https://devzone.nordicsemi.com/f/nordic-q-a/69947/thingy91-and-qm12038-power-consumptionHi, I based a new device design on the Thingy91 antenna and tuning circuitry and noticing that the current consumption of the two QM12038&#39;s negates the amazing power efficiency of the main CPU. Each QM12038 draws 80uA according to the datasheet, anden-USTelligent Community 13Tue, 29 Dec 2020 10:20:25 GMThttps://devzone.nordicsemi.com/thread/286815?ContentTypeID=1Tue, 29 Dec 2020 10:20:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bd9eeafe-fc2c-47ed-b288-5e7788c84a97&#216;yvind<p>Hi Gavin,&nbsp;</p> <p><span>Due to Christmas holidays our technical support team is lower staffed, and the response time will be longer. Also, most of our R&amp;D our out of office until January 4th. We apologize for any inconvenience this may cause.</span></p> <hr /> <p>Please note that the RF switch QM12038 is <a href="https://www.qorvo.com/products/p/QM12038">no longer recommended for new designs - ref. Qorvo QM12038 product page</a>. There are some <a href="https://devzone.nordicsemi.com/f/nordic-q-a/69065/qm12038-discontinued">alternatives discussed here</a>. Also, note that the Thingy:91 is designed to work world-wide and thus the reason for this design choice.&nbsp;<br />&nbsp;</p> [quote user=""]I&#39;m curious what is&nbsp;Nordic&#39;s baseline PSM sleep current consumption of the Thingy91, as theoretically it has to be minimally about 170uA?[/quote] <p>Yes, there is no way of shutting the RF switches down on the Thingy:91 yielding about 170µA, according to our HW designer.&nbsp;</p> <p>Kind regards,<br />Øyvind</p><div style="clear:both;"></div>
