ZigBit™ 2.4 GHz Wireless Modules 3-15
8226C–MCU Wireless–09/10
3.4 Mounting Information
The below diagrams show the PCB layout recommended for ZigBit module. Neither via-holes nor wires
are allowed on the PCB upper layer in area occupied by the module. As a critical requirement, RF_GND
pins should be grounded via several holes to be located right next to the pins thus minimizing inductance
and preventing both mismatch and losses.
