Power and Ground Recommendations
Power and ground routing is critical to achieving optimal performance of the AirPrime AR7558 devices
when integrated into an application.
Recommendations:
Do not use a separate GND for the Antennas
Connections to GND from the AirPrime AR7558 should be flooded plane using thermal reliefs
to ensure reliable solder joints.
VBATT is recommended to be routed as a wide trace(s) directly from the 4V supply to the
LGA pad.
