928 MHz band.
Typical Transmitter Application
Notes:
1.
This matching component is required only for antennas that are not 
50 ohms. It is typically a chip inductor to match to stub antennas 
shorter than  wavelength. For very low radiated field-strength appli-
cations, a resistor can also be used.
For ESD protection.
