| 摘 要： | 文中讨论了一种1.25cm波段的波导型体效应振荡器。其主腔采用可调节的同轴减高波导座结构,使电路与二极管实现良好匹配。文中着重讨论了主腔各部尺寸对振荡器特性的影响。稳频腔采用高Q值的H_(011)模式圆柱腔,并采用线胀系数不同的金属材料进行温度补偿,提高了频率稳定度。利用WT55型体效应管,在23-25GH_2频带内,功率输出大于30mw,频率稳定度为5×10~(-5)。

| Abstract: | In this paper.a kind of waveguide Gunn effect oscillator at 1.25cm is discussed. Its main cavity uses the structure of adjustable coaxial height reduced waveguide. This makes the circuit match the diode well. The paper puts stress on discussing the influence of the size of each part on the characteristic of the oscillator. High Q H011 mode cylindrical cavity is used as the steady-frequence cavity and metal materials with different line-expand coefficients for temperature compensation is also used. These improve the frequience stead degree. In 23GH2-25GH2 band, using WT55 Gunn effect diode, the output power of the oscillator is larger than 30mw, the frequence stead degree is 5×10-5. |
