ZHCSJU5B February 2019 – May 2021 CC3135
PRODUCTION DATA
The CC3135 has several options for modifying the output power of the device when required. For the 2.4 GHz band it is possible to lower the overall output power at a global level using the global TX power level setting. In addition, the 2.4 GHz band allows the user to enter additional back-offs (1), per channel, region (2)and modulation rates (3), via Image creator (see the UniFlash CC31xx, CC32xx SimpleLink™ Wi-Fi® and Internet-on-a chip™ Solution ImageCreator and Programming Tool User's Guide for more details).
Figure 8-1, Figure 8-2, and Figure 8-3 show TX power and IBAT versus TX power level settings for the CC3135 device at modulations of 1 DSSS, 6 OFDM, and 54 OFDM, respectively.
In Figure 8-1, 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.
