External grounding
External grounding and care is the integrators responsibility with the Nemo2 module for
functionality and RF integration with an antenna or antenna connector. A solid ground
reference is needed in particular to the Rf signal path to the terminating component
such as an antenna or antenna connector.
The Nemo2 evaluation board with a SMA connector and the SMA di-pole antenna took
great consideration of the RF path and its reference to ground. See below on the
layout of the top layer where the RF path resides and ground fill as a reference to the
RF signal.
