Figure below shows recommended land pattern. Red circles indicate Thermal/RFGND via’s. Recommended size
is 0.300-0.350mm with a pitch of 1mm. The recommended minimum number of via’s are 9 and they should be
directly connected to ground plane providing the best RF ground and thermal performance. For best yield plugged
or open via’s should be used.
