Taking advantage of high peak power and high efficiency of vacuum tube, the high-power transmitting module based on X band traveling wave tube is studied. The key technologies such as the design of 8-channel transmitting module, miniaturized packaging of high-voltage module and amplitude phase consistency control are introduced in this paper and an 8-channel traveling wave tube transmitting module is developed based on these technologies. The module adopts an integrated design method that uses a set of power supply to simultaneously power 8 tubes, which improves the power density of the module, reduces the volume of the transmitting component, and meets the requirements of the radar array. By adjusting the amplitude and phase consistency of each channel of the transmitting module, an 8-channel power combining test is conducted. The test data achieves the expected results and the feasibility of the proposed technology is further verified. The module is a new type of traveling wave tube amplifier transmitting module, which has a small size, high power density and relatively low price, and provides a new solution for phased array radar transmitting unit.
