PCB Recommendations
Recommendations for 4-layer PCB:
 Metal Layer 1 = RF traces + control lines.
 Metal Layer 2 = Solid ground plane. No traces routing. Use vias to ground under the FEM as recommended in Figure 5.
 Metal Layer 3 and 4 = Control lines + VCC traces (no VCC plane).
 Pour copper on each layer connected to the ground plane. Use VCC traces in a star distribution pattern.
Recommendations for 2-layer PCB:
 Metal Layer 1 = RF traces + control lines + VCC.
 Metal Layer 2 = Solid ground plane between the transceiver and the FEM up to the antenna, no traces routing in that area. Use vias to
ground under the FEM as recommended in Figure 5.
