1. An apparatus configured to transmit power and data, using mutual resonance, the apparatus comprising:

  • a power transmitter configured to wirelessly transmit power to a device by using a first frequency, wherein the power transmitter comprises a first source resonator configured to transmit the power to a first target resonator of the device, wherein the first target resonator of the device resonates at the first frequency;

    a communication unit configured to transmit data to the device by using a second frequency, based on mutual resonance between the communication unit and the device, wherein the communication unit comprises a second source resonator configured to transmit the data to a second target resonator of the device, wherein the second target resonator of the device resonates at the second frequency, and wherein the second source resonator has an overlapped area with the first source resonator;

    a controller configured to determine a charging state of the device, based on the data received from the device, and to control an amount of the power, based on the charging state; and

    a filter configured to block a signal of the first frequency or the second frequency, to prevent a magnetic field from being induced between the first source resonator and the second source resonator.
