A high power microwave detector based on thermionic diode

A novel high power microwave detector is investigated,which is based on the characteristics of thermionic diode. This kind of detector has a lot of advantages such as high power capability(up to 100 kW),fast response time(less than 2 ns),immune to the electromagnetic disturbance,etc.Additionally,it can work perfectly without synchronous signal. It can be made into the form of waveguide and coaxial detector.The waveguide detector is made up of a thermionic diode,standard waveguide,filter and external circuit,whose operating frequency is within the operating frequency range of the waveguide.And the coaxial detector is made up of a thermionic diode,coaxial line,filter and external circuit,which can work in a broad frequency range.The structure,the calibration method and results of the waveguide X-band detector are presented in this paper.The results show that the detector is suitable for peak power measurement of high power microwave,especially in the condition of high electromagnetic noise and high repetition pulses.
