3.5 GENERAL DESIGN GUIDELINES FOR UTILIZING
ENFORA GSM MODULES
The following guidelines are provided in an effort to allow Enabler III LPP module
users to successfully implement their PCB layout to obtain the best performance.
This includes the lowest possible EMI emissions, maximum thermal conduction,
mechanical integrity, and voice quality. The Enabler III LPP 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.
Warning: These design tips are strictly guidelines and are not
meant to be a complete list of items that guarantee actual
performance. Each application is different and may require
variation from these guidelines; however, care should be given to
utilize these sound engineering principles whenever possible.
