2.5 Current consumption

The current consumption figures of the Hiberband modem are specified in table 6.

Table 6: Hiberband modem current consumption

When designing the application power supply, attention must be paid to the transient behaviour of the Hiberband

modem current consumption when the transmitter power amplifier is turned on. In particular, the Hiberband

transmission burst current consumption (figure 2) pattern needs to be taken into account. For comparison

purposes, the current consumption for transmission of a continuous wave is shown in figure 3.

Figure 2: Hiberband transmission burst current consumption

Figure 3: Hiberband modem transmitter current consumption (continuous wave)

Both patterns were measured with +30 dBm transmission power.
