https://devzone.nordicsemi.com/f/nordic-q-a/51663/nrf52832-antenna-signal-tolerances-for-strong-periodical-nearby-signalsGood afternoon! We&#39;re considering an off-the-shelf nRF52832 based device for our needs. the application will likely involve two nRF5283-based devices fitted with external antenna with &gt;3 dbi gain, which is supported and supplied by the same peopleen-USTelligent Community 13Wed, 04 Sep 2019 13:57:24 GMThttps://devzone.nordicsemi.com/thread/207996?ContentTypeID=1Wed, 04 Sep 2019 13:57:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:29b5a39e-a447-42e6-b1e8-025a5264f131A_Churay<p>Thanks!</p> <p></p> <p>So hard limit is 10dBm.</p> <p>Good, but, given that both receiver and transmitter have those +3&nbsp;dBm antennas and maximum power for TX is stated to be 6dBm in the datasheet, wouldn&#39;t that end up at possibly very close to the 10&nbsp;dBm limit on the RX side (not sure what losses are for ~5cm of distance but probably not very much)?</p> <p></p> <p>does the 10&nbsp;dBm limit apply only if the receiver&#39;s radio is in RX state, or is it more of a &quot;raw electrical thing&quot; that can possibly fry the device even if it is in &quot;radio disable&quot; state?&nbsp;&nbsp;</p> <p></p> <p>P.S.:</p> <p>I&#39;ll see if our TX can &quot;punch through&quot; at lower transmit power, just in case.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/207922?ContentTypeID=1Wed, 04 Sep 2019 11:49:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c8db5ea1-8596-4c45-b346-fafd8739abb2ketiljo<p>The radio frond end is designed to handle 10 dBm on the antenna pin without physical damage. There will be some loss between the two antennas so the actual level on the&nbsp;receiver antenna pin will of course be lower than the transmit power of the other transmitter. So unless you have a PA in your system, there&#39;s no risk of permanent damage.</p><div style="clear:both;"></div>
