For BG950A-GL/BG951A-GL/BG953A-GL, when the module starts up normally, to ensure full functionality, the minimum supply voltage should be higher than 2.2 V. While for BG955A-GL, the minimum supply voltage should be higher than 3.3 V. For every VBAT transition/re-insertion from 0 V, VBAT slew rate < 25 mV/s. To ensure normal module startup, pulling down PWRKEY to turn on the module after VBAT remains stable for 100 ms. 2. After entering PSM or power off mode, it is prohibited to provide any external voltage to the module's I/O ports that are not defined as a wake-up source. 3. Keep all RESERVED pins and unused pins unconnected. 2.6. EVB Kit To help you develop applications with the module, Quectel supplies an evaluation board (UMTS&LTE EVB) with accessories to control or test the module. For more details, see document [1]. BG95xA-GL_Hardware_Design 31 / 102 LPWA Module Series 3 Operating Characteristics 3.1. Operating Modes The table below outlines operating modes of the module. Table 8: Operating Mode Overview Mode Details Normal Operation Extended Idle Mode DRX (e-I-DRX) Idle The module remains registered on the network and is ready to send and receive data. In this mode, the software is active. Connected The module is connected to the network. Its current consumption varies with the network setting and data transfer rate. The module and network may negotiate over non-access stratum signaling the use of e-I-DRX for reducing power consumption while being available for mobile terminated data and/or network originated procedures within a certain delay dependent on the DRX cycle value. Airplane Mode AT+CFUN=4 or W_DISABLE# pin can set the module to airplane mode where the RF function is invalid. Minimum Functionality AT+CFUN=0 can set the module to minimum functionality without removing the power supply. In this mode, both RF function and (U)SIM card are invalid. Sleep Mode Power OFF Mode The module retains the ability to receive paging messages, SMS and TCP/UDP data from the network normally. In this mode, the current consumption is reduced to a low level. The modules power supply is shut down by its power management unit. The software is inactive, the serial interfaces are inaccessible, while the operating voltage of VBAT_BB/RF is still maintained. Power Saving Mode

(PSM) PSM is similar to power-off, but the module remains registered on the network and there is no need to re-attach or re-establish PDN connections. The current consumption is minimized. Recovery Mode The module can burn firmware with an empty serial firmware malfunction. For more details, see Chapter 3.6. flash, or recover from BG95xA-GL_Hardware_Design 32 / 102 LPWA Module Series NOTE In e-I-DRX mode, it is recommended to use the main UART interface for data communication, as the use of USB interface will increase power consumption. 3.2. Airplane Mode When the module enters airplane mode, correlative with RF function will be inaccessible. This mode can be set as follows:

the RF function will be disabled, and all AT commands Hardware:

W_DISABLE# is pulled up by default. Driving it low will make the module enter airplane mode. Software:

AT+CFUN=<fun> provides functionality level choices by setting <fun> to 0, 1 or 4. AT+CFUN=0: Minimum functionality. Both RF and (U)SIM functions are disabled. AT+CFUN=1: Full functionality (default). AT+CFUN=4: Airplane mode (RF function is disabled). NOTE 1. Airplane mode control via W_DISABLE# is disabled in firmware by default. It can be enabled with 2. On BG950A-GL/BG953A-GL/BG955A-GL, AT+QCFG="airplanecontrol". For more details of the command, see document [2]. the execution of AT+CFUN will affect the GNSS function. Since the module does not support concurrent operation of LTE and GNSS, the GNSS function can be used when <fun>=0 or 4, but cannot be used when <fun>=1. 3. On BG951A-GL, the execution of AT+CFUN will not affect the GNSS function. 3.3. Power Saving Mode (PSM) The module minimizes its power consumption by entering PSM. The mode is similar to power-off, but the module remains registered on the network and there is no need to re-attach or re-establish PDN connections. Therefore, in PSM the module cannot immediately respond to user requests. When the module wants to use PSM, it shall request an Active Time value during every Attach and TAU procedure. If the network supports PSM use, it will allocate an Active Time value to the module to confirm BG95xA-GL_Hardware_Design 33 / 102 LPWA Module Series PSM use. If the module wants to change the Active Time value, the module consequently requests the value it wants in the TAU procedure. If PSM is supported by the network, then it can be enabled via AT+QPSMS. In this case, driving PON_TRIG low will set the module to PSM. Any of the following methods can wake up the module from PSM:

Driving PON_TRIG high and keeping it high, will wake up the module from PSM. When the TAU timer expires, the module wakes up from PSM automatically. In this case, the main UART interface is inaccessible until PON_TRIG is pulled up. Driving PWRKEY low to wake up the module from PSM. In this case, the main UART interface is inaccessible until PON_TRIG is pulled up. NOTE 1. PON_TRIG is pulled down by default. 2. PON_TRIG must be pulled up after executing any PSM wake-up event, otherwise the main UART will be inaccessible. In any case, the main UART interface is inaccessible until PON_TRIG is pulled up. 3. See document [3] for details about AT+QPSMS. 3.4. Extended Idle Mode DRX (e-I-DRX) The module (UE) and the network may negotiate over non-access stratum signalling the use of e-I-DRX for reducing its power consumption, while being available for mobile terminating data and/or network originated procedures within a certain delay dependent on the DRX cycle value. Applications that want to use e-I-DRX need to consider specific handling of mobile terminating services or data transfers, and in particular, they need to consider the delay tolerance of mobile terminated data. In order to negotiate the use of e-I-DRX, the UE requests e-I-DRX parameters during attach procedure and RAU/TAU procedure. The EPC may reject or accept the UE request for enabling e-I-DRX. In case the EPC accepts e-I-DRX, the EPC based on operator policies and, if available, the e-I-DRX cycle length value in the subscription data from the HSS, may also provide different values of the e-I-DRX parameters than what was requested by the UE. If the EPC accepts the use of e-I-DRX, the UE applies e-I-DRX based on the received e-I-DRX parameters. If the UE does not receive e-I-DRX parameters in the relevant accept message because the EPC rejected its request or because the request was received by EPC not supporting e-I-DRX, the UE shall apply its regular discontinuous reception. BG95xA-GL_Hardware_Design 34 / 102 LPWA Module Series 3.4.1. e-I-DRX Sleep Mode If e-I-DRX is supported by the network, perform the steps below in sequence to make the module enter e-l-DRX sleep mode, in which case the main UART interface is inaccessible. 1. Send AT+QPSMS=0 to disable the use of PSM. 2. Send AT+CEDRXS=1 to enable the use of e-l-DRX. 3. Send AT+QSCLK=2 to enable sleep mode. 4. Drive MAIN_DTR high. 5. Drive PON_TRIG low. To make the module exit e-l-DRX sleep mode, perform the steps below in sequence. 1. Drive PON_TRIG high. 2. Drive MAIN_DTR low. 3. Send AT+QSCLK=0 to disable sleep mode. 4. Send AT+CEDRXS=0 to disable the use of e-l-DRX mode. 5. Send AT+QPSMS=0 to enable the use of PSM (optional). 3.4.2. e-I-DRX Idle Mode If e-I-DRX is supported by the network, just send AT+CEDRXS=1 to make the module enter e-l-DRX idle mode, or send AT+CEDRXS=0 to make the module exit e-l-DRX idle mode. NOTE See document [3] for details about the above AT commands. 3.5. Sleep Mode The module can reduce its power consumption during the sleep mode. Power saving procedures and sleep mode are outlined in the following sub-sections. 3.5.1. UART Application Scenario If the host communicates with the module via the main UART interface, perform the steps below in sequence to make the module enter the sleep mode, in which case the main UART interface is not accessible. BG95xA-GL_Hardware_Design 35 / 102 LPWA Module Series 1. Send AT+CFUN=0 to set the module to minimum functionality 6. 2. Drive MAIN_DTR low. 3. Execute AT+QSCLK=2 to enable sleep mode. 4. Drive MAIN_DTR high. 5. Drive PON_TRIG low. When the module is in sleep mode, perform the steps below in sequence to make the module exit sleep mode. 1. Drive PON_TRIG high. 2. Drive MAIN_DTR low. 3. Execute AT+QSCLK=0 to disable sleep mode. 4. Send AT+CFUN=1 to set the module to full functionality 6. 5. Drive MAIN_DTR high. The figure illustrates the connection between the module and the host. Figure 8: Sleep Mode Application via UART Interface When the module has a URC to report, MAIN_RI will wake up the host. See Chapter 4.5.4 for details about MAIN_RI behavior. After the module is turned on, MAIN_DTR is internally pulled up by default. AP_READY will detect the sleep state of the host (it can be configured to detect high or low voltage level). See AT+QCFG="apready" in document [2] for details. 6 After setting the module to minimum functionality with AT+CFUN=0, you can test the lowest power consumption of the module after the module enters sleep mode. If you need to keep the RF function on after the module enters sleep mode, there is no need to send any AT+CFUN. BG95xA-GL_Hardware_Design 36 / 102 LPWA Module Series 3.6. Recovery Mode The module features the recovery mode for firmware upgrade in emergency cases. Recovery mode can force the baseband chip of the module to upgrade firmware via the CLI UART interface(s) 7. The following preconditions can set the module to recovery mode. 1. Short-circuit CLI_TXD & CLI_RXD on BG951A-GL, or CLI_TXD2 & CLI_RXD2 on BG950A-GL/

BG953A-GL/BG955A-GL. 2. Drive PWRKEY low to turn on the module. In this case the module will enter recovery mode. 3. After the module enters recovery mode, disconnect CLI_TXD & CLI_RXD, or CLI_TXD2 &

CLI_RXD2. 4. Upgrade firmware via the CLI UART interface(s) 7. NOTE 1. In recovery mode, pin 25 functions as CLI_RTS and pin 26 functions as CLI_CTS, while in other modes they are GPIO pins. 2. Since the baud rate of the UART interface required to download firmware to the baseband chip is 3 Mbps, the flow control pins of the CLI UART interface need to be reserved. Otherwise, you can only download with a 921600 baud rate, which is very slow. It is recommended to reserve the test points of the CLI UART interface, including pin 25, pin 26, pin 94 and pin 95, and keep pin 94 close to pin 95. 3. Ensure that VBAT remains stable for at least 100 ms before pulling down PWRKEY. 3.7. Power Supply 3.7.1. Power Supply Pins The module has two VBAT pins for connection with an external power supply. One VBAT_RF pin for RF part. One VBAT_BB pin for baseband part. Table 9: Power Supply Pin Definition of BG950A-GL/BG951A-GL/BG953A-GL Pin Name Pin No. Description Min. Typ. Max.

NOTE For BG950A-GL/BG951A-GL/BG953A-GL, when the module starts up normally, to ensure full functionality, the minimum supply voltage should be higher than 2.2 V.

Voltage Stability Requirements The power supply range of the BG950A-GL/BG951A-GL/BG953A-GL module is from 2.2 V to 4.35 V. Make sure that the input voltage never drops below 2.2 V. The power supply range of the BG955A-GL module is from 3.3 V to 4.3 V. Make sure that the input voltage never drops below 3.3 V. Figure 9: Power Supply Limits During Burst Transmission BG95xA-GL_Hardware_Design 38 / 102 LPWA Module Series To decrease voltage drop, one bypass capacitor of about 100 F with low ESR and one multi-layer ceramic chip (MLCC) capacitor array for its ultra-low ESR should be used for VBAT_BB & RF respectively. It is recommended to use three ceramic capacitors for composing the MLCC array (100 nF, 33 pF, 10 pF), and place these capacitors close to VBAT pins. The main power supply from an external application must be a single voltage source that can supply power along two star-structured sub paths. The width of VBAT_BB or VBAT_RF trace should be at least 1 mm. In principle, the longer the VBAT trace is, the wider it should be. In addition, to ensure power supply stability, it is necessary to add two high-power TVS components near VBAT_BB and VBAT_RF. The reference circuit of the power supply is shown below. Figure 10: Star Structure of Power Supply Power design for the module is critical to its performance. For BG950A-GL/BG951A-GL/BG953A-GL, the power supply of the module should be able to provide a sufficient current of at least 0.8 A, so it is recommended to select a DC-DC converter chip or an LDO chip with ultra-low leakage current and current output of at least 1.0 A for the power supply design. For BG955A-GL, the power supply design is to be confirmed. 3.7.3. Power Supply Monitoring AT+CBC can be used to monitor the VBAT_BB voltage value. For more details, see document [3]. BG95xA-GL_Hardware_Design 39 / 102 LPWA Module Series 3.8. Turn On 3.8.1. Turn On with PWRKEY Table 11: PWRKEY Pin Definition Pin Name Pin No. I/O Description Comment PWRKEY 15 DI Turn on/off the module Internally pulled up with a 470 k resistor. When the module is in power off mode, driving PWRKEY low for 5001000 ms and then releasing it will turn on the module. It is recommended to use an open drain/collector driver to control PWRKEY. A simple reference design is illustrated in the following figure. Figure 11: Turn On Module With a Driving Circuit Another way to control PWRKEY is with a button. Pressing the button may result in a discharge of static electricity from a finger. Therefore, it is vital to place a TVS component near the button for ESD protection. Figure 12: Turn On Module With a Button BG95xA-GL_Hardware_Design 40 / 102 Drive PON_TRIG high and then drive PWRKEY low after VBAT is stable for 100200 ms, the module will be turned on immediately. The power-up timing is shown below. LPWA Module Series Figure 13: Power-up Timing (After VBAT is Stable for 100200 ms)

. NOTE 1. Ensure that VBAT is stable for 100200 ms before pulling down PWRKEY. 2. Before you turn on the module by driving PWRKEY low for 5001000 ms, drive PON_TRIG high, otherwise, the main UART interface will be inaccessible. Drive PON_TRIG high and then drive PWRKEY low after VBAT is stable for more than 250 ms, the module will be turned on immediately. The power-up timing is shown below. BG95xA-GL_Hardware_Design 41 / 102 LPWA Module Series Figure 14: Power-up Timing (After VBAT is Stable for more than 250 ms) NOTE 1. After VBAT is powered on, it will take about 250 ms for the module to load the internal program. 2. Before the module is turned on by driving PWRKEY low for 5001000 ms, drive PON_TRIG high, otherwise, the main UART interface will be inaccessible. After the module is turned off with the PWRKEY and PON_TRIG solution (see Chapter 3.9.1) or the AT command and PON_TRIG solution (see Chapter 3.9.2), VBAT will keep powered on all the time until the main power supply is disconnected. In this case, driving PON_TRIG high and then driving PWRKEY low will restart the module, and the restart timing is shown below. BG95xA-GL_Hardware_Design 42 / 102 LPWA Module Series Figure 15: Restart Timing 3.9. Turn Off After the module is turned off or enters PSM, do not pull up any I/O pin lest it cause additional power consumption and possibly damage pins on the module. Either of the following methods can be used to turn off the module normally:

Turn off the module via PWRKEY and PON_TRIG. Turn off the module via AT+QPOWD and PON_TRIG. 3.9.1. Turn Off with PWRKEY and PON_TRIG When the module is powered on, drive PWRKEY low for 6501500 ms before releasing it, and then pull down PON_TRIG within 200 ms, after which the module will execute the power-down procedure. The power-down timing is illustrated in the following figure. BG95xA-GL_Hardware_Design 43 / 102 LPWA Module Series Figure 16: Power-down Timing (PWRKEY & PON_TRIG) 3.9.2. Turn Off with AT Command and PON_TRIG Similar to PWRKEY, the module can be turned off safely with AT+QPOWD. After AT+QPOWD is sent, pull down PON_TRIG within 200 ms, and the module will execute the power-down procedure. See document [3] for details about AT+QPOWD. Figure 17: Power-down Timing (AT Command & PON_TRIG) BG95xA-GL_Hardware_Design 44 / 102 LPWA Module Series

. NOTE 1. To avoid internal flash data damage, do not switch off the power supply while the module is working normally. The power supply can be cut off only after the module is shut down with PWRKEY &

PON_TRIG or AT command & PON_TRIG. 2. When turning off the module with AT command, keep PWRKEY at a high level after executing the power-off command. Otherwise, the module will be turned on again after turn-off. 3.10. Reset The module can be reset by driving RESET_N low for at least 100 ms and then releasing it. The RESET_N signal is sensitive to interference, so it is recommended to route the trace as short as possible and surround it with ground. Table 12: RESET_N Pin Definition Pin Name Pin No. RESET_N 17 I/O DI Description Reset the module. Internally pulled up with a 470 k resistor. The recommended circuit is similar to the PWRKEY control circuit. An open drain/collector driver or a button can be used to control RESET_N. Figure 18: Reference Circuit of RESET_N with a Driving Circuit BG95xA-GL_Hardware_Design 45 / 102 LPWA Module Series Figure 19: Reference Circuit of RESET_N with a Button The reset timing is illustrated in the following figure. Figure 20: Reset Timing NOTE 1. Ensure that there is no large capacitance on RESET_N pin. 2. Because PWRKEY and RESET traces are sensitive signal traces, its necessary to surround the traces with ground on that layer and with ground planes above and below, and keep their traces away from each other, so as to reduce interference. BG95xA-GL_Hardware_Design 46 / 102 LPWA Module Series 3.11. PON_TRIG The module provides one PON_TRIG pin. Drive PON_TRIG high and keep it high to wake up the module from PSM. PON_TRIG is pulled down by default. Table 13: Pin Definition of PON_TRIG Pin Name Pin No. I/O Description Comment PON_TRIG 96 DI Used for main UART function control and for entering/exiting e-l-DRX, PSM, sleep or power off mode. 1.8 V power domain. Pulled down by default. PON_TRIG has the following functions:

Makes the module enter or exit e-l-DRX, PSM, sleep or power off mode. Enables/disables the main UART interface communication function. Turns on/off the module. PON_TRIG must be designed to allow for external control. A reference circuit is shown in the following figure. Figure 21: PON_TRIG Reference Circuit 1 In addition, a voltage divider circuit can be used to control PON_RIG. The voltage domain of the external host and the voltage divider resistor should be selected with care. A voltage divider circuit in the 3.3 V host voltage domain is shown in the following figure. BG95xA-GL_Hardware_Design 47 / 102 LPWA Module Series Figure 22: PON_TRIG Reference Circuit 2 NOTE 1. VDD_1V8 is provided by an external LDO. 2. 3. If the hosts voltage domain is not 3.3 V, the value of the voltage divider resistors should be tested according to your actual application. Inside the module, PON_TRIG is connected in series with a diode and connected in parallel with a 10 k pull-down resistor to the ground. Therefore, the actual voltage divider value needs to be measured. The following is a brief description of PON_TRIG use. PON_TRIG is pulled down by default. Before the module is turned on, PON_TRIG must be pulled up. Otherwise, the main UART interface will be inaccessible. When the module is powered on, pull down PON_TRIG within 200 ms after sending AT+QPOWED or driving PWRKEY low, after which the module will execute the power-down procedure. For more details, see Chapter 3.9. After sending AT+QPSMS to enable PSM, driving PON_TRIG low will set the module to PSM. Drive PON_TRIG high and keep it high, the module will wake up from PSM. In this case, PON_TRIG must remain high, otherwise the module will re-enter PSM. Pull down PON_TRIG and keep it low in e-l-DRX, PSM, sleep or power off mode. In other cases, pull up PON_TRIG and keep it high to make sure the main UART is accessible. For details about PON_TRIG use in e-l-DRX and sleep modes, see Chapter 3.4 and Chapter 3.5 respectively. BG95xA-GL_Hardware_Design 48 / 102 LPWA Module Series 4 Application Interfaces 4.1. (U)SIM Interface BG95xA-GL module supports 1.8 V (U)SIM card only. The circuitry of (U)SIM interfaces meet ETSI and IMT-2000 requirements. BG953A-GL supports integrated iSIM. After enabling this function, you do not need to design the (U)SIM interface, which helps to improve the security of the device and reduce the PCB area. For more details about iSIM function, please contact with local network service providers. Table 14: (U)SIM Interface Pin Definition Pin Name Pin No. I/O Description Comment USIM_DET 42 DI

See AT+QSIMDET in document [3] for more details. The following figure illustrates a reference design of (U)SIM interface with an 8-pin (U)SIM card connector. BG95xA-GL_Hardware_Design 49 / 102 LPWA Module Series Figure 23: Reference Circuit of (U)SIM Interface with an 8-Pin (U)SIM Card Connector If (U)SIM card detection function is not needed, keep USIM_DET unconnected. A reference circuit for

(U)SIM interface with a 6-pin (U)SIM card connector is illustrated in the following figure. Figure 24: Reference Circuit of (U)SIM Interface with a 6-Pin (U)SIM Card Connector To enhance the reliability and availability of the (U)SIM card in applications, follow the criteria below in the

(U)SIM circuit design:

Place the (U)SIM card connector as close as possible to the module with a trace shorter than 200 mm. Keep (U)SIM card signals away from RF and power supply traces. BG95xA-GL_Hardware_Design 50 / 102 LPWA Module Series Ensure a short and wide ground trace between the module and the (U)SIM card connector. Keep the ground and USIM_VDD traces at least 0.5 mm wide to maintain the same electric potential. Make sure the bypass capacitor between USIM_VDD and USIM_GND is less than 1 F, and place it as close to the (U)SIM card connector as possible. If the system ground plane is complete, USIM_GND can be directly connected to the system ground. To avoid cross-talk between USIM_DATA and USIM_CLK, keep their traces away from each other and shield them with ground. USIM_RST should also be shielded with ground. To offer good ESD protection, is recommended to add a TVS diode array with parasitic capacitance not exceeding 15 pF. It is recommended to reserve 0 series resistors for the (U)SIM signals of the module to facilitate debugging. The 33 pF capacitors are used for filtering interference of EGSM900. Note that the (U)SIM peripheral circuit should be close to the (U)SIM card connector. it The pull-up resistor on USIM_DATA trace can improve anti-jamming capability, and should be placed close to the (U)SIM card connector. 4.2. USB Interface The module features one integrated USB (Universal Serial Bus) interface that complies with the USB 2.0 specification and supports full speed mode only. This USB interface is used for AT command communication, data transmission, software debugging and firmware upgrade*. The USB interface pin definition is presented in the following table. Table 15: USB Interface Pin Definition Pin Name Pin No. I/O Description Comment USB_VBUS USB_DP 8 9 AI USB connection detect Typ. 5.0 V AIO USB differential data (+) USB_DM 10 AIO USB differential data (-) Compliant with the USB 2.0 standard specification. Requires differential impedance of 90 . It is recommended to reserve test points for debugging and firmware upgrading* in your designs. BG95xA-GL_Hardware_Design 51 / 102 LPWA Module Series Figure 25: Reference Circuit of USB Application To ensure USB data signal integrity, if possible, reserve a 0 resistor on USB_DP and USB_DM traces, respectively. Resistors R1 and R2 should be placed close to the module and to each other. The extra trace stubs must be as short as possible. To meet USB 2.0 specification, comply with the following principles in USB interface designing. It is important to route the USB signal traces as a differential pair with ground. The impedance of the USB differential trace is 90 . Do not route signal traces under crystals, oscillators, magnetic devices, and RF signal traces. It is important to route the USB differential traces in inner layers of the PCB, and surround the traces with ground on that layer and with ground planes above and below. Junction capacitance of the ESD protection components might influence USB data traces, so pay attention to device selection. Typically, the stray capacitance should be less than 2 pF. Keep the ESD protection components as close to the USB connector as possible. If possible, reserve a 0 resistor on USB_DP and USB_DM traces, respectively. For more details about the USB specifications, visit http://www.usb.org/home. NOTE 1. After the module is turned off or enters PSM, do not pull up any USB interface pin lest it cause additional power consumption and potentially damage pins on the module. 2.

See document [3] for more details about these AT commands. The module features 1.8 V UART interfaces. A level-shifting circuit should be used if your application has a 3.3 V UART interface. It is recommended to use a level-shifting chip without internal pull-up. The voltage-level translator TXB0108PWR manufactured by Texas Instruments is recommended. The following figure shows a reference design of the main UART interface:

BG95xA-GL_Hardware_Design 66 / 102 LPWA Module Series 5.1.4. Reference Design It is recommended to reserve a -type matching circuit for better RF performance, and the -type matching components (R1, C1 and C2) should be placed as close to the antenna as possible. The capacitors are not mounted by default. Figure 31: Reference Circuit of Main Antenna Interface 5.2. GNSS BG950A-GL, BG953A-GL and BG955A-GL module features a fully integrated GNSS solution that supports GPS and GLONASS. BG951A-GL module has an independent GNSS solution that supports GPS, GLONASS, BDS, Galileo and QZSS. The modules support standard NMEA 0183 protocol. BG950A-GL, BG953A-GL and BG955A-GL outputs GNSS NMEA sentences via the CLI UART interfaces. BG951A-GL outputs NMEA sentences via the GNSS UART interface. Data update rate for both modules: 110 Hz; 1 Hz by default. GNSS engine is switched off by default. It must be switched on via AT command. BG950A-GL, BG953A-GL and BG955A-GL does not support concurrent operation of LTE and GNSS, while BG951A-GL does. For more details about GNSS engine technology and configurations, see document [4]. 5.2.1.

Reference Design The following is the reference design of GNSS antenna. Figure 32: Reference Design of GNSS Antenna Interface

. NOTE The module is designed with a built-in LNA, and supports passive GNSS antennas only. Active antennas and external LNAs are not supported. BG95xA-GL_Hardware_Design 70 / 102 LPWA Module Series 5.3. Layout Guidelines The following layout guidelines should be taken into account in application designs. Maximize the distance between the GNSS antenna and the main antenna. Digital circuits such as (U)SIM card, USB interface, camera module, display connector, and SD card should be kept away from antennas. Use ground vias around the GNSS trace and sensitive analog signal traces to provide coplanar isolation and protection. Keep 50 characteristic impedance for the ANT_GNSS trace. Refer to Chapter 5.2 for GNSS antenna reference design and antenna installation information. 5.4. RF Routing Guidelines For users PCB, the characteristic impedance of all RF traces should be 50 . The impedance of the RF traces is usually determined by trace width (W), the materials dielectric constant, the height from the reference ground to the signal layer (H), and the space between RF traces and grounds (S). Microstrip or coplanar waveguide is typically used in RF layout to control characteristic impedance. The following are reference designs of microstrip or coplanar waveguides with different PCB structures. Figure 33: Microstrip Design on a 2-Layer PCB BG95xA-GL_Hardware_Design 71 / 102 LPWA Module Series Figure 34: Coplanar Waveguide Design on a 2-Layer PCB Figure 35: Coplanar Waveguide Design on a 4-layer PCB (Layer 3 as Reference Ground) Figure 36: Coplanar Waveguide Design on a 4-Layer PCB (Layer 4 as Reference Ground) To ensure RF performance and reliability, follow the principles below in RF layout design:

BG95xA-GL_Hardware_Design 72 / 102 LPWA Module Series Use an impedance simulation tool to accurately control the characteristic impedance of RF traces to 50 . The GND pins adjacent to RF pins should not be designed as thermal relief pads, and should be fully connected to ground. The distance between the RF pins and the RF connector should be as short as possible and all the right-angle traces should be changed to curved ones. The recommended trace angle is 135. There should be clearance under the signal pin of the antenna connector or solder joint. The reference ground of RF traces should be complete. Meanwhile, adding some ground vias around RF traces and the reference ground could help to improve RF performance. The distance between the ground vias and RF traces should be at least two times the width of RF signal traces (2 W). Keep RF traces away from interference sources, and avoid intersection and paralleling between traces on adjacent layers. For more details about RF layout, see document [5]. 5.5.

Top and Bottom Views LPWA Module Series Figure 43: Top & Bottom Views of BG95xA-GL NOTE Images above are for illustrative purposes only and may differ from the actual module. For authentic appearance and label, please refer to the module received from Quectel. BG95xA-GL_Hardware_Design 93 / 102 LPWA Module Series 9 Storage, Manufacturing & Packaging 9.1. Storage Conditions The module is provided with vacuum-sealed packaging. MSL of the module is rated as 3. The storage requirements are shown below. 1. Recommended Storage Condition: the temperature should be 23 5 C and the relative humidity should be 3560 %. 2. Shelf life (in a vacuum-sealed packaging): 12 months in Recommended Storage Condition. 3. Floor life: 168 hours 19 in a factory where the temperature is 23 5 C and relative humidity is below 60 %. After the vacuum-sealed packaging is removed, the module must be processed in reflow soldering or other high-temperature operations within 168 hours. Otherwise, the module should be stored in an environment where the relative humidity is less than 10 % (e.g., a dry cabinet). 4. The module should be pre-baked to avoid blistering, cracks and inner-layer separation in PCB under the following circumstances:

The module is not stored in Recommended Storage Condition;

Violation of the third requirement mentioned above;

Vacuum-sealed packaging is broken, or the packaging has been removed for over 24 hours;

Before module repairing. 5. If needed, the pre-baking should follow the requirements below:

The module should be baked for 8 hours at 120 5 C;

The module must be soldered to PCB within 24 hours after the baking, otherwise it should be put in a dry environment such as in a dry cabinet. 19 This floor life is only applicable when the environment conforms to IPC/JEDEC J-STD-033. It is recommended to start the solder reflow process within 24 hours after the package is removed if the temperature and moisture do not conform to, or are not sure to conform to IPC/JEDEC J-STD-033. And do not remove the packages of tremendous modules if they are not ready for soldering. BG95xA-GL_Hardware_Design 94 / 102 LPWA Module Series NOTE 1. To avoid blistering, layer separation and other soldering issues, extended exposure of the module to the air is forbidden. 2. Take out the module from the package and put it on high-temperature-resistant fixtures before baking. All modules must be soldered to PCB within 24 hours of the baking, otherwise put them in the drying oven. If shorter baking time is desired, see IPC/JEDEC J-STD-033 for the baking procedure. 3. Pay attention to ESD protection, such as wearing anti-static gloves, when touching the modules. 9.2. Manufacturing and Soldering Push the squeegee to apply the solder paste on the stencil surface, thus making the paste fill the stencil openings and then penetrate the PCB. Apply proper force on the squeegee to produce a clean stencil surface on a single pass. To guarantee module soldering quality, 0.130.15 mm stencil thickness for the module is recommended. For more details, see document [6]. The peak reflow temperature should be 235246 C, with 246 C as the absolute maximum reflow temperature. To avoid module damage caused by repeated heating, it is strongly recommended that the module should be mounted only after reflow soldering of the other side of PCB has been completed. The recommended reflow soldering thermal profile (lead-free reflow soldering) and related parameters are shown below.

-1.5 to 3 C/s 1 1. If the module requires conformal coating, DO NOT use any coating material that may chemically react with the PCB or shielding cover, and prevent the coating material from flowing into the module. 2. Avoid using ultrasonic technology for module cleaning since it can damage crystals inside the module. 3. Due to the SMT process complexity, please contact Quectel Technical Support in advance regarding any situation that you are not sure about, or any process (e.g., selective soldering, ultrasonic soldering) that is not mentioned in document [6]. 9.3.
