Caution: The AirPrime AR7552 embedded modules are sensitive to Electrostatic Discharge. ESD
countermeasures and handling methods must be used when handling the AirPrime AR7552
devices.
2.3. Power and Ground Recommendations
Power and ground routing is critical to achieving optimal performance of the AirPrime AR7552 devices
when integrated into an application.
Recommendations:
 Do not use a separate GND for the Antennas
 Connections to GND from the AirPrime AR7552 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.
