LTE Standard Module Series
EC200U_Series_Hardware_Design 12 / 94
2.3. Functional Diagram
The following figure shows a block diagram of EC200U series and illustrates the major functional parts.
⚫ Power management
⚫ Baseband
⚫ Flash
⚫ Radio frequency
⚫ Peripheral interfaces
7
GNSS function is optional.
8
Within operating temperature range, the module is 3GPP compliant.
9
Within the extended temperature range, the module remains the ability to establish and maintain functions such as voice,
SMS, data transmission, etc., without any unrecoverable malfunction. Radio spectrum and radio network are not influenced,
while one or more specifications, such as Pout, may exceed the specified tolerances of 3GPP. When the temperature
returns to the operating temperature range, the module meets 3GPP specifications again.
