1.2.3 Layout - Layer 2

Figure 1-8 shows the second layer of the 4-layer reference design. This layer is mainly a GND layer. It is important to have a solid ground plane underneath the complete RF section and to avoid any routing directly underneath the RF section. The reference design [6] has a thickness of 175 um between layer 1 and layer 2. This is the main parameter in the FR4 PCB stack-up that should be kept similar when copying the reference design.
