4 Reference Designs
In order to use the modular certification for your design, it is critical that the reference design is
correctly followed. This section describes the details of using a PCB that is a 4-layer stack up.
The full 4-layer Chip Antenna PCB reference design is shown in Figure 1, Schematic Figure 2, and
Bill of Materials Table 2. The full 4-layer U.FL (external antenna) PCB reference design is shown
in Figure 3 , Schematic Figure 4, and Bill of Materials Table 3.
It is not required to replicate the entire design, but what is required are the circuitry and layout
as it pertains to the antenna configuration being used in your design as shown in
