Figure 17 roughly describes the current consumption profile of the SARA-G300 and SARA-G310 modules (when
their EXT32K input is not fed by a signal, i.e. left unconnected), or the SARA-G340 and SARA-G350 modules
(‘00’ versions only), or the SARA-U2 modules, when power saving is disabled: the module is registered with the
network, active mode is maintained, and the receiver and the DSP are periodically activated to monitor the
paging channel for paging block reception.

Figure 17: VCC current consumption profile versus time of the SARA-G300 and SARA-G310 modules (when their EXT32K input is
not fed by a signal), or the SARA-G340 and SARA-G350 modules (‘00’ versions only), or the SARA-U2 modules, when registered
with the network, with power saving disabled: the active mode is always held, and the receiver and the DSP are periodically
activated to monitor the paging channel
For detailed modules’ VCC current consumption values in fixed active mode (module registered with 2G / 3G
network with power saving disabled), see the SARA-G3 series Data Sheet [1] and the SARA-U2 series Data
Sheet [2].
