3.10.2. Reference Design of RF Antenna Interfaces

FG50V provides three RF antenna interfaces for antenna connection. The following reference circuit
design shows an example with ANT_WIFI0. For the other RF antenna interfaces, the reference design is
the same.
It is recommended to reserve a π-type matching circuit for better RF performance, and the π-type
matching components (C1, C2, R1) should be placed as close to the antenna as possible. The capacitors
are not mounted by default.
