Power Supply
On VBAT pads, a ripple current up to 2A typically, may cause voltage drop. Therefore, the power
supply for these pads must be able to provide sufficient current up to more than 2A in order to
avoid the voltage drop of more than 300mV.

Power supply Design Guide
Make sure that the voltage on the VBAT pins will never drop below 3.4V.
Note: If the power supply for BAT pins can support up to 2A, using a total of more than 220uF
capacitors is recommended, or else users must use a total of 1000uF capacitors, in order to avoid
the voltage drop of more than 300mV.
Some multi-layer ceramic chip (MLCC) capacitors (0.1/1uF) with low ESR in high frequency band
can be used for EMC.
These capacitors should be put as close as possible to VBAT pads. Also, user should keep VBAT
trace on the circuit board wider than 2 mm to minimize PCB trace impedance. The following figure
shows the recommended circuit.

Recommended Power Supply Circuit
It is recommended that a switching modepower supply or linear regulator power supply is used. It
is important to make sure that all the components used in the power supply circuit can resist a peak
current up to 2A.
The following figure shows the linear regulatorreference circuit with 5V input and 3.8V output.
Figure 6: Linear regulator reference circuit
If there is a big voltage difference between input and output for VBAT power supply, orthe
efficiency is extremely important,then a switching mode power supply will be preferable. The
following figure shows theswitching mode power supply reference circuit.
Figure 7: Switching modepower supply reference circuit
Note: The Switching Mode power supply solution for VBAT must be chosen carefully against
Electro Magnetic Interference and ripple current from depraving RF performance.

Voltage Monitor
To monitor the VBAT voltage, the AT command “AT+CBC” can be used.
For monitoring the VBAT voltage outside or within a special range, the AT command
“AT+CVALARM” can be used to enable the under-voltage warning function.
If users need to power off Module, when the VBAT voltage is out of a range, the AT command
“AT+CPMVT” can be used to enable under-voltage power-off function.
Note: Under-voltage warning function and under-voltage power-off function are disabled by
default. For more information about these AT commands, please refer to Document [1].

RI and DTR Behavior
The RI pin can be used to interrupt output signal to inform the host controller such as application
CPU.
Normally RI will stay at high level until certain conditions such as receiving SMS, or a URC report
come in. It will then change to low level. It will stay low until the host controller clears the
interrupted event with “AT+CRIRS” AT command.
Figure 15: RI behaviour（SMS and URC report）
Normally RI will be kept high until a voice call, then it will output periodic rectangular wave with
5900ms low level and 100ms high level. It will output this kind of periodic rectangular wave until
the call is answered or hung up.
Figure 16: RI behaviour（voice call）
Note: For more details of AT commands about UART, please refer to document [1] and [22].
DTR pin can be used to wake Module from sleep. When Module enters sleep mode, pulling down
DTR can wake Module.

USB Application Guide
Module can be used as a USB device. Module supports the USB suspend and resume mechanism
which can reduce power consumption. If there is no data transmission on the USB bus, Module will
enter suspend mode automatically and will be resumed by some events such as voice call, receiving
SMS, etc.
Figure 17: USB reference circuit
Because of the high bit rate on USB bus, more attention should be paid to the influence of the
junction capacitance of the ESD component on USB data lines. Typically, the capacitance should
be less than1pF. It is recommended to use an ESD protection component such as ESD9L5.0ST5G
provided by On Semiconductor (www.onsemi.com ).
D3 is suggested to select the diode with anti-ESD and voltage surge function, or customer could
add a ZENER diode for surge clamping. The recommend diodes list please refer to table 7.

WCDMA/LTE Antenna Design Guide
Users should connect antennas to Module’s antenna pads through the micro-strip line or other types
of RF trace. The trace impedance must be controlled in 50Ω. SIMCom recommends that the total
insertion loss between Module and antenna should meet the following requirements:
Table 25: Trace Loss

Loss
700MHz-960MHz
<0.5dB
1710MHz-2170MHz
<0.9dB
2300MHz-2650MHz
<1.2dB
To facilitate the antenna tuning and certification test, a RF connector and an antenna matching
circuit should be added. The following figure is the recommended circuit.
Figure 27: Antenna matching circuit (MAIN_ANT)
In above figure, the components R1,C1,C2 and R2 are used for antenna matching, the value of
components can only be achieved after the antenna tuning and usually provided by antenna vendor.
By default, the R1, R2 are 0Ω resistors, and the C1, C2 are reserved for tuning. The component D1
is a TVS for ESD protection, and it is optional for users according to application environment.
The RF test connector is used for the conducted RF performance test, and should be placed as close
as to the module’s MAIN_ANT pin. The traces impedance between Module and antenna must be
controlled in 50Ω.

Note：SIMCom suggests the LTE auxiliary antenna to be kept on, since there are many high
bands in the designing of FDD-LTE. Because of the high insert loss of the RF cable and layout
lines, the receiver sensitivity of these bands above will have risk to meet the authentication
without the diversity antenna.For more details about auxiliary antenna design notice,please

GNSS
SIM7600A merges GNSS satellite and network information to provide a high-availability solution
that offers industry-leading accuracy and performance. This solution performs well, even in very
challenging environmental conditions where conventional GNSS receivers fail, and provides a
platform to enable wireless operators to address both location-based services and emergency
mandates.

4.3.2
GNSS Application Guide
Users can adopt an active antenna or a passive antenna as GNSS signal transceiver. In this
document, all GNSS specification mentioned is from passive antenna. The following is the
reference circuit.
Figure 30: Active antenna circuit

In above figures, the components C1 and L1, L2 are used for antenna matching, the values of the
components can only be obtained after the antenna tuning and usually provided by antenna vendor.
C2 in Figure 29 is used for DC blocking. L3 is the matching component of the external LNA, and
the value of L3 is determined by the LNA characteristic and PCB layout. Both VDD of active
antenna and V_LNA need external power supplies which should be considered according to active
antenna and LNA characteristic. LDO/DCDC is recommended to get lower current consuming by
shutting down active antennas and LNA when GNSS is not working.

GNSS can be used by NMEA port. User can select NMEA as output through UART or USB.
NMEA sentences are automatic and no command is provided. NMEA sentences include GSV, GGA,
RMC, GSA, and VTG. Before using GNSS, user should configure SIM7600A in proper operating
mode by AT command. Please refer to related document for details. SIM7600A can also get
position location information through AT directly.
Note: GNSS is closed by default, it could be started by AT+CGPS. The AT command has two
parameters, the first is on/off, and the second is GNSS mode. Default mode is standalone mode.
AGPS mode needs more support from the mobile telecommunication network. Please refer to

Several hardware and software conditions must be satisfied together in order to let Module enter
into sleep mode:
1. UART condition
2. USB condition
3. Software condition
Note: Before designing, pay attention to how to realize sleeping/waking function and refer to
Document [26] for more details.
5.3.3
Minimum Functionality Mode and Flight Mode
Minimum functionality mode ceasesa majority functionof module, thus minimizing the power
consumption. This mode is set by the AT command which provides a choice of the functionality
levels.
● AT+CFUN=0: Minimum functionality
● AT+CFUN=1: Full functionality (Default)
● AT+CFUN=4: Flight mode
If Module has been set to minimum functionality mode, the RF function and USIM card function
will be closed. In this case, the serial port and USB are still accessible, but RF function and USIM
card will be unavailable.
If Module has been set to flight mode, the RF function will be closed. In this case, the serial port
and USB are still accessible, but RF function will be unavailable.
When Module is in minimum functionality or flight mode, it can return to full functionality by the

Requirements
When in a hospital or other health care facility, observe the restrictions about the use
of mobiles. Switch the cellular terminal or mobile off, medical equipment may be
sensitive and not operate normally due to RF energy interference.
Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it is
switched off. The operation of wireless appliances in an aircraft is forbidden to
prevent interference with communication systems. Forgeting to think much of these
instructions may impact the flight safety or offend local 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. RF interference can occur if it is used close to TV sets, radios,
computers or other electric equipment.
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 hands free operation.
Before making a call with a hand-held terminal or mobile, park the vehicle.
GSM cellular terminals or mobiles operate over radio frequency signals and cellular
networks and cannot be guaranteed to connect in all conditions, especially with a
mobile fee or an invalid SIM card. While you are in this condition and need emergent
help, please remember to use emergency calls. 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 call if certain network services or phone
features are in use (e.g. lock functions, fixed dialing etc.). You may have to
deactivate those features before you can make an emergency call.
Also, some networks require that a valid SIM card be properly inserted in the cellular
terminal or mobile.
