The available connectors are:
• Main RF antenna (ANT)
• RX Diversity Antenna (DIV)
• GNSS Antenna (GPS)
Connecting cables between the module and the antenna must have an impendance of 50
Ω.
If the module impedance does not match, the RF performance is reduced significantly.
If the host device is not designed to use the module diversity or the GPS antenna,
terminate the interface with a 50Ω load.
7.3.2. Main GSM/WCDMA/LTE Antenna Requirements
The antenna for the LE910Cx-mPCIe device must meet the following requirements:
