PRECAUTIONS
[1] The DC blocking capacitors have to be placed at RF terminal of P1, P2 and PC.
Please choose appropriate capacitance values to the application frequency.
[2]To reduce stlipline influence on RF characteristics, please locate bypass
capacitors (C4, C5) close to each terminals.
[3]For good isolation, the GND terminal (2nd pin) must be placed possibly close to
ground plane of substrate, and through holes for GND should be placed near by
the pin connection.
