5G NR TDD n78 (100 MHz)

5.1.4. Reference Design of Cellular Antenna Interfaces

The module provides four 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 (a capacitor-resistor-capacitor group) should be placed as close to the antenna as
possible. The capacitors are not mounted by default.

5.2. GNSS

The module integrates the IZat™ GNSS engine (Gen 9) which supports multiple positioning and
navigation systems including GPS, GLONASS, BDS, Galileo, NavIC, QZSS, SBAS. With an embedded
LNA, the module provides greatly improved positioning accuracy.
