The 4 VBAT pads supply the power to RF and baseband circuits directly. On VBAT pads, the ripple current up to 2A typically, due to GSM/GPRS emission burst (every 4.615ms), may cause voltage drop. So 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 is more than 300mV. The following figure shows the VBAT voltage ripple wave at the maximum power transmit phase. 577us 4.615ms IVBAT VBAT B urst:2A Max:300mV Figure 5: VBAT voltage drop during burst emission (GSM/GPRS) Note: The test condition: The voltage of power supply for VBAT is 3.8V, Cd=100 F tantalum capacitor (ESR=0.7) and Cf=100nF (Please refer to Figure 6Application circuit).

20 uA SIM7600SA-H_User Manual_V1.00 2017-10-11 Smart Machine Smart Decision 3.1.1 Power Supply Design Guide Make sure that the voltage on the VBAT pins will never drop below 3.4V, even during a transmit burst, when current consumption may rise up to 2A. If the voltage drops below 3.4V, the RF performance may be affected. Note: If the power supply for VBAT pins can support up to 2A, using a total of more than 300uF capacitors is recommended, or else users must using a total of 1000uF capacitors typically, in order to avoid the voltage drop is 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, users should keep VBAT trace on circuit board wider than 2 mm to minimize PCB trace impedance. The following figure shows the recommended circuit.

MAIN ANT RF connector Matching circuit R1 C1 R2 C2 D1 MAIN_ANT GND 82 41 MODULE Figure 30: Antenna matching circuit (MAIN_ANT) In above figure, the components R1, C1, C2 and R2 are used for antenna matching, the values of components can only be achieved after the antenna tuning and usually provided by antenna vendor. By default, the R1, R2 are 0 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 modules MAIN_ANT pin. The traces impedance between SIM7600SA-H and antenna must be controlled in 50 . SIM7600SA-H_User Manual_V1.00 2017-10-11 Smart Machine Smart Decision Table 28: Recommended TVS Package 0201 0402 Part Number LXES03AAA1-154 LXES15AAA1-153 Vender Murata Murata NoteSIMCom suggests the LTE auxiliary antenna to be kept on, since there are many high bands in the designing of TDD-LTE, such as band38, band40 and band41. 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 refer to document [25]. 4.3 GNSS SIM7600SA-H merges GNSS (GPS/GLONASS) 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. 4.3.1 GNSS Technical specification Tracking sensitivity: -159 dBmGPS/-158 dBmGLONASS Cold-start sensitivity: -148 dBm Accuracy (Open Sky): 2.5m (CEP50) TTFF (Open Sky) : Hot start <1s, Cold start<35s SIM7600SA-H_User Manual_V1.00 2017-10-11 Smart Machine Smart Decision Receiver Type: 16-channel, C/A Code GPS L1 Frequency: 1575.421.023MHz GLONASS: 1597.5~1605.8 MHz Update rate: Default 1 Hz GNSS data format: NMEA-0183 GNSS Current consumption : 100mA (GSM/CDMA 1X/UMTS/LTE Sleep ,in total on VBAT pins) GNSS antenna: Passive/Active antenna Note: If the antenna is active type, the power should be given by main board because there is no power supply on the GPS antenna pad. If the antenna is passive, it is suggested that the external LNA should be used. 4.3.2 GNSS Application Guide Users can adopt an active antenna or a passive antenna to SIM7600SA-H. If using a passive antenna, an external LNA is a must to get better performance. The following figures are the reference circuits. 10 ohm GNSS Active ANT VDD 47nH GND 80 Matching circuit GNSS_ANT 79 GND 78 L1 L2 MODULE Figure 32: Active antenna circuit V_LNA GNSS Passive ANT LNA L3 SAW Matching circuit C1 L1 L2 GND 80 GNSS_ANT 79 GND 78 MODULE SIM7600SA-H_User Manual_V1.00 2017-10-11 Figure 33: Passive antenna circuit (Default) Smart Machine Smart Decision In above figures, the components C1, L1 and L2 are used for antenna matching. Usually, the values of the components can only be achieved after antenna tuning and usually provided by antenna vendor. C2 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 tested by NMEA port. NMEA sentences can be obtained through UART or USB automatically. NMEA sentences include GSV, GGA, RMC, GSA, and VTG. Before using GNSS, user should configure SIM7600SA-H in proper operating mode by AT command. Please refer to related documents for details. SIM7600SA-H can also get position location information through AT directly. Note: GNSS is closed by default and can 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 document [24] for more details.

Module is registered to the network, and the module is ready to communicate. Connection between two subscribers is in progress. In this case, the power consumption depends on network settings such as DTX off/on, FR/EFR/HR, hopping sequences, and antenna. Module is ready for data transmission, but no data is currently sent or received. In this case, power consumption depends on network settings. There is data transmission in progress. In this case, power consumption is related to network settings (e.g. power control level);

uplink/downlink data rates, etc. Minimum functionality mode AT command AT+CFUN=0 AT+CSCLK=1 can be used to set the module to a minimum functionality mode without removing the SIM7600SA-H_User Manual_V1.00 2017-10-11 Smart Machine Smart Decision power supply. In this mode, the RF part of the module will not work and the USIM card will not be accessible, but the serial port and USB port are still accessible. The power consumption in this mode is lower than normal mode. AT command AT+CFUN=4 or pulling down the FLIGHTMODE pin can be used to set the module to flight mode without removing the power supply. In this mode, the RF part of the module will not work, but the serial port and USB port are still accessible. The power consumption in this mode is lower than normal mode. Module will go into power off mode by sending the AT command AT+CPOF or pull down the PWRKEY pin, normally. In this mode the power management unit shuts down the power supply, and software is not active. The serial port and USB are is not accessible. Flight mode Power off 5.3.2 Sleep mode 1. UART condition 2. USB condition 3. Software condition In sleep mode, the current consumption of module will be reduced to the minimal level, and module can still receive paging message and SMS. Several hardware and software conditions must be satisfied together in order to let SIM7600SA-H enter into sleep mode:

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 ceases a majority function of 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 SIM7600SA-H 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 SIM7600SA-H 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 SIM7600SA-H is in minimum functionality or flight mode, it can return to full functionality by the AT command AT+CFUN=1.

Safety Caution Table 43: 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 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. Forgetting 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.

The modular transmitter must have its own RF shielding. This is intended to ensure that the module does not have to rely upon the shielding provided by the device into which it is installed in order for all modular transmitter emissions to comply with FCC limits. It is also intended to prevent coupling between the RF circuitry of the module and any wires or circuits in the device into which the module is installed. Such coupling may result in non-compliant operation. The physical crystal and tuning capacitors may be located external to the shielded radio elements. 15.212(a)(1)(i)

- YES - NO(*) Details: <example The module contains a metal shield which covers all RF components and circuitry. The shield is located on the top of the board next to antenna connector>

2. The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with FCC requirements under conditions of excessive data rates or over-modulation. 15.212(a)(1)(ii)

- YES - NO(*) Details: <example Data to the modulation circuit is buffered as described in the operational description provided with the application>

3. The modular transmitter must have its own power supply regulation on the module. This is intended to ensure that the module will comply with FCC requirements regardless of the design of the power supplying circuitry in the device into which the module is installed. 15.212(a)(1)(iii)

- YES - NO(*) Details: <example The module contains its own power supply regulation. Please refer to schematic filed with this application>

4. The modular transmitter must comply with the antenna and transmission system requirements of 15.203, 15.204(b), 15.204(c), 15.212(a), and 2.929(b). The antenna must either be permanently attached or employ a unique antenna coupler (at all connections between the module and the antenna, including the cable). The professional installation provision of 15.203 is not applicable to modules but can apply to limited modular approvals under paragraph 15.212(b). 15.212(a)(1)(iv)

- YES - NO(*) Details: <example The module connects to its antenna using an UFL connector which is considered a non-standard connector. A list of antennas tested and approved with this device may be found in users manual provided with the application>

5. The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in Section 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module (see Section 15.27(a)). The length of these lines shall be length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified or commercially available (see Section 15.31(i)). 15.212(a)(1)(v)

- YES - NO(*) Details: <example The module was tested stand-alone as shown in test setup photographs filed with this application>

053019-02a THIS MUST BE SIGNED BY THE APPLICANT/AGENT AND SHOULD BE PLACED ON APPROPRIATE LETTERHEAD Modular Approval Requirement 6. The modular transmitter must be labeled with its own FCC ID number, or use an electron display (see Requirement Met KDB Publication 784748). If using a permanently affixed label with its own FCC ID number, if the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: Contains Transmitter Module FCC ID: XYZMODEL1 or Contains FCC ID:

XYZMODEL1. Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization. If the modular transmitter uses an electronic display of the FCC identification number, the information must be readily accessible and visible on the modular transmitter or on the device in which it is installed. If the module is installed inside another device, then the outside of the device into which the module is installed must display a label referring to the enclosed module. This exterior label can use wording such as the following: Contains FCC certified transmitter module(s). Any similar wording that expresses the same meaning may be used. The user manual must include instructions on how to access the electronic display. A copy of these instructions must be included in the application for equipment authorization. 15.212(a)(1)(vi)

- YES - NO(*) Details: <example There is a label on the module as shown in the labeling exhibit filed with this application. Host specific labeling instructions are shown in the installation manual .filed with this application.>

7. The modular transmitter must comply with all specific rule or operating requirements applicable to the transmitter, including all the conditions provided in the integration instructions by the grantee. A copy of these instructions must be included in the application for equipment authorization. For example, there are very strict operational and timing requirements that must be met before a transmitter is authorized for operation under Section 15.231. For instance, data transmission is prohibited, except for operation under Section 15.231(e), in which case there are separate field strength level and timing requirements. Compliance with these requirements must be assured. 15.212(a)(1)(vii)

- YES - NO(*) Details: <example The module complies with FCC Part 15C requirements. Instructions to the OEM installer are provided in the installation manual filed with this application.>

8. The modular transmitter must comply with any applicable RF exposure requirements. For example, FCC Rules in Sections 2.1091, 2.1093 and specific Sections of Part 15, including 15.319(i), 15.407(f), 15.253(f) and 15.255(g), require that Unlicensed PCS, UNII and millimeter wave devices perform routine environmental evaluation for RF Exposure to demonstrate compliance. In addition, spread spectrum transmitters operating under Section 15.247 are required to address RF Exposure compliance in accordance with Section 15.247(b)(4). Modular transmitters approved under other Sections of Part 15, when necessary, may also need to address certain RF Exposure concerns, typically by providing specific installation and operating instructions for users, installers and other interested parties to ensure compliance. 15.212(a)(1)(viii)

- YES - NO(*) Details: <example The module meets Portable exclusion levels as shown in the RF exposure information filed with this application.>
