PROBLEM TO BE SOLVED: To provide an apparatus and method for branching a signal for a mobile communication terminal by blocking interrupts between different bands using an electric switch between input terminals of an antenna and a transceiver. SOLUTION: The method of this invention includes: a step of electrically switching an RF signal received by a band-selecting signal of a CPU, branching the signal to a port corresponding to a respective band, outputting the signal to a terminal of the transceiver to branch the signal of the mobile communication terminal, and receiving the input of the RF signal through the antenna; and further a step of outputting the band-selecting signal of the CPU corresponding to the received RF signal to the electric switch.
