Quectel EG915U-EU - RF Design and Interfaces

LTE Standard Module Series
EG915U-EU_Hardware_Design 56 / 81
5.1.4. Reference Design
The module provides 2 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 (R1, C1, C2 and R2, C3, C4) should be placed as close to the antenna as possible.
The capacitors are not mounted by default.
