3.4 Mounting information
The Figure below shows the PCB pinout of a ZigBit module. Neither via-holes nor wires are allowed on the PCB upper
layer in the area occupied by the module. As a critical requirement, RF_GND pins should be grounded via several via-
holes to be located right next to the pins thus minimizing inductance and preventing both mismatch and losses.
