本文介绍了一种频率在400 GHz左右的波导型混合耦合复用器。所设计的复用器有三个频段，带宽为25 GHz，通道之间没有频隙。该复用器由两个相同的波导支线正交混合耦合器和两个相同的基于波导感应虹膜窗的带通滤波器组成。为了找出多路复用器的关键元件，利用信号流图进行了网络分析。该多路复用器是基于直接加工技术制造的，加工精度在几微米量级。用矢量网络分析仪测得的S参数与模拟结果吻合很好。
This paper describes a waveguide hybrid-coupled multiplexer for frequencies around 400 GHz. The designed multiplexer has three bands with 25-GHz bandwidth and no frequency gap between channels. The multiplexer is composed of two identical waveguide branch-line quadrature hybrid couplers and two identical bandpass filters based on waveguide inductive iris windows. In order to find the critical element of the multiplexer, network analysis was carried out using signal flow graphs. The multiplexer was fabricated based on direct machining technology with machining accuracy in the order of a few microns. S-parameters measured with a vector network analyzer show excellent agreement with simulations.
