Figure 43 WiFI_BT antenna interface connection circuit
In the figure, R301, C301, and C302 are antenna matching devices, and the specific component values
can be determined after the antenna factory debugs the antenna. Among them, R301 defaults to 0R,
C301 and C302 do not paste by default.
If there are fewer components between the antenna and the module output, or if the RF test head is not
needed in the design, the antenna matching circuit can be simplified as shown below:
