5 Antenna Connection
5.1. Antenna Connectors
RG255C-GL Mini PCIe is mounted with three antenna connectors for external antenna connection: a
main antenna connector, an Rx-diversity antenna connector, and a GNSS antenna connector. And
Rx-diversity function is enabled by default. The impedance of the antenna connectors is 50 Ω.
5.2. Antenna Interfaces
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.
