介绍了某高机动雷达集中式固态发射机的新型结构，整个发射设备集成安装于一只方舱内，功放组件和开关电源分机共用静压箱，只要一只风机供风，首次设计应用矩形分配器和合成器。分析了整机结构、安装和连结、冷却设计以及主要分机结构设计特点。该新型结构设计精简了发射机结构，操作维护方便，节省了开机时间，提高了发射机性能。论文最后提出了固态发射机的结构研究方向。对固态发射机设计研究具有一定的参考价值。

This paper describes a new structure of solid state transmitter for a high mobility radar. The transmitter is designed to be assembled in a shelter. Its solid state power amplifier units and switching power supply units share a static pressure box, and cooling air is offered by a fan. Rectangular chaped power divider and combiner are firstly designed and used in the transmitter. The new structure of the transmitter ,assembly and connection,cooling design and its major sub-units are analyzed. The new structural design simplifies the transmitter structure,and is convenient to operate the transmitter. The starting time is shortened and the performance is improved. The trend of development of structure of solid state transmitter are discussed. It may be a valuable ref- erence for solid state transmitter study.
