Schematic design guidelines:

Components in the above figures must be capacitors, inductors, and 0 Ω resistors. Place these
RLC components as close to the antenna interface as possible.

Add ESD protection if the antenna might generate static electricity. ESD components with ultra-
low junction capacitance can be used. It is recommended to use a TVS diode with a junction
