The RF section of this wireless device 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 device. 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 CC3120MOD module.
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.
