Abstract

This letter proposes a direct matrix synthesis approach for filters with cascaded extracted-pole (EP) sections. The novel synthesis technique is based on the observation that an EP section is a special case of a singlet with a zero mainline coupling. With proper phase lengths inserted into a cross-coupled network, cascaded EP sections can be directly synthesized from the canonical wheel form by a sequence of elementary matrix operations. In this letter, the equation for the suitable phaselength is derived, and the matrix transformation strategy to synthesize cascaded EP sections is developed. Numerical synthesis examples are provided to validate the novel synthesis approach.

级联提取极段滤波器的矩阵合成

本文提出了一种直接矩阵合成方法，用于级联提取极(EP)部分的滤波器。这种新的合成技术是基于观察到极电位段是具有零主线耦合的单重态的特殊情况。在交叉耦合网络中插入适当的相位长度，可以通过一系列初等矩阵运算直接从规范轮形合成级联极压截面。本文推导了合适相位长度的方程，并提出了合成级联EP截面的矩阵变换策略。数值综合算例验证了该方法的有效性。

期刊介绍： The IEEE Microwave and Wireless Components Letters (MWCL) publishes four-page papers (3 pages of text + up to 1 page of references) that focus on microwave theory, techniques and applications as they relate to components, devices, circuits, biological effects, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, medical and industrial activities. Microwave theory and techniques relates to electromagnetic waves in the frequency range of a few MHz and a THz; other spectral regions and wave types are included within the scope of the MWCL whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
