Figure 15. Top Layer Routing Recommendations
Refer to Figure 9, for the bottom layer layout recommendations. On the second layer; it is
important to have a solid ground plane underneath the RF structure and to avoid any routing
directly underneath the RF. The power routing has been routed in a star formation and the
power tracks must always be routed to the decoupling capacitor first; then from the
decoupling capacitor to the pad of the CC1101.
