Abstract: A wireless communication device for transceiving signals by using carrier aggregation is provided. The wireless communication device includes a first antenna configured to transmit a first signal to an outside of the wireless communication device or receive a second signal from the outside; a first transmitter connected to the first antenna via a first node and configured to generate the first signal by combining plural transmitting carrier signals received over a plural transmitting carriers; and a first receiver connected to the first antenna via the first node and configured to divide the second signal into a plural receiving carrier signals received over a plural receiving carriers. The first receiver includes a first receiving amplifier commonly connected to a plural carrier receivers configured to amplify the second signal received from the first antenna and to divide the receiving carrier signals, respectively.
