Bitron, as a new type of high-power microwave device, is studied in this paper. The parameters (such as microwave power and its efficiency) based on the theoretical analysis has been realized on 25D Particle in Cell (PIC) simulation code. This device is composed of two parts: a modulation cavity and an output cavity . Coupling exists between these two cavities, so the oscillation occurs under ce rtain conditions. X band bitron is designed in this paper, and its theoretical e fficiency is 294%. The process is also realized by 25 PIC simulation code, w ith an efficiency 28%, microwave frequency 942GHz, and the power output 2 25GW.
