https://devzone.nordicsemi.com/f/nordic-q-a/18811/separate-rx-and-tx-antennaIs it possible to connected two separated antennas (single ended), one for RX and another for TX communications to the receiver and transmitter of the NRF51 or NRF52? Thanks!en-USTelligent Community 13Fri, 06 Jan 2017 16:21:22 GMThttps://devzone.nordicsemi.com/thread/72645?ContentTypeID=1Fri, 06 Jan 2017 16:21:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e85890f9-87ea-44c9-b520-57e7eb4542b8AlHe<p>Thank&#39;s for your reply!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/72643?ContentTypeID=1Fri, 06 Jan 2017 11:40:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6c4c957b-13ea-4f70-a788-915786d4023eSigurd<p>What is the use-case for this? This would increase the complexity, the space needed on the pcb, power-usage and the cost.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/72644?ContentTypeID=1Fri, 06 Jan 2017 11:28:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:565a6ca4-d4ae-4746-b382-90171650c775Sigurd<p>Hi,</p> <p>Yes, this should be possible by using a RF switch/antenna diversity switch. You can then use <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s132.sds/dita/softdevices/s130/radio_notif/radio_notif_palna.html?resultof=%22%50%6f%77%65%72%22%20%22%70%6f%77%65%72%22%20%22%41%6d%70%6c%69%66%69%65%72%22%20%22%61%6d%70%6c%69%66%69%22%20%22%4c%6f%77%22%20%22%6c%6f%77%22%20%22%4e%6f%69%73%65%22%20%22%6e%6f%69%73%22%20%22%63%6f%6e%74%72%6f%6c%22%20%22%63%6f%6e%66%69%67%75%72%61%74%69%6f%6e%22%20%22%63%6f%6e%66%69%67%75%72%22%20%22%28%50%41%2f%4c%4e%41%29%22%20">PA/LNA control</a> to tell when a TX or RX radio event is coming up, in order to switch between the TX/RX antennas.</p> <p>Using two antennas for TX/RX is not a normal use-case, so we don’t have any reference design for this.</p><div style="clear:both;"></div>
