You can submit a review request here on Devzone and we will have a look at the design and provide som feedback if we see anything of concern.

Hi Jonathan,

Thank you the speedy response. That's generally what I was presuming. I will not be locating any synchronous circuitry in these areas.

Cheers,

Chris

Hi,

Adding extra components here in the green boxes is not an issue generally. If you add something that is very noisy like a switching regulator or something similarly noisy then you might see noise bleeding in to the RF parts, but that is not a big concern for most components.

You can also add some extra via fencing around the edges as an extra measure to keep any possible disturbance away from the RF section.

Jonathan
