3.8.2. Reference Design

FC64E provides three RF antenna interfaces for antenna connection. The following reference circuit
design shows an example with ANT_WIFI0. For 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.
