摘要

本文提出了一种专门基于耦合谐振器的紧凑新颖的双工器和功率分配器耦合结构。它由两个交叉耦合结构组成,由两个共用谐振器连接在一起,其中只有四个谐振器。对于双工器来说,它代表了最紧凑的拓扑之一,可以产生两个具有两个完全可控传输零点的二阶信道滤波器。这可以用于在不增加谐振器数量的情况下增加通道之间的抑制和隔离。同样的拓扑结构也可以用于实现三阶滤波功率分配器(FPD),其嵌入式级联三段(CT)结构产生不对称传输零点。合成了几种双工器和功率分配器的耦合矩阵。为了验证器件的概念,已经证明了两个具有不同传输零点位置的微带双工器。具有5%的部分带宽的1.8GHz FPD也已被原型化,显示出在1.71GHz以下从15dB到25dB的带外抑制改善。通过只添加一个电阻器,研究了分压器的隔离性能,并将其从7dB提高到18dB。

A COMPACT COUPLING STRUCTURE FOR DIPLEXERS AND FILTERING POWER DIVIDERS
This paper presents a compact and novel coupling structure for diplexers and power dividers based exclusively on coupled resonators. It consists of two cross-coupled structures joined together by two common resonators with a cluster of only four resonators. For a diplexer, it represents one of the most compact topologies that produces two 2nd-order channel filters with two fully controllable transmission zeros. This can be used to increase the rejection and isolations between channels without increasing the number of resonators. The same topology can also be used to realise a 3rd-order filtering power divider (FPD), with its embedded cascade trisection (CT) structure generating an asymmetric transmission zero. The coupling matrices of several diplexers and power dividers have been synthesized. Two microstrip diplexers with different positions of the transmission zeros have been demonstrated to verify the device concept. A 1.8 GHz FPD with a fractional bandwidth of 5% has also been prototyped, showing an improved out-of-band rejection from 15 dB to 25 dB below 1.71 GHz. The isolation performance of the divider has been investigated and improved from 7 dB to 18 dB across the band by adding only one resistor.
