5.1.3. Reference Design of Main Antenna Interface

A reference design of main antenna interface is shown as below. It is recommended to reserve a π-type
matching circuit for better RF performance, and the π-type matching components (R1/C1/C2) should be
placed as close to the antenna as possible. The capacitors are not mounted by default.
