In order to cope with the demand of foreign chip ban and domestic radar,a domestic gallium nitride(GaN)solid state radar transmitter is designed at 1.2 GHZ～1.4 GHz.The domestic GaN power module is used to minimize the transmission system and reduce the weight of the components.Strengthen the high reliability and maintenance convenience design of the equipment,further improve the online test function of GaN power module,so that the product has high reliability and perfect radar fault diagnosis function.The monitoring,detection and display functions of the system are added,and all the working state signals are transmitted to the main monitoring,so that all the working states of the system can be displayed on the terminal,so that the operators can check the various working parameters of the transmitting system and judge the working state of the transmitter through the terminal interface.In terms of suppressing the second harmonic suppression by the harmonic filter,the test results show that the second harmonic of the output signal of the transmitting system is less than or equal to-66dB.
