Figure 4-1 shows how the output power of the RFD900ux varies with supply voltage when the output
power is set to +30dBm.

Figure 4-2 shows how the current through the RFD900ux varies with the transmit power level. The
current during transmission is shown by the ‘High Level’ plot and that during receive mode is shown
by the ‘Low Level’ plot.
