Application information
Here below there are some suggestions to better implement the module in the final
application.
●
●
Keep the RF ground separate from the module supply voltage ground; the two grounds are
already connected inside the module in one point, see below a possible implementation.
Figure 9.
Avoid that traces with switching signals are routed on the motherboard below the
module. The best condition would be to have a ground plane underneath the module
Connect the supply voltage ground of the module with the other grounds present on the
motherboard in a star way.
