Hi Mohamed, The transmit power of the cc2420 (and any 802.15.4 chip) is really low: 0dBm=1mW (about 0.3mA at 3.3V). However a received packet needs much more signal processing then a transmitted one (check the block diagram: http://www.ti.com/general/docs/datasheetdiagram.tsp?diagramId=SWRS041B&genericPartNumber=CC2420&isFunctional=Y&isFunctional=Y).
