Rev 4.0.1 May.11 Proprietary and Confidential 711: IntroductionSierra Wireless’ AirPrime Intelligent Embedded Modules form the radio component for the products in which they are embedded.The AirPrime MC7700 is available for use on LTE, WCDMA and GSM networks.Note: An understanding of network technology, and experience in integrating hardware components into electronic equipment is assumed.Purpose of this guideThis guide addresses issues that affect the integration of AirPrime embedded modules into host products, and includes design recommendations for the host products.The Universal Development KitSierra Wireless manufactures a Universal Development Kit (UDK) that facilitates all phases of the integration process.This kit is a hardware development platform that is designed to support the AirPrime embedded modules. It contains the hardware components that are typically necessary for evaluating and developing with the module, including:•Development board•Cables•Antennas•Other accessoriesFor instructions on setting up the UDK, see PCI Express Mini Card Dev Kit Quick Start Guide (Document 2130705).Required connectorsNote: Contact vendors before choosing your connectors—the numbers included here are for reference only. Choose connectors that are appro-priate to your design.When integrating AirPrime embedded modules into your host device, you need the following connector types:•RF cables that mate with Hirose U.FL connectors (model U.FL #CL331-0471-0-10). Modules include two or three connector jacks depending on module support for diversity and GPS functionality.•Industry-standard mating connector for 52-pin EDGE—some manufacturers include Tyco, Foxconn, and Molex. For example, the connector used on the Mini Card Dev Kit board is a Molex 67910-0001.•Industry-standard USIM connector—the actual connector you use depends on how your device exposes the USIM socket. For example, the USIM connector used on the Mini Card Dev Kit board is an ITT CCM03-3518.

Rev 4.0.1 May.11 Proprietary and Confidential 922: Power InterfaceOverview of operationAirPrime embedded modules are designed to use a 3.3V (nominal) power supply provided by the host. It is the host’s responsibility to provide safe and continuous power to the module at all times; the module does NOT have an independent power supply, or protection circuits to guard against electrical issues.The module’s power state is controlled by the host’s assertion/deassertion of W_Disable#. The module also monitors its supply voltage and requests shutdown if the supply is insufficient.Power signalsThe module must be connected to a 3.3V power supply, as described in PCI Express Mini Card Electromechanical Specification Revision 1.1.For detailed pinout and voltage/current requirements of these modules, see the Product Technical Specification Document for your AirPrime embedded module.Electrostatic discharge (ESD)You are responsible for ensuring that the host has adequate ESD protection on digital circuits and antenna ports as described by the following specifications:•(Operational) RF port (antenna launch and RF connector): IEC-61000-4-2—Level (Electrostatic Discharge Immunity Test)•(Non-operational) Host connector interface: JESD22-A114-B +/-1kV Human Body Model and JESD22-C101 +/- 125 V Charged Device ModelThis guide provides specific recommendations where needed, however, the level of protection required depends on your application.Note: ESD protection is highly recommended for the USIM connector at the point where the contacts are exposed, and for any other signals from the host interface that would be subjected to ESD by the user of the product.

AirPrime MC7700 Hardware Integration Guide12 Proprietary and Confidential 2130114RF connectionWhen attaching an antenna to 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.•Use a Hirose U.FL connector (model U.FL #CL331-0471-0-10) to attach an antenna to a connection point on the module.•Match coaxial connections between the module and the antenna to 50 •Minimize RF cable losses to the antenna; the recommended maximum cable loss for antenna cabling is 0.5 dB.•To ensure best thermal performance, if possible use the mounting holes to attach (ground) the device to the main PCB ground or a metal chassis.Note: If the antenna connection is shorted or open, the modem will not sustain permanent damage.Ground connectionWhen 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 two mounting holes at the top of the module.•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. This is mainly an issue for host designs that have signals traveling along the length of the module, or circuitry operating at both ends of the module interconnects.ShieldingThe module is fully shielded to protect against EMI and must not be removed.Antenna and cablingWhen selecting the antenna and cable, it is critical to RF performance to match antenna gain and cable loss.Choosing the correct antenna and cablingConsider the following points for proper matching of 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 IntegrationRev 4.0.1 May.11 Proprietary and Confidential 13Developing custom antennasConsider the following points when developing custom-designed antennas:•A skilled RF engineer should do the development to ensure that the RF performance is maintained.•Identify the bands that need to be supportedDetermining the antenna’s locationConsider the following points when deciding where to put the antenna:•Antenna location may affect RF performance. Although the module is shielded to prevent interference in most applications, the placement of the antenna is still very important—if the host device is insufficiently shielded, high levels of broadband or spurious noise can degrade the module’s perfor-mance.•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.). If the cables are near the noise sources, the noise may be coupled into the RF cable and into the antenna.Interference and sensitivityNote: The MC7700 is based on ZIF (Zero Inter-mediate Frequency) technologies. When performing EMC (Electro-magnetic Compatibility) tests, there are no IF (Intermediate Frequency) components from the module to consider.Several sources of interference can affect the RF performance of the module (RF desense). Common sources include power supply noise and device-generated RF.RF desense can be addressed through a combination of mitigation techniques and radiated sensitivity measurement.Power supply noiseNoise in the power supply can lead to noise in the RF signal. The power supply ripple limit for the module is no more than 200 mVp-p 1 Hz to 100 kHz. This limit includes voltage ripple due to transmitter burst activity.Interference from other wireless devicesWireless devices operating inside the host device can cause interference that affects the module.To determine the most suitable locations for antennas on your host device, evaluate each wireless device’s radio system, considering the following:•Any harmonics, sub-harmonics, or cross-products of signals generated by wireless devices that fall in the module’s Rx range may cause spurious response, resulting in decreased Rx performance.

AirPrime MC7700 Hardware Integration Guide14 Proprietary and Confidential 2130114•The Tx power and corresponding broadband noise of other wireless devices may overload or increase the noise floor of the module’s receiver, resulting in Rx desense.The severity of this interference depends on the closeness of the other antennas to the module’s antenna. To determine suitable locations for each wireless device’s antenna, thoroughly evaluate your host device’s design.Host-generated RF interferenceAll electronic computing devices generate RF interference that can negatively affect the receive sensitivity of the module.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 suppliesDevice-generated RF interferenceThe 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). Hearing aids and speakers convert these burst frequencies into audible frequencies, resulting in audible noise.
