1 1: Introduction The Sierra Wireless EM7511 Embedded Module is an M.2 module that provides LTE, UMTS, and GNSS connectivity for notebook, ultrabook, tablet computers, and M2M applications over several radio frequency bands. Accessories A hardware development kit is available for AirPrime M.2 modules.
2 2: Power Power Supply The host provides power to the EM7511 through multiple power and ground pins. The host must provide safe and continuous power (via battery or a regulated power supply) 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, see the AirPrime EM7511 Product Technical Specification.
Power Disconnected Rev Apr.18 • Host keeps module powered off by asserting Full_Card_Power_Off# (signal pulled low or left floating) • Module draws minimal current • Host power source is disconnected from the module and all voltages associated with the module are at 0 V.
3 3: RF Specifications The EM7511 operates on the frequency bands listed below.

Product Technical Specification Antenna and Cabling When selecting the antenna and cable, it is critical to RF performance to match antenna gain and cable loss. Choosing the Correct Antenna and Cabling When matching antennas and cabling: • The antenna (and associated circuitry) should have a nominal impedance of 50 with a return loss of better than 10 dB across each frequency band of operation. • The system gain value affects both radiated power and regulatory (FCC, IC, CE, etc.) test results.
RF Specifications Ground Connection When connecting the module to system ground: • Prevent noise leakage by establishing a very good ground connection to the module through the host connector. • Connect to system ground using the module’s mounting hole. • Minimize ground noise leakage into the RF. Depending on the host board design, noise could potentially be coupled to the module from the host board.
Product Technical Specification Proximity of host electronics to the antenna in wireless devices can contribute to decreased Rx performance. Components that are most likely to cause this include: • Microprocessor and memory • Display panel and display drivers • Switching-mode power supplies Device-generated RF Interference The module can cause interference with other devices. Wireless devices such as AirPrime embedded modules transmit in bursts (pulse transients) for set durations (RF burst frequencies).
RF Specifications To determine the extent of any receiver performance desensitization due to selfgenerated noise in the host device, over-the-air (OTA) or radiated testing is required. This testing can be performed by Sierra Wireless or you can use your own OTA test chamber for in-house testing. Rev Apr.
