https://devzone.nordicsemi.com/f/nordic-q-a/28948/nrf52832-ant-pin-currentPer this blog, I understand that the nRF52&#39;s ANT pin must be matched to 50ohm via L1/C3 and that the antenna must be matched to 50ohm. Hence a trace with 50ohm characteristic impedance must be used between the two matching networks (if the distance betweenen-USTelligent Community 13Fri, 05 Jan 2018 08:12:02 GMThttps://devzone.nordicsemi.com/thread/114526?ContentTypeID=1Fri, 05 Jan 2018 08:12:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c9294559-5a3d-49fe-b9f4-2162b49f8766Stian R&#248;ed Hafskjold<p>You have a 4dBm (=2.5mW) and an impedance of 50ohm. Then you can just use ohms law:</p> <pre><code>I = sqrt(P/R) =~ 7mA </code></pre><div style="clear:both;"></div>
