    This chapter is under development—all recommendations must be considered as ‘TBD’. For industrial assembly guidelines, refer to [7] Customer Process Guidelines—AirPrime SL Series, available from your Sierra Wireless account representative. 8.1 General rules and constraints Clock and other high frequency digital signals (e.g. serial buses) should be routed as far as possible from the AirPrime SL808X Embedded Module analog signals.

  • Page 96: Antenna

    8.4 Antenna Another key issue in the design of a GSM terminal is the mechanical and electrical antenna adaptation. Sierra Wireless strongly recommends working with an antenna manufacturer either to develop an antenna adapted to the application or to adapt an existing solution to the application.

  • Page 97: Routing Constraints

    8.7 Routing constraints 8.7.1 Power supply Since the maximum peak current can reach 2 A, Sierra Wireless strongly recommends having a large width for the layout of the power supply signal (to avoid voltage loss between the external power supply and the AirPrime SL808X Embedded Module supply).

    Basically, the characteristic impedance depends on the dielectric, the track width and the ground plane spacing. In order to respect this constraint, Sierra Wireless recommends using MicroStrip or StripLine structure and computing the Tracks width with a simulation tool (like AppCad shown in the figure below and that is available free of charge at http://www.agilent.com).
  • Page 99 Figure 8-3: AppCad screenshot for MicroStrip design If a multi-layered PCB is used, the RF path on the board must not cross any signal (digital, analog or supply). If necessary, use StripLine structure and route the digital line(s) "outside" the RF structure as shown in the figure below.

    Important: In order to follow regular changes in the GPRS standard and to offer a state-of- the-art operating system, Sierra Wireless recommends that the application designed around an embedded module (or embedded module based product) should allow easy operating system upgrades on the embedded module via the recommended firmware download protocol (see [6] AirCard/AirPrime USB Driver Developer’s Guide).

    Figure 9-2: Main serial link (UART1) debug access When it is necessary to download firmware into the AirPrime SL808X Embedded Module without going through the RS232 interface, access to the embedded module is forced via the debug connector. An economical solution consists of making the debug connection using 7 test points (TP) and placing these points on the edge of the application board.
