About the VDDPA pinhttps://devzone.nordicsemi.com/f/nordic-q-a/1337/about-the-vddpa-pinHi Could I use 3.3V to the C3 capacity in the application example,datasheet?That is to say,C3 doesn&#39;t connect to VDDPA pin and 3.3V connect to the C3.I found that it is better for the distance and communication quality even it is in a complex environmenten-USTelligent Community 13Tue, 14 Jan 2014 11:04:16 GMTRE: About the VDDPA pinhttps://devzone.nordicsemi.com/thread/6095?ContentTypeID=1Tue, 14 Jan 2014 11:04:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:83e5947b-032b-4d3d-a8c9-cccf9a3d58f7Hung Bui<p>Hi Angela,</p> <p>The normal output on VDD_PA is 1.6V. So it&#39;s not recommended to over-voltage on C3 (that will over-voltage ANT pins). Furthermore, VDD_PA is only active when the radio is active. This way, the chip can saves power consumption. If you supply C3 with 3.3V constantly you may experience higher current consumption.</p><div style="clear:both;"></div>
