RF Antenna Connector | Huawei ME909 specification

HUAWEI ME909 Series Mini PCIe Module
Hardware Guide	Description of the Application Interfaces

Figure 3-10Circuit diagram of the interface of the PCM (ME909 module is used as PCM master)

PCM_SYNC: Output when PCM is in master mode;

PCM_CLK: Output when PCM is in master mode;

The PCM function of ME909 only supports master mode;

It is recommended that a TVS be used on the related interface, to prevent electrostatic discharge and protect integrated circuit (IC) components.

3.12RF Antenna Connector

The ME909 module provides three antenna connectors (MAIN, GPS and AUX) for connecting the external antennas.
