I am looking to design in the M20048-1 for my system, the evaluation board has been working well. The board it is going on is a 6 layer with a solid ground on layer 2. My first question is on availability and product lifespan. Is the M20048-1 expected to be available for the foreseeable future with a decent roadmap? This appears to be the newest and recommended option but I'd like to confirm. I have no problem fitting the module on the PCB with >40mm of edge length and a solid ground underneath it on layer 2, I want to know how critical it is that on layer 1 I keep all components clear in that 40mm edge, and how far back I need to, what the overall keepout area should be, it looks like running it back into the board is not that critical, but I was using the M20057-1 and was never able to get satellite visibility, even with this type of arrangement. I know I need to keep high frequency and switching components away from the module, but I have some analog and DC circuitry that runs ~0.5" away or so. And some on the bottom of the board, there's a solid ground on layer 5 as well.
