Antenna Interface
CLM920_TD5 Mini PCIE module has three antenna interfaces which include a main
antenna interface, a Rx-diversity antenna interface and a GNSS antenna interface.
Diversity antenna is recommended, which used to limit the signal drop by high speed
moving or multipath fading.

3.12.2 RF Connector
The connection mode of using RF Connector is recommended.
The antenna connector must use a 50Ω characteristic impedance coaxial connector
and choose the RF cables which insertion loss as low as possible.
It is recommended to use Murata's MM9329-2700 connector.
