Microwave power module integrates the advantages of solid component and electro vacuum efficiently. Microwave power module has a very compact configuration. Then a very small and light modulator is needed to provide video pulse for the grid of the mini traveling wave tube. First of all, the advantages and disadvantages of several pulse transfer modes are analyzed. Considering the characteristics of microwave power module, transformer transfer mode is selected. Secondly, a novel circuit of floating plate modulator is introduced in this paper, which structure is very simple, and is suitable for miniaturization. Then, the operating principle of the circuit, especially the key parts, is analyzed in detail. In the end, this paper shows the experiment results which prove the feasibility of the circuit.
