FCC certification

[Vikas Bhatt]

Is there a requirement to obtain separate testing or certification when using two FCC-approved RF modules on the same PCB? If so, what is the process for doing this?

Hi, 

You mean when you have two pre-certified modules, added to one pcb? 

Then a co-existing test is most likely needed, check with a test house, they know.
