RF performance of nRF52 at 1.8V

[siliconwitch]

Hi,

I'm trying to get a general idea of how the radio will perform near the bottom end of the supply range.

Our product concept is currently designed on a system voltage of 1.8V via a switching regulator. Right now, all the radio performance data in the nRF datasheet is stated at 3VDC.

Has Nordic or anyone else done any performance analysis with a 1.8V supply?

Is there some kind of internal re-regulation for the RF components or are they simply run off the rail?

What kind of difference can be expected in current consumption?

Many thanks!

To get an idea on what the current consumption will be with the 1.8 V mode, you can use the nRF52 Online Power Profiler. The nRF52 Online Power Profiler breaks down the current consumption for BLE applications quite nicely.
