摘　　要：介绍了一种小功率毫米波磁控管发射机,阐述了该发射机的系统组成,详细分析了发射机中线性调制器的工作原理。根据磁控管的特点,指出了发射机中线性调制器的设计难点,并详细阐述了相应的解决方法,发射机的测试波形证明了解决方法的有效性。文中还指出了发射机需要改进的一些方面。A low power millimeter-wave magnetron transmitter is introduced in this paper, and its system composition is described. The working principle of linear modulator used in the transmitter is analyzed in detail. According to the characteristics of the mag- netron, the difficulties of designing the linear modulator are discussed, and corresponding solutions are introduced as well. The va- lidity of corresponding solutions is proved by testing the waveforms of the transmitter. Finally, some facets of the transmitter which need to be improved are pointed out.
