The RF section of this wireless module gets top priority in terms of layout. It is very important for the RF section to be laid out correctly to ensure optimum performance from the module. A poor layout can cause low-output power, EVM degradation, sensitivity degradation, and mask violations.
Figure 10-2 shows the RF placement and routing of the CC3220MODx module with external antenna.
Follow these RF layout recommendations for the CC320MODx device:
For optimal RF performance, ensure the copper cut out on the top layer under the RF-BG pin (pin 31) is as shown in Figure 10-3.
