Notes:

1.

L1 and C1 are the components for input matching network. They may need to be adjusted for different PCB layout

and antenna requirements.

2.

The value of C4 depends upon the data rate and coding pattern.

3.

The optional components may be used depending upon specific application requirements, e.g. C5 can

be removed if the crystal oscillator operates at the accurate frequency.
