8.6 TX Power and IBAT Versus TX Power Level Settings
, and
show TX Power and IBAT versus TX power level settings for
the CC3220MODS module at modulations of 1 DSSS, 6 OFDM, and 54 OFDM, respectively. For the
CC3220MODSF module, the IBAT current has an increase of approximately 10 mA to 15 mA depending on
the transmitted rate. The TX power level will remain the same.
In
, the area enclosed in the circle represents a significant reduction in current during transition from
TX power level 3 to level 4. In the case of lower range requirements (14-dBm output power), TI recommends
using TX power level 4 to reduce the current.
