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