Reference Layout about BLE (nRF52840 & nRF52832)

[Webster Yang]

Dear Nordic Teams : 

I find the layout guideline shows the C3 return path for filtering the harmonic.

The GND pin is connected to the IC's system ground directly. Do I need to separate the pin from IC's GND to prevent the noise coupling?

Actually I find the situation on the DK, so I want to check the status on DK. Could you help to confirm the situation what I mention above?

Can you share your measurement and how you have measured? What version is this of nRF52-DK?
