nRF9160 power requirements

[MLU]

In order to develop the most effective power supply possible for the nRF9160 SIP, I need to know both the maximum current consumption of the nRF9160 and its duration.

The data sheet only specifies the maximum currents (600mA / 3..3V).

It is possible to infer the length of these peak currents from the Online Power Profiler:  Online Power Profiler for LTE 

As is mentioned in the modem current consumption spec, https://docs.nordicsemi.com/bundle/ps_nrf9160/page/_tmp/alta.nRF9160/autodita/APPLICATION.CURRENT/parameters.id_current_modem.html the max peak current is ~450mA in a TX event with very poor VSWR.

Worst case is around ~3 seconds for a TX event.

In reality, I would expect a few 10s of ms per event maximum and ~250mA peak current.

Thank you for feedback. What happens if the power supply is to weak and voltage drops?

[MLU]

will it reduce transmitter power or will there be a RESET?
