xbee power consumption problem

Hi, how to calculate the power consumption of the xbee right?
it says 1mW output (+0dBm) but the transmit current is 45mA (@3.3V) .
Is not that output consumption equals 45m*3.3V? Where am I wrong?

thanks.

The output power of the signal is not directly related to how much current the XBee uses when outputting the signal. The output power is 1mW. The power required to produce that output is 0.045 * 3.3 = 0.1475 W (or 148 mW).
