摘要
介绍了一种简便实用的矩形波导双工器的工程设计方法。针对在宽频带跨度矩形波导双工器设计过程中,容易出现的低频通道高次模落入高频通道的问题,提出了预加载的解决方法。针对双工器在设计过程中频带跨度大的问题,设计了新型宽频带T形头结构。详细介绍了波导双工器的总体优化方法和步骤。文章的双工器设计实例中心频率分别为21GHz和29.5GHz,带宽均为300MHz,通带内隔离分别小于-120d B和-65d B。
A brief and practical method of H-plane waveguide diplexer design is introduced. For the issue of the harmonic of the low frequency filter in the high frequency filter, the method of preload is mentioned. A new structure three-port junction is designed for the diplexer with the band between the passband of two filters is wide. The integer optimize method of diplexer is introduced. The diplexer, in this literature, with the center frequency 21GHz and 29.5GHz and bandwidth 300MHz. The restrain excel -120dB and -65dB respectively.
