LZT 123 7607 R1B
Current Consumption at Standard Operation
Notes! Power Down Mode: DC power is applied but the GT47 is switched OFF.
Standby Mode: The module is switched ON and camped on to the
network. No call in progress.
Talk Mode: The module is switched ON and a voice/data call is in
progress.
The power consumption during transmission in Talk Mode is measured at
maximum transmitted power.
The power consumption in Standby Mode is measured at the maximum
paging rate (Paging Rate 2).
Current Consumption with external +4.8V Supply Active
For the following calculations it was assumed that the external +4.8V load
is 70mA.
Note! These tables do not include the power consumption associated with any
drive current supplied via further GT47 outputs, e.g. OUT-1 or OUT-2.
