Design in Considerations
To ensure UT4B0 works normally, the following signals shall be connected correctly:
Provide reliable power supply with DC pins
Attention to 50 ohm impedance matching of circuit for ANT_IN
ANT_PWR pin is connected to +3.3~5.0V feed, and then +3.3~5.0V feed is
provided to the antenna via ANT_IN Pin
