How does the nrf24l01 do during tx setting time?https://devzone.nordicsemi.com/f/nordic-q-a/51895/how-does-the-nrf24l01-do-during-tx-setting-timeHi all, We use a kind of widely used nrf24l01 module in our product developement.It use the nodic&#39;s reference design of nrf24l01 with an external pa/lna.TXEN and RXEN of the external PA/LNA is respectively connect to the VDD_PA and CE of nrf24l01.I brouseen-USTelligent Community 13Mon, 09 Sep 2019 12:16:39 GMTRE: How does the nrf24l01 do during tx setting time?https://devzone.nordicsemi.com/thread/208676?ContentTypeID=1Mon, 09 Sep 2019 12:16:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:961a458a-cc1b-4eb8-b377-1e3864a422faovrebekk<p>Hi</p> <p>Enabling the PA will affect the PLL frequency temporarily, and it is necessary to run the PA and the PLL together for a short time before sending the packet to make sure that the PLL is stable once you start packet transmission.&nbsp;</p> <p>The PA will run at limited output power during this stage, but there might be some output on the antenna, yes.&nbsp;</p> <p>Essentially this period is essential to ensure that the frequency and level of the radio signal is stable once the packet transmission starts.&nbsp;</p> <p>Best regards<br />Torbjørn</p><div style="clear:both;"></div>
