摘　　要：为了应对国产化需求,设计了一款工作频点在2.7到2.9 GHz的国产氮化镓(GaN)固态雷达发射机。设计的发射系统A、B两路发射机各自可以单独工作。当一路工作出现故障,能够自动切换到另外一路,不会造成中断停机。发射系统的组成部件位于发射机柜和电源机柜里,通过接收来自发射监控系统的控制命令,执行发射监控系统的命令并完成对发射电源及发射组件的控制,完成功率数据、电流电压等数据的采集,同时也将本系统中各主要部件的工作状态和故障信息回馈监控系统。To meet the demand for domestic production,a domestic solid-state gallium nitride(GaN)radar transmitter operating at a frequency in the range of 2.7GHz to 2.9GHz is proposed in this paper.The transmit system is designed with two independent transmit channels,namely channels A and B,which can operate separately.In the event of a failure in one channel,the transmit system can automatically switch to the other channel without causing an interruption.The components of the transmit system are located in the transmitter cabinet and the power supply cabinet.After receiving control commands from the transmit monitoring system,the commands are executed to complete the transmit power supply and transmit component control.In addition,data such as power,current,and voltage values are collected,and the working status and fault information of main components of the system are sent to the monitoring system.
