P2
The DC blocking capacitors have to be placed at RF terminal of PC, P1 and P2.
For good RF performance, the ground terminals must be placed possibly close to ground plane
of substrate, and through holes for GND should be placed near by the pin connection.
Bypass capacitor (C4) should be placed close to terminal of VDD to reduce stripline influence of
RF characteristics.
