PRECAUTIONS
[1]The DC blocking capacitors have to be placed at RF terminal of RX, TX, ANT1 and ANT2.
[2] Please locate bypass capacitors (C5,C6) close to appropriate terminals to reduce stripline
influence on RF characteristics.
[3]For good RF performance, the GND terminal must be placed close to ground plane of substrate,
and through holes for GND should be placed near by the GND pin connection.
[4]Exposed pad in the bottom must be connected to ground by via holes.
