Quectel EC200A Series

LTE Standard Module Series
5.1.4. Reference Design
The module provides two RF antenna interfaces for antenna connection.
It is recommended to reserve a π-type matching circuit for better RF performance, and the π-type
matching components (C1, R1, C2 and C3, R2, C4) should be placed as close to the antenna as possible.
The capacitors are not mounted by default.
