In the last decade, the filter community has innovated both design techniques and the
technology used for practical implementation. In design, the philosophy has become “if you …

A general and direct synthesis technique of pseudoelliptic inline filters with arbitrarily placed
attenuation poles (APs)(transmission zeros) at real frequencies is presented. The APs are …

This article presents a novel class of dual-mode substrate-integrated waveguide (SIW)
bandpass filters exploiting perturbed SIW rectangular cavities. By introducing metallized via …

This article reviews the three key concepts of modern microwave-filter synthesis using
coupled resonators: coupling matrix (CM), extracted pole (EP), and nonresonating node …

In this article, we introduce a synthesis-based design approach for waveguide filters,
including singlets. As is known, a singlet block comprises one resonator coupled to source …

This paper presents a center frequency and bandwidth reconfiguration mechanism for
waveguide microwave bandpass filters. The filters are designed to be used in the output …

This paper proposes a novel and unified synthesis approach and design procedure for
microwave filters with extracted pole and nonresonating node (NRN) technique. By …

Frequency-dependent coupling (FDC) emerges as a new method to introduce the finite-
position transmission zeros (TZs) in the synthesis and design of filtering networks. In this …

A new structure based on an ellipsoidal cavity that operates with the fundamental mode and
its degenerate in a transverse routing scheme is presented in this letter. This configuration …

This article proposed an analytical synthesis approach of generalized strongly coupled
resonator triplet (GSCRT) filters, which eliminates the need for negative couplings …
