1 1: Introduction The AirPrime MC7411 PCI Express Mini Card is a compact, lightweight, wireless modem that provides LTE, UMTS, and GNSS connectivity for M2M applications, notebook, ultrabook and tablet computers over several radio frequency bands. Accessories A hardware development kit is available for AirPrime MC-series modules.
Hardware Integration Guide Required Connectors Table 1-1 describes the connectors used to integrate the MC7411 PCI Express Mini Card into your host device. Table 1-1: Required host-module connectors a Connector type RF cables EDGE (52-pin) SIM Description • Mate with Hirose U.FL connectors (model U.
2 2: Power Power Supply The host provides power to the MC7411 through multiple power and ground pins. The host must provide safe and continuous power at all times; the module does not have an independent power supply, or protection circuits to guard against electrical issues. For detailed pinout and voltage/current requirements of this module, refer to the AirPrime MC7411 Product Technical Specification. Module Power States The module has five power states, as described in Table 2-1.
3 3: RF Specifications Supported RF Bands The module, based on Qualcomm's MDM9250 baseband processor, supports data operation on LTE and UMTS networks over the bands described in Table 3-1, with LTE carrier aggregation (CA) as described in Table 3-2 and Table 3-3.

Hardware Integration Guide RF Connections When attaching antennas to the module: • Use Hirose U.FL connectors (3 mm x 3 mm, low profile; model U.FL #CL331-0471-0-10) to attach antennas to connection points on the module. Note: To disconnect the antenna, make sure you use the Hirose U.FL connector removal tool (P/N UFL-LP-N-2(01)) to prevent damage to the module or coaxial cable assembly. • • • Match coaxial connections between the module and the antenna to 50 .
RF Specifications important—if the host device is insufficiently shielded, high levels of broadband or spurious noise can degrade the module’s performance. • Connecting cables between the module and the antenna must have 50 impedance. If the impedance of the module is mismatched, RF performance is reduced significantly. • Antenna cables should be routed, if possible, away from noise sources (switching power supplies, LCD assemblies, etc.).
Hardware Integration Guide Note: The MC7411 is based on ZIF (Zero Intermediate Frequency) technologies. When performing EMC (Electromagnetic Compatibility) tests, there are no IF (Intermediate Frequency) components from the module to consider. Interference From Other Wireless Devices Wireless devices operating inside the host device can cause interference that affects the module.
RF Specifications instances, it is necessary to employ shielding on the components of the host device (such as the main processor and parallel bus) that have the highest RF emissions. • Filter out unwanted high-order harmonic energy by using discrete filtering on low frequency lines. • Form shielding layers around high-speed clock traces by using multi-layer PCBs. • Route antenna cables away from noise sources.
