In this article, we present a comprehensive discussion of a new class of inline microwave
filters with transmission zeros in the response, namely, the path filters. The main features of …

The generalized Chebyshev (pseudoelliptical) filter functions may not be optimal for certain
applications due to physical constrains. With redundancy in filter polynomials, this article …

In this article, a simple and general method for the design of cross-coupled bandpass filters
with compact size is proposed by virtue of the circular patch resonator. Owing to the unique …

In this article, a new class of high-order balanced dual-band high-temperature
superconducting (HTS) bandpass filter (BPF) based on modified multimode stub-loaded …

In this letter, an on-chip bandpass filter (BPF) with ultrawide-stopband and high selectivity is
designed and manufactured by 2-μm gallium arsenide (GaAs) HBT technology. For the sake …

This article proposes a compact dielectric waveguide filter (DWF) using dual external
coupling (DEC) and hybrid ridge and post resonators. The basic configuration comprises an …

This work deals with the design of true inline filters with two symmetric transmission zeros. A
new filters category named “path filters” is introduced (including the considered filters), its …

A new low-pass prototype, ie, cascade hybrid triplet (CHT), is proposed in this article. This
triplet, as a synthesis building block, offers two arbitrary-placed transmission zeros (TZs) to …

In this brief, a direct synthesis method is proposed to extract the coupling matrix of multi-port
filtering power divider (FPD) for mixed topology for the first time. Different from the existing …

We present an exact synthesis procedure for the low-pass prototype of extracted-zero filters.
This type of filter has been recently introduced and it allows the realization of a true inline …
