The present invention relates to a real-time wireless signal amplification repeater. The real-time wireless signal amplification repeater includes: a band pass filter which detects a signal in a used frequency band except the spurious wave generated by the interference of an external input signal input through an antenna from the outside and an internal amplification signal generated by amplifying the external input signal; a coupler which separates the external input signal and the internal amplification signal passing through the band pass filter; a mixer which detects the external input signal passing through the coupler; a signal amplification processing unit which executes an amplifying process for the difference value of the set limit power and maximum power in an amplifier when the maximum power regarding intensity of the signals of multiple reception channels included in the detected external input signal is determined to be lower than the amplification power; and a phase delay unit which delays the phase internal amplification signal in order to make the phase difference of the internal amplification signal and the external input signal detected in the mixer be 360 degrees. The present invention amplifies digital communication signals which use the frequency modulation method in a specific band and are received through the antenna of the repeater, with a limited output in accordance with the conditions in order to retransmit the digital communication signals at the same frequency through the same antenna. |
