Abstract: An apparatus and a method for compensating for carrier leakage in a quadrature modulation system are provided to realize a carrier leakage compensating apparatus simply by using various quadrature modulators, thereby suppressing carrier leakage. A quadrature modulation unit(300) outputs a leakage carrier signal about an in-phase path and a quadrature phase path. The in-phase path and the quadrature phase path are made by the first and second bias voltages and difference between the first and second control voltages. A coupler(500) extracts a partial leakage carrier signal among the outputted leakage carrier signals. A detection unit(600) detects a size of the extracted leakage carrier signal to measure a carrier leakage amount. The detection unit converts the leakage carrier signal into a DC signal. Controllers(900,910) output the first and second control voltages by comparing the DC signal with the first and second reference voltages.
