Vehicular radar and high power airborne radar have strict demands on volume and weight of vacuum tube transmitter, so it is necessary to miniaturize radar transmitter. Miniaturization design of a high power multi-beam klystron transmitter is introduced. The main key performance indicators and the system constitution are presented. The emphasis is put on the key technologies of high power density high voltage power supply, miniaturization of solid state modulator, the integrated design method of high voltage power supply and the thermal design of final module. Experiments indicate that the miniaturization of transmitter meets the expected design requirements. The application and prospect of the transmitter is discussed.
