本摘记以有载Q值为出发点,比较和分析了两种常用的简单甘氏波导振荡器。提出了两种振荡器的适当的设计准则;经测试过的两种振荡器是非常符合这些设计标准的。结论是:既然,常用的机械上复杂得多的振荡器具有更好的适应性,但在大多数的应用场合,较简单的振荡器是足够的了。 Based on the Q value of load, this paper compares and analyzes two commonly used simple Gannan waveguide oscillators. The appropriate design guidelines for both oscillators are presented; the two oscillators tested are very much in line with these design criteria. The conclusion is: Since the commonly used mechanically more complex oscillators have better adaptability, simpler oscillators are sufficient in most applications.
