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 XT65/XT75 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 European and US 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.

SELV Requirements
The power supply connected to the XT65/XT75 module shall be in compliance with the SELV requirements
defined in EN 60950-1. See also Section 6.1 for further detail.
1.3.4
Safety Precautions
The following safety precautions must be observed during all phases of the operation, usage, service or repair
of any cellular terminal or mobile incorporating XT65/XT75. Manufacturers of the cellular terminal are advised to
convey the following safety information to users and operating personnel and to incorporate these guidelines into
all manuals supplied with the product. Failure to comply with these precautions violates safety standards of
design, manufacture and intended use of the product. Siemens AG assumes no liability for customer’s failure to
comply with these precautions.
When in a hospital or other health care facility, observe the restrictions on the use of mobiles.
Switch the cellular terminal or mobile off, if instructed to do so by the guidelines posted in sensitive areas. Medical equipment may be sensitive to RF energy.
The operation of cardiac pacemakers, other implanted medical equipment and hearing aids
can be affected by interference from cellular terminals or mobiles placed close to the device.
If in doubt about potential danger, contact the physician or the manufacturer of the device to
verify that the equipment is properly shielded. Pacemaker patients are advised to keep their
hand-held mobile away from the pacemaker, while it is on.
Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it cannot be
switched on inadvertently. The operation of wireless appliances in an aircraft is forbidden to
prevent interference with communications systems. Failure to observe these instructions may
lead to the suspension or denial of cellular services to the offender, legal action, or both.
Do not operate the cellular terminal or mobile in the presence of flammable gases or fumes.
Switch off the cellular terminal when you are near petrol stations, fuel depots, chemical plants
or where blasting operations are in progress. Operation of any electrical equipment in potentially explosive atmospheres can constitute a safety hazard.
Your cellular terminal or mobile receives and transmits radio frequency energy while switched
on. Remember that interference can occur if it is used close to TV sets, radios, computers or
inadequately shielded equipment. Follow any special regulations and always switch off the
cellular terminal or mobile wherever forbidden, or when you suspect that it may cause interference or danger.
Road safety comes first! Do not use a hand-held cellular terminal or mobile when driving a
vehicle, unless it is securely mounted in a holder for speakerphone operation. Before making
a call with a hand-held terminal or mobile, park the vehicle.
Speakerphones must be installed by qualified personnel. Faulty installation or operation can
constitute a safety hazard.

1.3 Regulatory and Type Approval Information
IMPORTANT!
Cellular terminals or mobiles operate using radio signals and cellular networks. Because of
this, connection cannot be guaranteed at all times under all conditions. Therefore, you should
never rely solely upon any wireless device for essential communications, for example emergency calls.
Remember, in order to make or receive calls, the cellular terminal or mobile must be switched
on and in a service area with adequate cellular signal strength.
Some networks do not allow for emergency calls if certain network services or phone features
are in use (e.g. lock functions, fixed dialing etc.). You may need to deactivate those features
before you can make an emergency call.
Some networks require that a valid SIM card be properly inserted in the cellular terminal or
mobile.
Bear in mind that exposure to excessive levels of noise can cause physical damage to users!
With regard to acoustic shock, the cellular application must be designed to avoid unintentional
increase of amplification, e.g. for a highly sensitive earpiece. A protection circuit should be
implemented in the cellular application.

XT65/XT75 Hardware Interface Overview
3.1 Operating Modes
3.1
Operating Modes
The table below briefly summarizes the various operating modes available for the module.
Table 5: Overview of operating modes
Normal operation
GSM / GPRS SLEEP
Various power save modes set with AT+CFUN command.
Software is active to minimum extent. If the module was registered to the GSM network in IDLE mode, it is registered and paging with the BTS in SLEEP mode, too. Power saving can be
chosen at different levels: The NON-CYCLIC SLEEP mode
(AT+CFUN=0) disables the AT interface. The CYCLIC SLEEP
modes AT+CFUN=7 and 9 alternatingly activate and deactivate
the AT interfaces to allow permanent access to all AT commands.
POWER DOWN
GSM IDLE
Software is active. Once registered to the GSM network, paging
with BTS is carried out. The module is ready to send and receive.
GSM TALK
Connection between two subscribers is in progress. Power consumption depends on network coverage individual settings, such
as DTX off/on, FR/EFR/HR, hopping sequences, antenna.
GPRS IDLE
EGPRS IDLE
Module is ready for GPRS/EGPRS data transfer, but no data is
currently sent or received. Power consumption depends on network settings and GPRS/EGPRS configuration (e.g. multislot
settings).
GPRS DATA
EGPRS DATA
GPRS/EGPRS data transfer in progress. Power consumption
depends on network settings (e.g. power control level), uplink /
downlink data rates, GPRS configuration (e.g. used multislot settings) and reduction of maximum output power.
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
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 using the AT commands AT^SCFG and AT+CALA:
•
•
•
With AT^SCFG=MEopMode/Airplane/OnStart the module can be configured to enter
the Airplane mode each time when switched on or reset.
The parameter AT^SCFG=MEopMode/Airplane can be used to switch back and forth
between Normal mode and Airplane mode any time during operation.
Setting an alarm time with AT+CALA followed by AT^SMSO wakes the module up into
Airplane mode at the scheduled time.
Charge-only mode Limited operation for battery powered applications. Enables charging while module is
detached from GSM network. Limited number of AT commands is accessible. Chargeonly mode applies when the charger is connected if the module was powered down with
AT^SMSO.
Charge mode during normal operation
Normal operation (SLEEP, IDLE, TALK, GPRS/EGPRS IDLE, GPRS/EGPRS DATA) and
charging running in parallel. Charge mode changes to Charge-only mode when the module is powered down before charging has been completed.

4 GSM Antenna Interface
GSM Antenna Interface
The GSM interface has an impedance of 50Ω. XT65/XT75 is capable of sustaining a total mismatch at the
antenna connector without any damage, even when transmitting at maximum RF power. DC electric strength is
given (see Table 11).
The external antenna must be matched properly to achieve best performance regarding radiated power, DCpower consumption, modulation accuracy and harmonic suppression. Antenna matching networks are not
included on the XT65/XT75 PCB and should be placed in the host application.
Regarding the return loss XT65/XT75 provides the following values in the active band:

Antenna Installation
To suit the physical design of individual applications XT65/XT75 offers two alternative approaches to connecting
the antenna:
•
Recommended approach: U.FL-R-SMT antenna connector from Hirose assembled on the component side of
the PCB.
Figure 1: GSM antenna connector placement
See Section 4.3 for connector details.
•
Antenna pad and grounding plane placed on the bottom side. See Section 4.2.
The U.FL-R-SMT connector has been chosen as antenna reference point (ARP) for the Siemens reference
equipment submitted to type approve XT65/XT75. All RF data specified throughout this manual are related to the
ARP. For compliance with the test results of the Siemens type approval you are advised to give priority to the
connector, rather than using the antenna pad.
IMPORTANT: Both solutions can only be applied alternatively. This means, whenever an antenna is plugged to
the Hirose connector, the pad must not be used. Vice versa, if the antenna is connected to the pad, then the
Hirose connector must be left empty.

Antenna Pad
The antenna can be soldered to the pad, or attached via contact springs. For proper grounding connect the
antenna to the ground plane on the bottom of XT65/XT75 which must be connected to the ground plane of the
application.
If you decide to use the antenna pad take into account that the pad has not been intended as antenna reference
point (ARP) for the Siemens XT65/XT75 type approval. The antenna pad is provided only as an alternative option
which can be used, for example, if the recommended Hirose connection does not fit into your antenna design.
Please ensure that the antenna pad does not come into contact with the holding device or any other components
of the host application. It needs to be surrounded by a restricted area filled with air, which must also be reserved
0.8mm in height.

Also, consider that according to the GSM recommendations TS 45.005 and TS 51.010-01 a 50Ω connector is
mandatory for type approval measurements. This requires GSM devices with an integral antenna to be temporarily equipped with a suitable connector or a low loss RF cable with adapter.

Notes on soldering:
•
•
To prevent damage to the module and to obtain long-term solder joint properties you are advised to maintain
the standards of good engineering practice for soldering.
Be sure to solder the antenna core to the pad and the shielding of the coax cable to the ground plane of the
module next to the antenna pad. The direction of the cable is not relevant from the electrical point of view.

5.2 GPS Antenna
5.2
GPS Antenna
It is possible to connect active or passive GPS antennas. In either case they must have 50 Ohm impedance. The
application should be designed in a way to achieve a minimum of 6dB decoupling between the GSM/DCS/PCS
antenna path and the GPS antenna path. Please note that the GPS antenna must be isolated for ESD protection
(to withstand a voltage resistance up to 8kV air discharge).
Active versus Passive Antennas
Passive antennas contain only the radiating element, e.g. the ceramic patch or the quadrifilar dipole structure.
Sometimes they also contain a passive matching network to match the electrical connection to 50 Ohms impedance. Note: Passive antenna need not have a DC connection to ground.
Active antennas have an integrated low-noise amplifier (in some cases an additional GPS band pass filter). This
is beneficial in two respects: First, the losses of the cable do no longer influence the overall noise figure of the
GPS receiver system. Secondly, even the receiver noise figure can be higher without sacrificing performance.
Active antennas need a power supply that will contribute to GPS system power consumption, typically in the
region of 5 to 20 mA. The supply voltage is fed to the antenna through the coaxial RF cable.
Inside the antenna, the DC component on the inner conductor will be separated from the RF signal and routed
to the supply pin of the LNA.
The use of an active antenna is always advisable, if the RF-cable length between receiver and antenna exceeds
about 10 cm.

•
•
•
•
•
A wide range of active patch or quadrifilar
dipole antennas is available in the market.
They differ in size, sensitivity, selectivity and
power consumption
Less sensitive to jamming than a passive
antenna, as the placement of the active
antenna is usually some distance away of
other noise or signal radiating devices.
Needs more power than a passive antenna
Easier and less sensitive to jamming.
More freedom to place the antenna1
1.
•
•
•
•
•
•
Passive patch antennas or helical antennas are available in different form factors and sensitivity
Antenna must be connected with a low insertion loss
line to the GPS module to ensure a good GPS sensitivity.
The PCB design with a passive antenna must consider
the sensitivity of the GPS antenna to other radiating circuits or general signal jamming.
Due to the proximity of the GPS antenna to other electronic circuits, in-band jamming may become a critical
issue.
Only suitable for RF experts!
Needs more experience in RF design.
Requires more effort to optimise the circuit design to
minimize jamming into the antenna and the antenna
signal routing.
Some cars for instance have a metallic coating on the windshield. GPS reception may not be possible in such a
car. There is usually a small section, typically behind the rear view mirror without the coating for mobile phone
and GPS antennas. The antenna has to be placed with optimal sky visibility. An external antenna (e.g. with a
magnetic base) is easier to use and usually allows a better positioning.
Note: If you are not an expert in RF designs, you should implement an active antenna setup and place the
antenna away from any emitting circuits.

PWR_IND
VIHmax = 10V
PWR_IND (Power Indicator) notifies the module’s on/off state.
VOLmax = 0.4V at Imax = 2mA
PWR_IND is an open collector
that needs to be connected to an
external pull-up resistor. Low state
of the open collector indicates that
the module is on. Vice versa, high
level notifies the Power-down
mode.
Therefore, the pin may be used to
enable external voltage regulators
which supply an external logic for
communication with the module,
e.g. level converters.

Restrictions during SLEEP mode:
During SLEEP Mode the ADC is shut down temporarily (per default). Please make sure that during SLEEP Mode
shutdown the ADCx_IN input voltage does not exceed ±0.3V. The input current (reverse feeding) may reach 3mA!
If SLEEP Mode is activated there are three protection possibilities:
- Use an RC combination for current limitation.
Advantages: Lowest current consumption at SLEEP Mode, small component count, high input resistance
Disadvantages: Lower input resistance at Sleep Mode (100k only).
- Use the AT^SNFM=,1 command to enable the ADC supply continuously .
Advantages: No additional component components needed.
Disadvantages: Higher current consumption in SLEEP (about 2mA)
- Detect presence of VMIC-voltage. If VMIC is off, make sure that ADCx_IN input voltages does not exceed ±0.3V
Advantages: Lowest current, high input resistance.
Disadvantages: Effort for SLEEP Mode (VMIC) detection.

There are many ways to properly install XT65/XT75 in the host device. An efficient approach is to mount the
XT65/XT75 PCB to a frame, plate, rack or chassis.
Fasteners can be M2 screws plus suitable washers, circuit board spacers, or customized screws, clamps, or
brackets. In addition, the board-to-board connection can also be utilized to achieve better support. To help you
find appropriate spacers a list of selected screws and distance sleeves for 3mm stacking height can be found in
Section 9.2.
When using the two small holes take care that the screws are inserted with the screw head on the bottom of the
XT65/XT75 PCB. Screws for the large holes can be inserted from top or bottom.
For proper grounding it is strongly recommended to use large ground plane on the bottom of board in addition to
the five GND pins of the board-to-board connector. The ground plane may also be used to attach cooling elements, e.g. a heat sink or thermally conductive tape. Please take care that attached cooling elements do not
touch the antenna pads on the module’s bottom side, as this may lead a short-circuit.
To prevent mechanical damage, be careful not to force, bend or twist the module. Be sure it is positioned flat
against the host device.
