5.2.4. Reference Design
The module provides main antenna and diversity antenna interfaces for cellular antenna connection.
It is recommended to reserve a π-type matching circuit for better RF performance. The π-type matching
components (R1, C1, C2 and R2, C3, C4) should be placed as close to the antenna as possible. The
capacitors are not mounted by default.
0 Ω is mounted on R1 and R2.
