Example of external antenna bias circuitry:
Figure 23: External antenna bias circuitry example
Be aware of max bias current in case of unwanted short on the antenna cable, since the
decoupling inductor may be damaged.
In case of LNA with 1.8V supply, VAUX/POWERMON pin can be used to supply active GNSS
