Hardware Integration Guide12 Proprietary and Confidential - Contents subject to change 4117682RF ConnectionsWhen attaching antennas to the module:•Use RF plug connectors that are compatible with the following RF receptacle connectors: Foxconn (KK12011-02-7H), Longwell (911-002-0006R), Speedtech (C87P101-00001-H), Murata (MM4829-2702RA4 (HSC)), IPEX (20449-001E (MHF4)).•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, use the mounting hole (if possible) to attach (ground) the device to a metal chassis.Note: If the antenna connection is shorted or open, the modem will not sustain permanent damage.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 CablingWhen 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.Table 3-3: GNSS Frequency Band SupportBand FrequenciesNarrow-band GPS, Galileo Rx: 1575.42 MHzWide-band GPS + GLONASS Rx: 1560–1606 MHzNarrow-band BeiDou Rx: 1561.098 MHzNarrow-band GLONASS Rx: 1601.72 MHz

RF SpecificationsRev 1 Jul.15 Proprietary and Confidential - Contents subject to change 13Designing Custom AntennasConsider the following points when designing custom antennas:•A skilled RF engineer should do the development to ensure that the RF performance is maintained.•If both UMTS and CDMA modules will be installed in the same platform, you may want to develop separate antennas for maximum performance.Determining the Antenna’s LocationWhen deciding where to put the antennas:•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.Disabling the Diversity AntennaUse the AT command !RXDEN=0 to disable receive diversity or !RXDEN=1 to enable receive diversity.Note: A diversity antenna is used to improve connection quality and reliability through redundancy. Because two antennas may experience difference interference effects (signal distortion, delay, etc.), when one antenna receives a degraded signal, the other may not be similarly affected.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 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. 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.

Hardware Integration Guide14 Proprietary and Confidential - Contents subject to change 4117682Interference and SensitivitySeveral interference sources can affect the module’s RF performance (RF desense). Common sources include power supply noise and device-generated RF.RF desense can be addressed through a combination of mitigation techniques (Methods to Mitigate Decreased Rx Performance on page 15) and radiated sensitivity measurement (Radiated Sensitivity Measurement on page 15).Note: The EM7455 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 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.•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 supplies

RF SpecificationsRev 1 Jul.15 Proprietary and Confidential - Contents subject to change 15Device-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. Methods to Mitigate Decreased Rx PerformanceIt is important to investigate sources of localized interference early in the design cycle. To reduce the effect of device-generated RF on Rx performance:•Put the antenna as far as possible from sources of interference. The drawback is that the module may be less convenient to use.•Shield the host device. The module itself is well shielded to avoid external interference. However, the antenna cannot be shielded for obvious reasons. In most 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.Radiated Spurious Emissions (RSE)When designing an antenna for use with AirPrime embedded modules, the host device with an AirPrime embedded module must satisfy any applicable standards / local regulatory bodies for radiated spurious emission (RSE) for receive-only mode and for transmit mode (transmitter is operating).Note that antenna impedance affects radiated emissions, which must be compared against the conducted 50-ohm emissions baseline. (AirPrime embedded modules meet the 50-ohm conducted emissions requirement.)Radiated Sensitivity MeasurementA wireless host device contains many noise sources that contribute to a reduction in Rx performance.To determine the extent of any receiver performance desensitization due to self-generated 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.
