04:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:765bbe2d-c712-4cc8-bc6f-cfba2a7e8e93H&#229;kon Alseth<p>Hi,</p> <p>&nbsp;</p> <p>The nRF24L01+ can output up to 0 dBm, and it is your external PA/LNA that needs to be controlled in order to set the given amplification.</p> <p>I would recommend that you check up on how your PA/LNA needs to be controlled, and see how it is connected by checking with the module vendor. Normally the PA part is controlled via the VDD_PA pin, as this pin goes high when the radio is transmitting.</p> <p>&nbsp;</p> <p>Kind regards,</p> <p>Håkon</p><div style="clear:both;"></div>
