PRECAUTIONS
[1]The DC blocking capacitors have to be placed at RF terminal of P1, P2, P3, P4 and PC.
[2]To reduce strip line influence on RF characteristics, please locate bypass capacitors(C5)
[3]For good isolation, the GND terminal must be connected to the ground plane of substrate,
Please choose appropriate capacitance values to the application frequency.
as close as possible to each terminals.
and through-holes for GND should be placed near by the pin connection.
