Ku波段同轴渡越时间振荡器的仿真研究
Simulation of Ku-band Coaxial Transit-time Oscillator
摘要
Abstract
A Ku-band transit-time oscillator based on four-cavity coaxial structure is designed,with the output frequency of 14.2GHz.The eigenmode algorithm combined with 2.5-D particle simulation method is adopted in simulation design.The initial values of each resonator are determined through cold cavity simulation,and then comprehensive optimization of hot cavity simulation is carried out.The efficient numerical calculation significantly reduces optimization time,effectively enhancing design efficiency while maximizing the beam-wave conversion ef-ficiency of devices.The typical simulation results show that when the diode voltage is 410kV,the current is 9.0kA and the guiding magnetic field is 0.8T,the power at the center frequency of 14.2GHz is 0.87GW,and the conver-sion efficiency is 23%.关键词
