摘要
文章通过分析一种同轴谐振腔谐振频率随各部分结构尺寸变化的灵敏度和各部分结构尺寸随温度变化的灵敏度,得到了谐振腔谐振频率随温度变化的灵敏度,提出了采用变化量抵消来提高谐振腔温度稳定性的分析方法。利用这一方法,可以通过合理搭配谐振腔各部分的材料,利用不同的膨胀系数组合来实现温度补偿,进而实现采用常见易于机床经济加工的材料的合理组合来制造高温度稳定性谐振腔。
The thermal stability of resonator is mainly decided by the structure of resonator; the expansion temperature coefficient of the material of resonator, and the material electrical character variety with temperature. An absorption coaxial resonator was taken as an example in this paper to analyze the stability of resonator. By using the relative temperature sensitiveness of the resonator different part, methods to get a high thermal stability resonator by the means of using proper material of the different part of the resonator were proposed
