The value of the total transmission mode current is the sum of I
DD(RX/TX)(tot)
+ I
DD(PAMP)
.
Frequency range corresponding to the EN50065-1 band. However, the modem can operate at any lower oscillator frequency.
The minimum value can be improved by using an external amplifier; see application diagrams
Figure 19
and
Figure 20.
