摘要 本文给出了用于补偿真空微波管增益波动的同轴谐振腔增益均衡器的一种新的设计方法。文中首先介绍了增益均衡器的作用与原理,然后给出了同轴谐振腔型增益均衡器的基本结构,并利用模式阻抗与驻波函数求得了谐振腔主传输线端的输入阻抗,最后利用等效电路求得了谐振腔的谐振频率。经与仿真软件的结果比对表明,利用本文方法所得到的结果是准确有效的。 A novel design of coaxial resonator microwave amplifier equalizer has been developed to effectively compensate the fluctuation of the gain of the microwave tube. The original work in the design is as follows: firstly, derive the output impedance of the equalizer to the main transmission line with the basic theory of electromagnetic fields, to be specific,by means of the modal impedance and the standing wave ftmction;next,figure out the gemetry of the equalizer and the relationship between the insertion point of the equalizer and the harmonic frequency;and finally, calculate the resonant frequency of the equivalent circuit with information available. The equalizer was numerically simulated. The results obtained with the equivalent circuit agree fairly well with the simulated ones.
