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.
Since the SAR value varies significantly with the individual product design
manufacturers are advised to submit their product for approval if designed for
portable use. For US and European markets the relevant directives are
mentioned below. It is the responsibility of the manufacturer of the final product
to verify whether or not further standards, recommendations or directives are in
force outside these areas.
Products intended for sale on US markets
ES 59005/ANSI C95.1 Considerations for evaluation of human exposure to
electromagnetic fields (EMFs) from mobile
telecommunication equipment (MTE) in the frequency
range 30MHz - 6GHz
Products intended for sale on European markets
EN 50360
Product standard to demonstrate the compliance of
mobile phones with the basic restrictions related to
human exposure to electromagnetic fields (300MHz 3GHz)
IMPORTANT：
Manufacturers of portable applications based on DLX3G modules are required
to have their final product certified and apply for their own FCC Grant and
Industry Canada Certificate relat-ed to the specific portable mobile.

Normal shutdown after sending the AT^SMSO command. Only a voltage
regulator is active for powering the RTC. Software is not active. Interfaces
are not accessible. Operating voltage (connected to BATT+) remains
applied.
Airplane mode shuts down the radio part of the module, causes the
module to log off from the GSM/GPRS network and disables all AT
commands whose execution requires a radio connection. Airplane mode
can be controlled by AT command.

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. It has been defined and controlled by the US-based National Marine
Electronics Association.
Depending on the receiver’s knowledge of last position, current time and
ephemeris data, the receiver’s startup time (i.e., TTFF = Time-To-First-Fix) may
vary: If the receiver has no knowledge of its last position or time, a startup takes
considerably longer than if the receiver has still knowledge of its last position,
time and almanac or has still access to valid ephemeris data and the precise
time.
By default, the GNSS receiver is switched off. It has to be switched on and
configured using AT commands.
DLX3G User Guide
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.
The external antenna must be matched properly to achieve best performance regarding
radiated power, modulation accuracy and harmonic suppression. Matching networks
are not included on the DLX3G PCB and should be placed in the host application, if
the antenna does not have an impedance of 50Ω.
Regarding the return loss DLX3G provides the following values in the active band:
Table: Return loss in the active band
State of module Return loss of
module
Receive
> 8dB
Transmit
not applicable
Idle
< 5dB
Recommended return loss of application
> 12dB
> 12dB
not applicable
By delivery default the optional UMTS Rx diversity antenna is configured as available for the modu
le. To avoid negative side effects and performance degradation it is recommended to disable the div
ersity antenna path if
- the host application does not support a diversity antenna
- the host application includes a diversity antenna - but a 3G network simulator is used for development and
performance tests.
DLX3G User Guide

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.
The wiring of the antenna connection, starting from the antenna pad to the
application’s antenna should result in a 50 Ω line impedance. Line width and distance
to the GND plane need to be optimized with regard to the PCB’s layer stack.
To prevent receiver desensitization due to interferences generated by fast transients like
high speed clocks on the external application PCB, it is recommended to realize the
antenna connection line using embedded Stripline rather than Micro Stripline
technology.
For type approval purposes, the use of a 50Ω coaxial antenna connector (U.FL-R-SMT)
might be necessary. In this case the U.FL-R-SMT connector should be placed as close

as possible to DLX3G‘s antenna pad.

Temperature measured on DLX3G board
1. Operating temperature range according to 3GPP type approval specification
2. Extended operation allows normal mode data transmissions for limited time until
automatic thermal shutdown takes effect.
Within the extended temperature range (outside the operating temperature range)
there should not be any unrecoverable malfunctioning. General performance
parameters like Pout or RX sensitivity however may be reduced in their values.
The module’s life time may also be affected, if deviating from a general
temperature allocation model .
3. Due to temperature measurement uncertainty, a tolerance on the stated shutdown
thresholds may occur. The possible deviation is in the range of ± 2°C at the over
temperature and under temperature limit.
Note that within the specified operating temperature ranges the board temperature may
vary to a great extent depending on operating mode, used frequency band, radio output
power and current supply voltage. Note also the differences and dependencies that
usually exist between board (PCB) temperature and ambient temperature. The possible
ambient temperature range depends on the mechanical application design including the
module and the PCB with its size and layout. A thermal solution will have to take these
differences into account and should therefore be an integral part of application design.

Board and ambient temperature differences
6.1.1.Temperature Allocation Model
The temperature allocation model shown in Table 21 assumes shares of a module’s
average lifetime of 10 years (given in %) during which the module is operated at
certain temperatures.

1.Based on an assumed average module lifetime of 10 years (=100%).
Any deviations from the above temperature allocation model may reduce the module’s
life span, for example if the module is operated close to the maximum automatic
shutdown temperature not only for 1% but for 20% of its product life.
6.2. Pad Assignment and Signal Description
The SMT application interface on the DLX3G provides connecting pads to integrate
the module into external applications.
Please note that a number of connecting pads are marked as reserved for
future use (rfu) or ground (GND) and further qualified as either (dnu), (GND) or
(nc):
DLX3G User Guide
14

 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.
Strongly recommends to solder all connecting pads for mechanical stability and heat
dissipation.

1. Test condition: Assumes 300 seconds timeout, QoS=1000m, and 50% yield.
2. Test condition: TTFF is defined for an open sky environment, i.e., with a clear view to the sky and a
min-imum signal level of -130dBm at the antenna for at least 3…4 satellites. This signal level
represents C/No=42dB in an NMEA $GPGSV message.
3. For test purposes a cold start may be triggered by AT command: AT^SBNW="agps",-1.
4. To optimize GPS start-up behavior, it is recommended to backup the module’s internal real time clock
via VDDLP line as described.
Through the external GNSS antenna DC feeding the module is able to supply an active
