Charpt 1. Regulatory Information 1.1. SAR requirements specific to portable mobiles Mobile phones, PDAs or other portable transmitters and receivers incorporating a GSM module must be in accordance with the guidelines for human exposure to radio frequency energy. This requires the Specific Absorption Rate (SAR) of portable DLX3G based applications to be evaluated and approved for compliance with national and/or international regulations.

Feature Implementation Interfaces Module interface Antenna USB Surface mount device with solderable connection pads (SMT application interface). Land grid array (LGA) technology ensures high solder joint reliability and provides the possibility to use an optional module mounting socket. For more information on how to integrate SMT modules see also [7]. This application note comprises chapters on module mounting and application layout issues as well as on additional SMT application development equipment.
Feature Implementation Evaluation kit Evaluation module DLX3G module soldered onto a dedicated PCB that can be connected to an adapter in order to be mounted onto the DSB75. DSB75 DSB75 Development Support Board designed to test and type approve Gemalto M2M modules and provide a sample configuration for application engineering. A special adapter is required to connect the DLX3G evaluation module to the DSB75. 2.2.
Charpt 3. Application Interface 3.1. Operating Modes The table below briefly summarizes the various operating modes referred to in the following chapters Table: Overview of operating modes Mode Normal operation Function GSM / GPRS / UMTS / HSPA SLEEP GSM / GPRS / UMTS / HSPA IDLE Power saving set automatically when no call is in progress and the USB connection is suspended by host or not present and no active communication via ASC0.
Charpt 4. GNSS Receiver DLX3G integrates a GNSS receiver that offers the full performance of GPS/GLONASS technology. The GNSS receiver is able to continuously track all GPS/GLONASS satellites in view, thus providing accurate satellite position data. The integrated GNSS receiver supports the NMEA protocol via USB or ASC0 interface. NMEA is a combined electrical and data specification for communication between various (marine) electronic devices including GNSS receivers.
Charpt 5. Antenna Interfaces 5.1. GSM/UMTS Antenna Interface The DLX3G GSM/UMTS antenna interface comprises a main GSM/UMTS antenna as well as an optional UMTS Rx diversity antenna to improve signal reliability and quality1, The interface has an impedance of 50Ω. DLX3G is capable of sustaining a total mismatch at the antenna without any damage, even when transmitting at maximum RF power.
5.2. Antenna Installation The antenna is connected by soldering the antenna pads (ANT_WGSM; ANT_D RX) and their neighboring ground pads directly to the application’s PCB. Figure : Antenna pads (bottom view) The distance between the antenna pads and their neighboring GND pads has been optimized for best possible impedance. To prevent mismatch, special attention should be paid to these pads on the application’ PCB.

Pads marked "rfu" and qualified as "dnu" (do not use) may be soldered but should not be connected to an external application. Pads marked "rfu" and qualified as "GND" (ground) are assigned to ground with DLX3Gmodules, but may have different assignments with future Gemalto M2M products using thesame pad layout. Pads marked "GND" and qualified as "nc" (not connected) are internally not connected withDLX3G modules but may be soldered and arbitrarily be connected to external ground.
