But, we have problem the transmitter frequency for the certification. This problem is frequency offset of ANT pin of the nRF52832(2.4 GHz). I saw it on the NORDICen-USTelligent Community 13Wed, 27 May 2020 02:13:21 GMThttps://devzone.nordicsemi.com/thread/251807?ContentTypeID=1Wed, 27 May 2020 02:13:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:63280fd2-8a3a-4255-aa14-38b69697285dDaeho<p>Thank you, Simon. I will test it.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/251721?ContentTypeID=1Tue, 26 May 2020 12:42:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:04748c20-a66c-45e7-9bae-5a8273968ad9Simonr<p>Hi</p> <p>Yes, the capacitor values of the 32MHz crystal in your design will affect the transmitter on your device. The worst case is that the radio won&#39;t transmit at all. Even small changes to the CL values might cause issues in radio efficiency and accuracy, so you should follow this rather strictly when designing your circuit. C<span>rystal load capacitors are determined by C1 = C2 = 2*&nbsp;</span><span>C_L</span><span>&nbsp;- 4 pF, where&nbsp;</span><span>C_L</span><span>&nbsp;is specific for the crystal. The load capacitance (C_L) should be stated in the crystal&#39;s datasheet, so you should be able to determine the correct capacitor values from there.</span></p> <p><span>Best regards,</span></p> <p><span>Simon</span></p><div style="clear:both;"></div>
