PRECATIONS
[1] For good RF performance, the ground terminals should be directly connected to the ground patterns
[2] Please connect exposed GND PADs (bottom side of IC) to PCB GND using through holes.
[3] To reduce microstrip line influence on RF characteristics, please locate bypass capacitors (C11) close
and the through-holes as close as possible by using relatively wide pattern.
