8. Power Consumption
The following power consumption data is based on a 3.3V power supply, an ambient temperature of 25°C, and is measured using an internal regulated power supply.
- All measurements were made at the antenna interface without a SAW filter.
- The emission data used is based on a 90% duty cycle, measured in a continuous emission mode.
