1 1: Introduction The Sierra Wireless MC8805 PCI Express Mini Card is a compact, lightweight, wireless UMTS-based modem. The MC8805 provides DC-HSPA+, HSPA+, HSDPA, HSUPA, WCDMA, GSM, GPRS, EDGE, and GNSS connectivity for notebook, ultrabook, and tablet computers over several radio frequency bands. The device also supports 2G / 3G roaming, subject to carrier provisioning. Accessories The Universal Development Kit (UDK) is a hardware development platform for AirPrime MC-series modules.
Hardware Integration Guide 1. Manufacturers / part numbers are for reference only and are subject to change. Choose connectors that are appropriate for your own design.
2 2: Power Power supply The host provides power to the MC8805 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, see the AirPrime MC8805 Product Technical Specification Document & Customer Design Guidelines.
Hardware Integration Guide 10 Normal state of module between calls or data connections • Host power source is disconnected from the module and all voltages associated with the module are at 0 V. RF enabled Disconnected • • USB interface active Sleep Details Module is powered State Host is powered Table 2-1: Module power states (Continued) Module cycles between wake (polling the network) and sleep, at network providerdetermined interval.
3 3: RF Specifications The MC8805 operates on the frequency bands listed below. Table 3-1: WCDMA frequency band support1 Band Frequencies Band 1 WCDMA 2100 Tx: 1920–1980 MHz Rx: 2110–2170 MHz Band 2 WCDMA 1900 Tx: 1850–1910 MHz Rx: 1930–1990 MHz Band 5 WCDMA 850 Tx: 824–849 MHz Rx: 869–894 MHz Band 8 WCDMA 900 Tx: 880–915 MHz Rx: 925–960 MHz 1. WCDMA channel spacing is 5 MHz, but this can be adjusted to optimize performance in a particular deployment scenario.
Hardware Integration Guide RF connections When attaching antennas 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 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. • Match coaxial connections between the module and the antenna to 50 .
RF Specifications 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.). If the cables are near the noise sources, the noise may be coupled into the RF cable and into the antenna.
Hardware Integration Guide Interference from other wireless devices Wireless 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.
RF Specifications • 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 the radiated spurious emission (RSE) test cases described in: • CE/ETSI EN 301 908 (WCDMA), test numbers 5.3.1 (‘Radiated Emissions (UE)’) • CE/ETSI EN 301 511 (GSM), test 5.2.
