PRECAUTIONS

[1] The bypass capacitors should be connected to the VDD, VSS terminals as close as possible

respectively.

[2] For good RF performance, the ground terminals should be directly connected to the ground

patterns and through-holes as close as possible by using relativity wide pattern.

PCB: FR-4, t= 0.2mm

Strip width: 0.4mm
