Power Supply
The power supply pins of SIM7100A include four VBAT pins (pin 62&63, pin 38&39). VBAT directly
supplies the power to RF and baseband circuit. VBAT directly supplies the power to RF PA and baseband
system. Power Supply Pin
4 VBAT pins are dedicated to connect the supply voltage.

Design Guide
Make sure that the input voltage at the VBAT pin will never drop below 3.15V even during a transmit
when the current consumption up to more than 700mA. If the power voltage drops below 3.15V, the
module may be shut down automatically. Using large tantalum capacitors (above 300uF) will be the best
way to reduce the voltage drops.
For the consideration of RF performance and system stability, some multi-layer ceramic chip (MLCC)
capacitors (0.1/1uF) need to be used for EMC because of their low ESR in high frequencies. Note that
capacitors should be put beside VBAT pins as close as possible. Also User should minimize the PCB trace
impedance from the power supply to the VBAT pins through widening the trace to 80 mil or more on the
board. The following figure is the recommended circuit.
Figure 7: VBAT input application circuit
Note: The Cd, Ce, Cb, Cc and Cf must be mounted for SIM7100A.For SIM5360 the Ca, Cb ,Ce, Cc and

Cf must be mounted.
In addition, in order to get a stable power source, it is suggested to use a zener diode of which reverse
zener voltage is 5.1V and dissipation power is more than 500mW.

Recommended Power supply circuit
We recommend DCDC or LDO is used for the power supply of the module, make sure that the peak
current of power components can rise up to more than 2A. The following figure is the reference design of
+5V input power supply. The designed output for the power supply is 3.8V, here a linear regulator can be
used.
Figure 8: Reference circuit of the LDO power supply
If there is a big difference between the input voltage and the desired output (VBAT), a switching converter
power will be preferable because of its better efficiency, especially at the high current situation. The
following figure is the reference circuit. Note that DCDC may deprave RF performance because of ripple
current intrinsically.

3.1.3
Voltage monitor
To monitor the power supply voltage, user can use the AT command “AT+CBC”, this command has two
parameters: the battery status and the voltage value (mV). It will return the capacity percentage and actual
value of battery (at the VBAT pin). The voltage is continuously measured at intervals, whenever the
measured battery voltage is lower than a specific value set by the AT command “AT+CVALARM”. For
example, if the voltage value is set to be 3.4V, the following URC will be presented: “warning! voltage is
low: 3.3v”.
If the voltage is lower than a specific value which is set by the AT command “AT+CPMVT”, the module
will be powered off automatically and AT commands cannot be executed any more.
Note: Under-voltage warning function and under-voltage power-off function are disabled by default.
For more information about these AT command, please refer to Document [1].

SIM7100A can be powered on by PWRKEY pin, which starts normal operating mode.
PWRKEY pin is pulled up with a 200k ohm resistor to 1.8V in module. User can power on the SIM7100A
by pulling the PWRKEY pin down for a short time. The power-on scenarios are illustrated in the following

The following methods can be used to power down SIM7100A. These procedures will make module
disconnect from the network and allow the software to enter a safe state, and then save data before
completely powering the module off.
Method 1: Power off SIM7100A by pulling the PWRKEY pin down
● Method 2: Power off SIM7100A by AT command
●
User can power off the SIM7100A by pulling PWRKEY down for a specific time. The power off scenario

User can also use the AT command “AT+CPOF” to power down the module. After that, the AT
commands cannot be executed any longer. The module enters the POWER DOWN mode.
VDD_EXT pin can be used to detect whether module is powered on or not. When module is powered
on and firmware goes ready, VDD_EXT will be high level.
Note: For details about “AT+CPOF”, please refer to Document [1].

Reset Function
SIM7100A also have a RESET pin (PIN4) to reset the module. This function is used as an emergency reset

Smart Machine Smart Decision
only when AT command “AT+CPOF” and the PWRKEY pin has no effect. User can pull the RESET pin
to ground, then the module will reset.
This pin is already pulled up in module, so the external pull-up resistor is not necessary. A 100nF capacitor
close to the RESET pin is strongly recommended. A reference circuit is recommended in the following
figure.

Antenna Design Guide
SIM7100A provides RF antenna interface. Customer’s antenna should be located in the host board and
connected to module’s antenna pad through micro-strip line or other types of RF trace and the trace
impedance must be controlled in 50Ω. The maximum gain of the LTE B2/WCDMA B2 antenna gain
should not exceed 3.4dBi, LTE B4 antenna gain should not exceed 1.9 dBi, LTE B5/WCDMA B5 antenna
gain should not exceed 2.8 dBi, LTE B17 antenna gain should not exceed 1dBi considering the SAR radio.
SIMCom recommends that the total insertion loss between the antenna pad and antenna should meet the
following requirements. No antenna gain may be used that would exceed the 2W EIRP power limit in
1900MHz band.The input impendence of the antenna should be 50Ω, and the VSWR should be less than 2.

F. Safety Caution
Table 54: Safety caution
Marks
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 to not operate normally for 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. Forget to think much of these
instructions may lead to the flight safety or offend against 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, for example no
mobile fee or a invalid SIM card. While you are in this condition and need emergent
help, please remember using 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.
