Abstract

This paper provides a compact, noncontiguous, high isolation, manifold triplexer operating from 25.8 to 49.5 GHz, a 62.95% wide fractional operating bandwidth. The triplexer is composed of three waveguide bandpass filters with Chebyshev responses. The initialization and loop optimization strategy of the triplexer are given. To eliminate undesired high-order mode transmission between common port and filters, ridged-waveguide topology, tuning screws, capacitive windows, and narrowing the wide edges of resonant cavities for the third filter are employed. The measured results and simulated ones are in good agreement. To our knowledge, this is the most broadband, high-power triplexer demonstrated to date.

具有高隔离度和高功率的毫米波超宽带三合一器

本文提供了一种结构紧凑、非连续、高隔离度的多路三工器，工作频率为 25.8 至 49.5 GHz，工作带宽为 62.95%。三工器由三个具有切比雪夫响应的波导带通滤波器组成。文中给出了三重器的初始化和环路优化策略。为了消除共用端口和滤波器之间不期望的高阶模式传输，采用了脊状波导拓扑结构、调谐螺钉、电容窗，并缩小了第三个滤波器谐振腔的宽边。测量结果与模拟结果非常吻合。据我们所知，这是迄今为止展示的最宽带、最大功率的三重器。

期刊介绍： Prediction through modelling forms the basis of engineering design. The computational power at the fingertips of the professional engineer is increasing enormously and techniques for computer simulation are changing rapidly. Engineers need models which relate to their design area and which are adaptable to new design concepts. They also need efficient and friendly ways of presenting, viewing and transmitting the data associated with their models. The International Journal of Numerical Modelling: Electronic Networks, Devices and Fields provides a communication vehicle for numerical modelling methods and data preparation methods associated with electrical and electronic circuits and fields. It concentrates on numerical modelling rather than abstract numerical mathematics. Contributions on numerical modelling will cover the entire subject of electrical and electronic engineering. They will range from electrical distribution networks to integrated circuits on VLSI design, and from static electric and magnetic fields through microwaves to optical design. They will also include the use of electrical networks as a modelling medium.
