29 / 43 page  SARA-R4 series - Data sheet UBX-16024152 - R18 Electrical specifications Page 29 of 43 4.3 Parameters for ATEX applications This section provides useful parameters and information to integrate SARA-R4 series modules in applications intended for use in areas with potentially explosive atmospheres (ATEX), describing: Total internal capacitance and inductance of the modules (see Table 25) Maximum RF output power and voltage at the antenna (ANT) pin of the modules (see Table 26) ☞ Any specific applicable requirement for the implementation of the apparatus integrating the SARA-R4 series modules, intended for use in potentially explosive atmospheres, must be fulfilled according to the exact applicable standards: check the detailed requisites on the pertinent normative for the application, as for example the IEC 60079-0 [13], IEC 60079-11 [14], and IEC 60079-26 [15] standards. ☞ The certification of the application device that integrates a SARA-R4 series module and the compliance of the application device with all the applicable certification schemes, directives and standards required for use in potentially explosive atmospheres are the sole responsibility of the application device manufacturer. Table 25 describes the maximum total internal capacitance and the maximum total internal inductance, considering internal parts tolerance, of the SARA-R4 series modules. Module Parameter Description Value Unit SARA-R404M Ci Maximum total internal capacitance 510 µ F Li Maximum total internal inductance 9.2 µ H SARA-R410M, SARA-N410 Ci Maximum total internal capacitance 504 µ F Li Maximum total internal inductance 9.3 µ H SARA-R412M Ci Maximum total internal capacitance 507 µ F Li Maximum total internal inductance 9.4 µ H Table 25: SARA-R4 series maximum total internal capacitance and maximum total internal inductance Table 26 describes the maximum RF output power transmitted by SARA-R4 series modules from the antenna (ANT) pin as Power Class 3 User Equipment for the LTE Cat M1 / NB1 bands and/or as Power Class 4 Mobile Stations for GSM 850 / E-GSM 900 bands. Module Parameter Description Value Unit SARA-R404M ANT Pout Maximum RF output power from ANT pin 25.00 dBm SARA-R410M ANT Pout Maximum RF output power from ANT pin 25.00 dBm SARA-N410 ANT Pout Maximum RF output power from ANT pin 25.00 dBm SARA-R412M ANT Pout Maximum RF output power from ANT pin 33.00 dBm Table 26: SARA-R4 series maximum RF output power ☞ The SARA-R4 series modules do not contain internal blocks that increase the input voltage (such as step-up, duplicators, or boosters) except for the antenna (ANT) pin, for which the maximum RF output power shown in Table 26. |
