摘要

在这项工作中，我们研究了基于双腔和三腔微带结构的双工器开发的可能性，该结构实现在高相对介电常数εr=80的衬底上，并且没有短路元件，这决定了它们的高可制造性。确定了在相邻通道的频率区域形成微带结构的至少两个工作衰减极点的条件。结果表明，在每个通道滤波器中谐振器数量有限的情况下，串扰衰减达到至少55 dB的水平。

Microwave Diplexers Based on Two- and Three-Resonators Microstrip Structures

In this work, we investigated the possibility of diplexers` development based on two- and three-resonator microstrip structures implemented on a substrate with a high relative dielectric constant εr=80 and without short-circuited elements, which determines their high manufacturability. The conditions for the forming of at least two working attenuation poles of the microstrip structures in the frequency regions of adjacent channels are determined. It is shown that the crosstalk attenuation with such a limited number of resonators in each channel filters reaches a level of at least 55 dB.
