1)
” When the module works within the temperature range, the deviations from the RF specification
may occur. For example, the frequency error or the phase error would increase.
2. The maximum surface temperature may be up to 100ºC when module works at 85ºC ambient
temperature.
6.4. Current Consumption
The values of current consumption are shown below.
