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. 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

20 uA www.simcom.com 26 / 75 SIM7600G-H User manual 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, more than 300uF capacitors are recommended .Otherwise users must use a total of 1000uF capacitors typically, in order to avoid of the voltage drop 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. Recommend Bead for vbat filter are BLM21PG300SN1D and MPZ2012S221A Figure 6: Power supply application circuit In addition, in order to guard for over voltage protection, it is suggested to use TVS. NOTE user could only power pin 62, 63 or only power pin 38, 39, for these pins are connected inside the MODULE. www.simcom.com 27 / 75 SIM7600G-H User manual Table 7: Recommended TVS list No. Manufacturer Part Number Power dissipation Package 1 2 3 4 5*

<0.5dB

<0.9dB

<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 35: 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 MODULE and antenna must be controlled in 50. Figure 36: Antenna matching circuit (AUX_ANT) In above figure, R3, C3, C4 and R4 are used for auxiliary antenna matching. By default, the R3, R4 are 0resistors, and the C3, C4 are reserved for tuning. D2 is a TVS for ESD protection, and it is optional for users according to application environment. www.simcom.com 55 / 75 Two TVS are recommended in the table below. Table 30: Recommended TVS Package 0201 0402 NOTE Part Number LXES03AAA1-154 LXES15AAA1-153 SIM7600G-H User manual Vender Murata Murata SIMCom suggests the LTE auxiliary antenna to be kept on, since there are many high bands in the designing of LTE-TDD, such as 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.

[25]. 4.3. GNSS MODULE merges GNSS (GPS/GLONASS/BD) 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/-159 dBmBD Cold-start sensitivity: -148 dBm Accuracy (Open Sky): 2.5m (CEP50) TTFF (Open Sky) : Hot start <1s, Cold start<35s Receiver Type: 16-channel, C/A Code GPS L1 Frequency: 1575.421.023MHz GLONASS: 1597.5~1605.8 MHz BD: 1559.05~1563.14 MHz Update rate: Default 1 Hz GNSS data format: NMEA-0183 GNSS Current consumption : 100mA (GSM/UMTS/LTE Sleep ,in total on VBAT pins) GNSS antenna: Passive/Active antenna NOTE www.simcom.com 56 / 75 SIM7600G-H User manual 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 MODULE. If using a passive antenna, an external LNA is a must to get better performance. The following figures are the reference circuits. Figure 37: Active antenna circuit Figure 38: Passive antenna circuit (Default) 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 www.simcom.com 57 / 75 SIM7600G-H User manual not working. NOTE 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 MODULE in proper operating mode by AT command. Please refer to related documents for details. MODULE 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

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 is used close to TV sets, radios, computers or other electric equipment. it 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. www.simcom.com 75 / 75 Antenna requirements 1. Antenna List:
