PRECAUTIONS
P3
[1] The DC blocking capacitors have to be placed at RF terminal of P1, P2, P3 and PC.
[2] To reduce stripline influence on RF characteristics, please locate bypass capacitors (C5~C7)
[3] For good isolation, the GND terminal must be connected with the ground plane of substrate,
close to each terminal.
and through-holes for GND should be placed near by the IC.
