5 Antenna Interfaces
5.1. Cellular Network
5.1.1. Antenna Interfaces & Frequency Bands
The module provides Main, Rx-diversity/GNSS antenna connectors which are used to resist the fall of
signals caused by high-speed movement and multipath effect. The impedance of antenna ports is 50 Ω.

5.1.2. Antenna Tuner Control Interface*
ANTCTL [0:3] and RFFE interface are used for antenna tuner control and should be routed to an
appropriate antenna control circuit. More details about the interface will be added in the future version of
this document.
