The importance of power equalization in design and test of transmitter must be regarded seriously, especially in wide-band microwave transmitter with TWT. The performance of transmitter would be lowered because of the unmatch between in-power and frequency-gain-curve of TWT. Some ways are introduced, the disadvantages of the methods in certain transmitter are analyzed, and some useful suggestions to improve the method are given at the same time.
