采用高Q腔稳定固态振荡器的方法大家都已知道,特别是用反射式高Q腔直接偶合的情形,已有实验报告,。我们用这种方法在11GHz频带上仪雪崩振荡器(IMPATT)的稳定度约改善了10倍。然而这种直接偶合方法有两种模式存在,这就有可能在一定条件下发生模式跳变。实用的振荡器必须确实工作在特定模式。为了探讨适当的 As we all know, the method of using a high Q-cavity stable solid state oscillator has been reported experimentally, especially in the case of direct coupling with a reflective high-Q cavity. We use this method to improve the stability of the IMPATT in the 11GHz band by about 10 times. However, there are two modes for this direct coupling method, which makes it possible for the mode transition to occur under certain conditions. A practical oscillator must really work in a specific mode. In order to explore the appropriate
