SWRZ121A February 2022 – March 2022 CC2651R3
Reduced RX sensitivity when using integrated DC/DC converter
Revision B
Radio RX sensitivity may be degraded by approximately 2dB when using the integrated DC/DC converter.
Use the internal Global LDO to supply VDDR. This will result in increased current consumption as specified in the device datasheet. When using the integrated DC/DC converter, refer to the CC13xx/CC26xx Hardware Configuration and PCB Design Considerations Application Report for more information regarding layout considerations for optimum RF performance. Please refer to CC13x1x3, CC26x1x3 SimpleLink™ Wireless MCU Technical Reference Manual for more information regarding power management capabilities.
