An approach to design quasi-elliptic-type planar filters with single-and dual-band bandpass
transfer functions and input-absorptive capabilities is presented. Two-branch channelized …

A balanced microstrip bandpass filter (BPF) with quasi-reflectionless (QR) characteristics on
both input and output ports and good common-mode (CM) rejection is proposed in this brief …

High-order single-ended and balanced wideband bandpass filters (BPFs) with quasi-elliptic-
type (QET) responses are reported. Firstly, a fifth-order wideband BPF based on a two-layer …

This article presents a concise two-port asymmetric reciprocal filtering network, which mainly
consists of short-and open-ended coupled lines for designing reflectionless bandpass filters …

In this paper, a reflectionless ultra-wideband (UWB) bandpass filter (BPF) is proposed based
on complementary diplexer, which is composed of a BPF and two bandstop filters (BSFs) …

In this article, novel packaged wideband highly selective filtering power dividers (FPDs) with
arbitrary phase shifts and power dividing ratios using multilayer stacked stripline are …

A two-layer wideband bandpass filter (BPF) with ultrabroad input-reflectionless stopband
range is reported. It consists of a two-port-reflectionless high-order quasi-elliptic-type (QET) …

A class of RF low-pass filters (LPFs) simultaneously featuring flat-in-band-group-delay and
input-quasi-reflectionless characteristics is reported for the first time. By means of a …

In this brief, the unequal-width three-coupled line section is adopted for the design of
miniaturized high-selectivity ultra-wideband reflective and absorptive bandpass filters …

A class of reflectionless RF bandpass filters (BPFs) with wideband quasi-constant in-band
group-delay response in transmission for high-data-rate digital-communication systems is …
