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!
