RF Specifications

Appropriate antenna type and design should be used with matched antenna parameters according to
specific application. It is required to perform a comprehensive functional test for the RF design before
mass production of terminal products. The entire content of this chapter is provided for illustration only.
Analysis, evaluation and determination are still necessary when designing target products.
The module provides one main antenna interface, one Rx-diversity antenna interface, two MIMO antenna
interfaces, and one GNSS antenna interface. They are used to resist the fall of signals caused by
high-speed movement and multipath effect. The impedance of antenna ports is 50 Ω.
