The absolute maximum ratings in the RF input level for the nrf52832dk &amp;amp; nrf52840 preview dk are 10 dBm (see &lt;a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf52832.ps.v1.1%2Fabs_max_ratings.html&amp;amp;cp=2_1_0_4&amp;amp;anchor=abs_max_ratings"&gt;link&lt;/a&gt;). Even if you set transmission power to max, the reflected signal will never reach 10 dBm. Hope that answers your question!&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
