https://devzone.nordicsemi.com/f/nordic-q-a/37713/maximum-allowed-tx-powerI&#39;m developing a product with the nRF52840 using nRF_SDK 15.0.0 and s140 v6.1.0.

Are there any regulatory limitsen-USTelligent Community 13Wed, 22 Aug 2018 10:58:55 GMThttps://devzone.nordicsemi.com/thread/145313?ContentTypeID=1Wed, 22 Aug 2018 10:58:55 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9655952b-e4a5-4bbd-97f2-435eddb3fc6aketiljo<p>Hi Øyvind</p> <p>The output power is limited to 10 dBm / 1 MHz in Europe. This is EIRP, so measured radiated.&nbsp;</p> <p>You should be able to use 8 dBm here.</p> <p>&nbsp;</p> <p>best regards,</p> <p>Ketil Aas-Johansen</p><div style="clear:both;"></div>
