PURPOSE: A short distance wireless transceiver capable of using multiband is provided to normally transmit and receive the multiband signal with sliming size of the wireless transceiver by applying a common antenna capable of transmitting and receiving the multiband signal. CONSTITUTION: An antenna(100) transmits and receives the wireless communication signal of multiband. An RF signal preprocess unit(110) passes through only the signal of the selection band, processes the radio frequency signal received according to the transceiver path set and RF processes the signal to be transmitted. A modulator/demodulator unit(120) modulates/demodulates a transmitted/received signal according to modulation/demodulation method for the short distance wireless communication. A baseband processing unit(130) processes the signal of multiband into bandwidth baseband signal.
