GSM signals can interfere with audio through coupling and conduction. Users can filter out coupling interference by adding 33pF and 10pF capacitors to the audio path. The 33pF capacitor mainly filters out the interference in the GSM900 frequency band, and the 10pF capacitor mainly filters out the interference in the DCS1800 frequency band. The coupling interference of TDD has a lot to do with the user's PCB design.

In some cases, the TDD in the 900 frequency band is more serious, and in some cases, the TDD interference in the 1800 frequency band is serious. Therefore, users can select the required filter capacitors according to the actual test results, and sometimes even do not need to paste filter capacitors.

The GSM antenna is the main source of coupling interference for TDD, so users should pay attention to keeping the audio trace away from the RF antenna and VBAT during PCB layout and routing. It is best to place a set of audio filter capacitors close to the module end, and another set close to the interface end. The audio output should be routed according to the differential signal rules.

www.simcom.com

30 / 63

A7602E-H&A7608SA-H Mini-PCle module Hardware Design V1.01

The conducted interference is mainly caused by the voltage drop of VBAT. If the Audio PA is directly powered by VBAT, it is easier to hear the "squeak" sound at the output end of the SPK. Therefore, it is best to connect the input end of the Audio PA in parallel in the schematic design. Some bulk capacitors and ferrite beads in series.

TDD and GND are also closely related. If the GND is not handled properly, many high-frequency interference signals will interfere with the MIC and Speaker through bypass capacitors and other devices.

Therefore, it is very important for the user to ensure the good performance of the GND during the PCB design stage.

Figure 20: Microphone interface configuration

NOTE

1. Module has integrated MIC bias circuit. There is no need to pull the MICP and MICN up to the external power, just connect it to microphone. MICP and MICN must be differential lines.

A7602E-H&A7608SA-H Mini-PCle module Hardware Design V1.01

The following figure is the reference circuits.

Figure 28: Active Antenna Circuit

Figure 29: Passive antenna circuit

In above two figures, the component C1 is used for DC isolation, and L1 is used for antenna matching, the value of it can be obtained after the antenna tuning usually, so the default value is NC. In active antenna circuit, users also can use an external LDO/DCDC to provide VDD voltage which value should be taken according to active antenna characteristic, and VDD can be shut down to avoid consuming additional current when not being used.

Users can adopt an active antenna as GNSS signal receiver. The following is the reference circuit.

This command is used to control the power supply of the built-in LNA of the active antenna.

NOTE

1.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.

2.If customer need save the power when the GNSS function is disabled, then customer should design a switch circuit to cut off the active antenna power to get a lower power consumption.

4.3.3 GNSS Operate Mode

The module supports A-GPS, A-GPS includes mobile-assisted and mobile-based mode.

In mobile-assisted mode, when a request for position location is issued, available network information is provided to the location server (e.g. Cell-ID) and assistance is requested from the location server. The location server sends the assistance information to the handset. The handset/mobile unit measures the

GNSS observables and provides the GNSS measurements along with available network data (that is appropriate for the given air interface technology) to the location server. The location server then calculates the position location and returns results to the requesting entity.

www.simcom.com

44 / 63

A7602E-H&A7608SA-H Mini-PCle module Hardware Design V1.01

In mobile-based mode, the assistant data provided by the location server encompasses not only the information required to assist the handset in measuring the satellite signals, but also the information required to calculate the handset’s position. Therefore, rather than provide the GNSS measurements and available network data back to the location server, the mobile calculates the location on the handset and passes the result to the requesting entity.

In standalone (autonomous) mode, the handset demodulates the data directly from the GNSS satellites.

This mode has some reduced cold-start sensitivity, and a longer time to first fix as compared to the assisted modes. However, it requires no server interaction and works out of network coverage.

This combination of GNSS measurements and available network information provides:

●

High-sensitivity solution that works in all terrains: Indoor, outdoor, urban, and rural

High availability that is enabled by using both satellite and network information

Therefore, while network solutions typically perform poorly in rural areas and areas of poor cell geometry/density, and while unassisted, GNSS-only solutions typically perform poorly indoors. The module’s GNSS solution provides optimal time to fix, accuracy, sensitivity, availability, and reduced network utilization in both of these environments, depending on the given condition.

GNSS can be used by NMEA port. User can select NMEA as output through 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 module in proper operating mode by AT command. Please refer to related document for details. Module can also get position location information through AT directly.

Minimum functionality mode

Function

In this case, the current consumption of module will be reduced to the minimal level and the module can still receive paging message, call, SMS and TCP/UDP.

Software is active. 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.

AT command “AT+CFUN=0” AT+CSCLK=1 can be used to set the module to a minimum functionality mode without removing the 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.

Customer could cut off the VCC to power off module.

5.3.2 Power saving mode

The module has two power saving modes: minimum functionality mode and sleep mode. In which module will achieve lower power consumption for power saving.

5.3.3 Sleep mode

In sleep mode, the current consumption of module will be reduced to the minimal level, and module can still receive paging message, SMS, TCP and UDP.

The module has two sleep modes, the corresponding floor current in each mode is different, and the two www.simcom.com

47 / 63

A7602E-H&A7608SA-H Mini-PCle module Hardware Design V1.01

modes can be switched by AT command

●

AT*CPCBTYPE=0,0: floor current [email protected](Default) (CFUN=0) ；

AT*CPCBTYPE=0,1: floor current [email protected](CFUN=0).

There are three steps to let the module enter into the sleep mode:

●

Execute AT command AT+CVAUXS=0 to power off the antenna;

Execute AT command

AT+CGNSSPWR=0, AT+CGNSSTST=0

to turn

off the GPS power supply;

Execute AT command

AT+CSCLK=1

to enable the sleep mode

;

The following is a detailed explanation of the two sleep modes

5.3.3.1 USB suspend mode

When the host supports the USB suspend function, this mode can be used for hibernation.

In this mode, the USB power supply will always supply power. At this time, the module can be hibernated by controlling the host to hibernate. When the host exits the sleep mode, the module also exits the sleep mode, and the sleep current in this mode is about 2.5mA. The following is a flow chart of module sleep and wake-up in this mode www.simcom.com

A7602E-H&A7608SA-H Mini-PCle module Hardware Design V1.01

Figure 31: Module wakes up(USB suspend mode)

5.3.3.2 USB voltage controllable mode

In this mode, when the module is working normally, the USB power supply keeps supplying power.

When the module sleeps, the USB power supply is disconnected. At this time, the module can be hibernated by controlling the host to sleep. However, when the module wakes up, it needs to pull down DTR externally, and the module will wake up after the running host exits dormancy. The sleep current in this mode is about 1.5mA.

The corresponding sleep currents in the two different modes are different. Customers can choose the appropriate sleep mode according to actual needs.

Others hardware and software conditions must be satisfied together in order to let module enter into sleep mode:

1. UART condition

2. Software condition

NOTE

Before designing, pay attention to how to realize sleeping/waking function and refer to Document [22] for more details.

A7602E-H&A7608SA-H Mini-PCle module Hardware Design V1.01

5.3.4 Minimum functionality 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: Disable RF function of the module (Flight mode)

The module has been set to minimum functionality mode, module will firstly enter sleep mode, then the RF function and USIM card function will be closed. In this case, the serial port is still accessible, but RF function or USIM card will be unavailable. When module is in minimum functionality or flight mode, it can return to full functionality by the AT command “AT+CFUN=1”.

7.4 Safety Caution

Table 40: 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.
