nrf52832 chip antennahttps://devzone.nordicsemi.com/f/nordic-q-a/9208/nrf52832-chip-antennaHi, I have seen a number of nRF51822 using chip antennas through a 2450BM14E003. An example is this circuit with the pins connected as follows: ANT2 -&gt; BAL1, ANT1 -&gt; BAL2 and VDD_PA -&gt; DC. Is it possible to use a similar circuit for the nRF52832en-USTelligent Community 13Mon, 04 Apr 2016 13:43:45 GMTRE: nrf52832 chip antennahttps://devzone.nordicsemi.com/thread/33942?ContentTypeID=1Mon, 04 Apr 2016 13:43:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:536bfb9e-66b0-4aed-9f45-db54406e5ab8MartinBL<p>Updated the links now.</p><div style="clear:both;"></div>RE: nrf52832 chip antennahttps://devzone.nordicsemi.com/thread/33943?ContentTypeID=1Mon, 04 Apr 2016 12:00:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8efecd8a-3228-4ddb-862f-3ea2a766ca9eGordon<p>Hi - the links in this post no longer seem to work - is it possible to update them?

It is now single-ended with an on-chip balun and hence, it is no longer necessary with an external third party balun. We do recommend though, to use an external matching network before the chip antenna. Have a look at the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.whitepapers/dita/whitepapers/white_papers.html?cp=11">nWP017 Antenna tuning whitepaper</a>, Chapter 4.2 and 8.1 for details.</p> <p>Note that Figure 1 in the chapter &quot;<em><a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.0/radio.html?cp=1_2_0_21#concept_lhd_ygj_4r">2.4 GHz Radio (RADIO)</a></em>&quot; in the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52/dita/nrf52/chips/nrf52832.html?cp=1_2">nRF52 Product Specification</a> might be slightly misleading as it refers to ANT1 and ANT2. It is reported to the technical writers and will be altered.</p> <p>Also, if you haven&#39;t already, have a look at the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52/dita/nrf52/pdflinks/ref_layout.html?cp=1_5">nRF52 reference layouts</a> for guidance on schematics and PCB designs.</p><div style="clear:both;"></div>
