Abstract:

A fast method for suppressing transmitter carrier leakage is proposed to obtain more purified spectrum and suppress carrier leakage and useless side bank leakage.The cause and the suppression principle of carrier leakage are analyzed,and the method of using the parabolic two element method is put forward.This method can effectively control the transmitter carrier leakage,greatly improve the suppression efficiency,eliminate all kinds of adverse effects caused by the carrier leakage,improve the testing efficiency and save the test cost.The experiment proves that the method is correct and effective.
