    EMI emissions, maximum thermal conduction, mechanical integrity, and voice quality. The Enabler LPP G module is a very compact, high performance design, yet it is easy to interface into the final product. In order to realize its full potential, designers should pay close attention to ground structures, the routing of RF and Digital traces, and the size of the power supply lines.

    4.5.1. Advanced tips for an RF friendly layout 4.5.1.1. Ground Plane To ensure the lowest possible EMI emissions and maximum thermal conductivity, it is recommended that all metal tabs on the GSM module shield must be soldered down onto a continuous ground plane that runs under the entire module.

  • Page 19: Thermal Relief

    4.5.1.2. Thermal Relief Because the ground plane acts as a large heat sink, it can affect the solderability of components. A common method to reduce this effect is to use thermal relief around the pad in question. However, great care must be taken when using thermal relief for high current or high frequency applications For example, a large thermal relief like the one shown in Figure 2 can serve the purpose for general applications such as low current, low speed data lines, DC connections and audio...

    4.5.1.4. Vbat Input The Enabler Vbat input can have a relative high current draw that can fluctuate rapidly, especially when transmitting at max power and burst mode. The Vbat interface must be designed to provide the required instantaneous voltage and current with minimal voltage droop.

    The guidelines presented in IPC/JEDEC J-STD-020C for handling, preparation, and reflow of lead-free devices should be applied to the Enabler LPP G module. Care should be taken to minimize module moisture exposure before reflow. The module is classified as a Type 3 MSL (moisture sensitivity level).
