摘　　要：Ka波段星载高功率波导隔离器在进行真空下功率耐受试验时发生故障,经过排查定位为所使用的粘接胶层过量释气,形成局部低气压环境而引起击穿放电失效。根据此隔离器的结构特点,进行了失效分析,确定隔离器的失效原因并进行故障复现,为后续工艺改进提供了指导,提高了星载高功率波导隔离器质量的可靠性。The Ka-band high-power waveguide isolator for satellites failed during the power tolerance test under vacuum.The results show that the adhesive layer used was over-gassing,forming a local low-pressure environment and causing breakdown discharge failure.According to the structural characteristics of the isolator,the failure analysis is carried out to determine the failure cause of the isolator and carry out the fault recurrence,which provides guidance for the subsequent process improvement and improves the quality reliability of the high-power waveguide isolator for satellites.
