研究了W波段高频输出窗的工作特性及三个关键结构尺寸对工作特性的影响规律。结果表明,驻波比小于1.2的频带为94.21~94.76 GHz;驻波比小于1.1的频带为94.34~94.64 GHz;工作频带内无谐振模式;窗片厚度对工作特性影响最大。热力学分析显示,温度最高点和应力最大点分别位于陶瓷窗片中心和边缘;最高温度和最大应力分别为117℃和144MPa。研制并测试了W波段高频输出窗。测试结果表明,驻波比小于1.2的频带为94.13~94.60 GHz,驻波比最小值为1.06,对应的频率为94.40GHz。
The working characteristics of the W-band high-frequency output window and the influence of the three key structural dimensions on the operating characteristics are studied. The results show that the frequency band with standing wave ratio less than 1.2 is 94.21 ~ 94.76 GHz; the frequency band with standing wave ratio less than 1.1 is 94.34 ~ 94.64 GHz; there is no resonant mode in working frequency band; Thermodynamic analysis shows that the highest temperature and the largest stress point are located at the center and edge of the ceramic window; the maximum temperature and the maximum stress are 117 ℃ and 144MPa respectively. Developed and tested the W band high frequency output window. The test results show that the band with standing wave ratio less than 1.2 is 94.13 ~ 94.60 GHz, the minimum standing wave ratio is 1.06, and the corresponding frequency is 94.40GHz.
