Thanks Andre, I knew already about these figures, but I am interesting, in the case of CC2420, know how the power is used, i.e. % goes amplifier, filtering, DAC, despreding, PLL, etc trying to understand the sources or power consumption in reception.

The more robust modelations make a price on the energy waste at reception.
