已调信号注入磁控管的仿真研究
Simulation Study on Magnetrons with Modulated Signal Injection
摘要
Abstract
In order to overcome inherent shortcomings such as wide spectrum and large phase noise,injection locking technology is widely used in magnetronsto obtain more stable frequency and phase difference,and to effectively reduce phase noise.In previous injection locking theory,the external injection signal usually has single frequency which is close to the free-running frequency of the magnetron.In this research,an amplitude modulated signal is injected into magnetron to replace the single frequency signal.In this case,the magnetron acts as both oscillator and amplifier.The simulation results show that the frequency modulation can also be achieved when the carrier frequency of the amplitude modulation signal and the free-running frequency of the magnetron satisfy Adler condition.At this point,the magnetron output signal can be seen as an amplified modulated signal whose envelope is controlled by external injection amplitude modulation signal.In this process,information transmission is achieved with the frequency locking,which is expected to be applied to simultaneous wireless information and power transfer (SWIPT).关键词
