Notes:
Some component labels may be different from the corresponding component symbol shown here.
Component values, however, are accurate as of the date of this data sheet.
PCB Recommendations:
Metal Layer 1 = RF traces + control lines. Core thickness between top RF layer and ground plane is critical.
Metal Layer 2 = Solid ground plane. No traces routing.
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.
Always use 4 layers.
