The scenario
An engineer is designing a wearable GPS tracker and needs to integrate a GNSS module with power management and antenna circuitry.
What is in this drawing
Read the decisions behind it.
01
Use a 3.3V supply with decoupling capacitors.
02
Include a backup battery to maintain ephemeris data.
03
Add a series capacitor and 50-ohm termination for antenna matching.
When designing battery-powered GNSS devices that require low power and small footprint.
