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
[3]For good RF performance, the GND terminal must be placed close to ground plane of substrate,
[4]Exposed pad in the bottom must be connected to ground by via holes.
influence on RF characteristics.
and through holes for GND should be placed near by the GND pin connection.
