4.2 Operating conditions

☞ Unless otherwise indicated, all operating condition specifications are at an ambient temperature

of +25 °C.

⚠ Operation beyond the operating conditions is not recommended and extended exposure beyond

them may affect device reliability.

°C/W Thermal characterization parameter ΨM-A = (TM – TA) / PH

proportional to the delta between internal module temperature (TM)

and ambient temperature (TA), due to heat power dissipation (PH), with

the module mounted on a 79 x 62 x 1.41 mm 4-Layer PCB with a high

coverage of copper, in still air conditions

°C/W Thermal characterization parameter ΨM-C =(TM – TC) / PH

proportional to the delta between internal module temperature (TM)

and ambient temperature (TC), due to heat power dissipation (PH), with

the module mounted on a 79 x 62 x 1.41 mm 4-Layer PCB with a high

coverage of copper, with a robust aluminum heat-sink and with forced

air ventilation, i.e. reducing to a value close to 0 °C/W the thermal

resistance from the case of the module to the ambient

9 The voltage has to be above the extended operating range minimum limit for the VCC pin 51 (supply input for the baseband

Power Management Unit and the Transceiver) to switch-on the module and to avoid possible switch-off of the module.

10 Operating with possible slight deviation in RF performance outside normal operating range. The Power Amplifier may not be

fully functional when the voltage drops below the extended operating range minimum limit defined for the VCC pins 52 and 53

(supply input for the internal Power Amplifier).
