Antenna Interfaces

EM12-G provides a main antenna interface, an Rx-diversity antenna interface which is used to resist the
fall of signals caused by high speed movement and multipath effect, and a GNSS antenna interface. The
antenna ports have an impedance of 50Ω.

5.1. Main/Rx-diversity Antenna Interfaces

The main/Rx-diversity/GNSS antenna interfaces are shown as below.
