Rev 0.1 (Draft A) Sep.10 Proprietary and Confidential 1133: RF IntegrationSupported RF bandsGround connection guidelinesWhen connecting the module to system ground:•Prevent noise leakage by establishing a very good ground connection to the module through the host connector.•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.Shielding guidelinesThe module is fully shielded to protect against EMI and to ensure compliance with FCC Part 15 - “Radio Frequency Devices” (or equivalent regulations in other jurisdictions).Note: This shielding must NOT be removed.Table 3-1: RF bandsTechnology BandFrequencies(MHz) SupportedTx RxGSMGSM 850 824–849 869–894 EGSM 900 880–915 925–960 DCS 1800 1710–1785 1805–1880 PCS 1900 1850–1910 1930–1990 WCDMAaa.

AirPrime SL8080 Series Hardware Integration Guide12 Proprietary and Confidential 2400058Antenna guidelinesChoosing the correct antenna and cablingConsider the following points for appropriate antenna selection:•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.Determining the antenna’s locationConsider the following points when deciding where to place 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.RF desense sourcesCommon sources of interference that may affect the module’s RF performance (RF desense) include•Power supply noise·Can lead to noise in the RF signal·Module power supply ripple limit <= 100 mVp-p 1 Hz–100 kHz•Interference from other embedded wireless devices·Any harmonics, sub-harmonics, or cross-products of signals that fall in the module’s Rx range may cause spurious response, resulting in decreased Rx performanc.·Tx power and corresponding broadband noise may overload or increase the noise floor of the module’s receiver, resulting in RF desense.·Severity of interference depends on proximity of other antennas to the module’s antenna.s•Host electronic device-generated RF·Proximity of host electronics to the module’s antenna can contribute to decreased Rx performance.·Some devices include microprocessor and memory, display panel and dispaly drivers, and switching mode power supplies.
