摘　　要：本文从腔体尺寸角度出发,认为某一方向的尺寸随温度是线形变化的。推导出了腔体各个部件的温漂影响因子,该因子反映了腔体的某个部件对整个腔体的温漂影响的大小。用三维仿真软件HFSS和CST去计算部件温漂影响因子,所得结果基本一致。建立了抵消温漂的模型,由该模型出发合理设计腔体各部分材料,得出无温漂的腔体。用经过温补的腔体设计出了高温度稳定性的滤波器。This paper at the point of cavity size, view that the changes of the size at some direction is linear with temperature varies. Deduced the temperature drift factor of cavity’s components, the factor reflects the size of each component impact on the whole cavity’s temperature drift . By 3D simulation software HFSS and CST ,we can calculate the temperature drift impact factor of each component. The results agree with each other. Offset temperature drift model is established. The material of the cavity is rati...
