Abstract:

The transmitter,as the core component of the deep space exploration system,must provide high power radio frequency energy for the system,to detect the distant targets.The outstanding advantage of the klystron transmitter lies in its capability of high power output and operation at the X band with high efficiency and low cost of development,which are not characteristic of the solid-state transmitter.Therefore,the development of high conversion efficiency,high reliability and high output power klystron transmitter is the key to the success of deep space exploration.This paper introduces the development of X band continuous wave (CW) klystron transmitter and reviews the current situation and development trend Using,the development of ultra high power CW klystron transmitter is discussed based on existing technology to provide support for China's deep space exploration.
