Hi,

Apologies for the trouble. Here, attaching the link once again: General PCB design guidelines for nRF52 series

Hi,

We always recommend to copy the values and placements of the components in the RF as shown in the references, as these are the ones that we have tested and we recommend. So any change in these values or placement should be tested by the customer themselves and we cannot guarantee proper working.

Also, it would be difficult to copy exactly when given the differences in substrate, the number of layers, the length of transmission lines etc. So then you can try to tune the values of the components. I would recommend you to go through this PCB Guidelines first which can help a lot.

Regards,

Priyanka
