2.7 Module application circuit
2.7.1 Active antenna applications (modules provide antenna power supply, antenna detection and short circuit protection)

Passive antenna applications (add LNA in module RF_IN input)
2.8 Considerations
In order to make full use of excellent performance of the module, users need to pay attention to the following points when using this module:
Use low ripple LDO power supply, control the ripple within 50mVpp
Vicinity of module should be no other high frequency and large amplitude digital signal. All modules are filled with ground wire.
The RF input pin should be as close as possible to the wireless interface module, and be attention to impedance matching of 50 ohm.
The module
has the active antenna access, pull out, short circuit detection circuit itself, the antenna power supply current limit (50mA), play the role of protection while in the antenna accident short circuit.
When the above 3 kinds of antenna port state change, you can get information from the serial port. Such as:
$GPTXT, 01, 01, 01, ANTENNA SHORT*63
$GPTXT, 01, 01, 01, ANTENNA OPEN*25
$GPTXT, 01, 01, 01, ANTENNA OK*35
3. Test and Authentication of Reliable
3.1 RoSH Authentication
ATGM336H-5N series modules all meet the RoSH certification.
4. Delivery and Welding of Module
4.1 Package of Module
ATGM332D-5N series of modules use vacuum tape packaging, with moisture, anti-static and other characteristics, the process of using is compatible with the industry's major patch machine. Package method is 1000 piece each set.


4.2 Transfer and storage of module
4.2.1 Moisture Level
Moisture Sensitivity Level MSL): 4
As for MSL, please refer to IPC/JEDEC J-STD-020 Standard
4.2.2 Reflow profile

Attention:
1. Adjust the balance time to ensure a reasonable treatment of gas when solder paste melt. It can increase the balanced time if there is a lot of space on PCBA.
2.Because the product will be placed in the weld zones(temperature will be over 180ºC),in order to prevent component and bottom plate from damaging, the placing time should be as short as possible.
Some important characteristic of curve:
Rising speed=1~4ºC/sec, 25ºC to 150ºC on average
Preheat temperature=140ºC to 150ºC,60sec ~ 90sec
Temperature fluctuation= 225ºC to 250ºC, about 30sec
Decent speed=2~6ºC/sec, to 183ºC, about 15sec
Total time= about 300sec

4.2.3 Electrostatic protection
ATGM332D-5N series module is one kind of electric sensitive elements. Regular electrostatic contact will cause the unexpected damage of module. Except standard ESD protection requirements, those following points should be followed:
The first position of module should always be PCB GND unless PCB GND has been connected to ground. Connect GND to ground first before signal lines. Do not touch charging capacity when contacting RF circuit, also please get away from devise and equipment which could generate static electricity such as dielectric antenna, coaxial cable and electric soldering iron, etc. Don't not touch medium exposed part of antenna to prevent RFIN from charge discharge. As for the exposed antenna, add ESD protection circuit. Please use non electrostatic gun when welding connectors connected with RFIN and antenna. 5.1 Module label
