Design of a W-Band High Power Transmitter

Millimeter wave radar has excellence in detecting the formation and development of cloud,fog and rain.It is a significant means for knowing physics course of weather.The design technique and process of a W-band high power transmitter used in rain cloud radar are introduced in this paper.One W-band ex-tended interaction klystron（EIK）is used as the final stage amplifier of the transmitter.The working princi-ple,characteristics,and applications request of EIK are introduced.The design ways of the focusing elec-trode pulse modulator and high voltage power supply（HVPS）are described.The HVPS is a capacitance clamp phase-shifted convertor.The function of control circuit is given.Finally,the test result of the W-band transmitter is showed.
