With the rapid development of modern radar technology for the requirements of the transmitter is also far more than in the earlier simple functional requirements , but the demanding requirements for the performance of the transmitter , a modern radar transmitter , not only on the requirements of the basic indicator of the band , the output power , signal form etc. , there are proposed based on the performance requirements of the radar system , such as frequency stability indicator requirements , more importantly, is the comprehensive realization of the various indicators of the performance indicators . The nineties of the last century, multi- beam klystron technology introduced into China from Russia , followed by the efforts of the relevant research institutions in China to achieve localization , Since then, the multi - beam klystron with its excellent performance in the radar transmitter widely used multi- beam klystron as a new type of microwave devices , represents the development direction of the radar transmitter . In this thesis, a model machine airborne PD radar transmitter system is the basis of practice , research the technology of multi-beam klystron transmitter , and the study focused on the implementation of a high performance multi- beam klystron transmitter aspects. The paper first introduces the domestic and international multi- beam klystron Research and its working principle and performance indicators , to discuss the status of the multi-beam klystron transmitter , and then study the technical indicators of a multi-beam klystron transmitter and key technical analysis conducted in-depth research and practice , with a focus on the causes and control of multi- beam klystron transmitter phase noise , which provides the technical foundation for the design of high-performance multi-beam klystron transmitter in Based on this, the angle of the papers from the engineering practice in-depth discussion of the high-performance multi-beam klystron transmitter system and circuit design , including the system amplification chain , high - voltage power supply , modulator, the auxiliary power supply , and other aspects of the design , and finally also provides a engineering prototype test data .
