Abstract: A radio communication device (100) having a receiver (110) for receiving a radio frequency (RF) signal includes first and second batteries (140, 175) for generating first and second voltages, respectively, wherein the second voltage is greater than the first voltage.

Other processing circuitry (115, 120) within the radio communication device (100) receives the third voltage and is powered thereby during the first time period when the receiver (110) is disabled from receiving the RF signal. The other processing circuitry (115, 120) receives the second voltage and is powered thereby during a second time period when the receiver (110) is enabled for reception of the RF signal.
