How do I calculate the total power consumption of my system?

The total power consumption of the radio system depends on multiple factors described below. The power consumption should be measured or simulated for each of these states to understand the expected battery life.

For systems which wake frequently to transmit or receive a packet, the total power consumption of the system will likely be dominated by active power consumption and state transition times. For systems which spend longer durations inactive, the power consumption will be dominated by the sleep mode power consumption.

1. Active mode power consumption: This is the current consumed in the active receive and transmit states of the radio


2. Sleep mode power consumption: This is the current consumed when the radio is in sleep mode with memory retained. In this state, the radio can be woken up relatively quickly without the need for the microcontroller to fully re-program it. At 10nA, the ADF7030-1 is industry leading in this mode 


3. Shutdown power consumption: In this mode power is removed from the device and the total power consumption consists of leakage current and battery self-discharge only


4. State Transition timing: This is the power consumed as the device is changing state


5. Battery Self-Discharge: This will be defined by the battery manufacturer and should be considered as part of the calculation for total system consumption
