FCC certification of our product with nRF5340 SoC

[simbu]

Is the nRF 5340 already FCC Pre-Certified  ?

When we integrate the nRF5340 SoC within our product, should we need to get our product certified by FCC ? is there any difference with this certification approach for using inbuild antenna or external antenna ?

Hi Simbu, 
As far as I know the FCC certification has to be done on the actual end device. You would need to get your product to be certified by FCC. This is regardless which antenna you use. I'm not so sure what you meant by inbuild antenna, did you mean PCB antenna ?
My suggestion is to contact a testhouse that can help you with FCC certification testing. 
We can help you to check your design for antenna tunning, schematic and layout review. Here are some extra material maybe useful for you :
