摘要
为了给需要大功率扫频微波源的变频微波加热、通信干扰等领域提供一种高效低成本的解决途径,在磁控管注入锁频理论的基础上,提出了一种基于磁控管的扫频大功率微波源。首先通过磁控管的等效电路模型对该设想进行了可行性分析,然后在微波仿真软件CST STUDIO SUITE中对磁控管建模并进行particle-in-cell仿真验证。分析了注入比对磁控管高频电压输出以及频谱的影响。磁控管的最高扫频带宽可达21 MHz。
A high-power sweep frequency microwave source of magnetron based on injection-locking theory is proposed to meet the requirements of variable frequency microwave heating, communication jamming and other fields. The theoretical analysis of the equivalent circuit model of magnetron is conducted in the first place. Then, the model of Continuous-Wave（CW） magnetron is established in CST STUDIO SUITE to work on the simulation verification of particle-in-cell. The effects of injection ratio on magnetron RF voltage and spectrum are analyzed at last. And the maximum sweep bandwidth of magnetron output turns out to be 21 MHz.
