Functional Diagram - Quectel EG12 Series Hardware Design

Firmware Upgrade
RoHS
NOTES
1. "*" means under development.
1)
2. Within operating temperature range, the module is 3GPP compliant.
2)
3. Within extended temperature range, proper mounting, heating sinks and active cooling may be
required to make certain functions of the module such as voice, SMS, data transmission, emergency
call to be realized. Only one or more parameters like Pout might reduce in their value and exceed the
specified tolerances. When the temperature returns to normal operating temperature levels, the
module will meet 3GPP specifications again.
