An apparatus and a method for amplifying power by controlling delay in a wireless communication system are provided to increase the accuracy of time arrangement and prevent the distortion of the spectrum performance of a final RF signal. A signal converter split a baseband signal into an envelop signal and a phase modulation signal. By using the extraction of a correlation coefficient and an interpolation method, a delay difference measurement unit(110) measures the delay difference among signal paths. According to the measured delay difference, delay controllers(104,105) set up the delay for a signal path of which delay is small as clock period unit. In addition, the delay controllers set up the delay for a signal path of which delay is large as the rest delay difference.
