摘　　要：大功率同轴腔体滤波器在无线通信系统中有重要的作用,同轴谐振器是其核心组成部分。研究了同轴谐振器表面粗糙度对品质因数的影响,通过仿真得出了同轴谐振器品质因数随表面粗糙度变化的曲线,划分了高Q稳定区、Q值快速下降区和低Q缓慢变化区,并研究了表面粗糙度对不同频率的谐振器品质因数的影响,最后对生产工艺环节给出控制建议。High power coaxial fi lters with coaxial resonators as the core component plays an important role in wireless communication systems.The influence of surface roughness on quality factor of coaxial resonators is investigated,the curve of the quality factor changing with surface roughness is obtained through simulation.The high-Q stable region,the rapid decline region and the slowly changing region of Q value is divided.In addition,the infl uence of surface roughness on quality factor of coaxial resonators with different frequency is researched.Finally,the suggestions for the production process are provided.
