PRECAUTIONS
P5
- 6 -
[1] The DC blocking capacitors should be placed at RF terminal of P1, P2, P3, P4, P5 and PC.
[2] The bypass capacitor (C7) should be placed as close as possible to VDD terminal.
[3] For good RF performance, all GND terminals are should be connected to PCB ground plane.
Please choose appropriate capacitance values to the application frequency.
