With the development of wireless communication technology, radiofrequency (RF) circuits
and integrated circuits are becoming more complex and packing more functionality and …

This paper provides an overview of balanced (or differential-mode) structures operating at
microwaves, including common-mode suppression filters, balanced filters and circuits with …

A microwave device able to detect differential-mode to common-mode conversion (or vice
versa) in a four-port balanced circuit is proposed. For mode conversion detection, the …

Two novel balanced filters with wideband common mode suppression using dual-mode ring
resonators are proposed in this paper. Two and four transmission zeros close to the …

Two compact and high selectivity balanced bandpass filters with excellent common mode
rejection are designed in this brief. Compared with the half-wavelength microstrip …

In this paper, a novel terminated coupled line structure (TCLS) is introduced, which is
constructed by a coupled line section and four terminations loaded on it. Introducing different …

In this brief, for the first time, we propose common-mode (CM) and differential-mode (DM)
reflectionless balanced bandpass filters (BPFs) using half-wavelength ring resonator. By …

A high selectivity bandpass filter loaded with open stubs using dual-mode ring resonator is
presented in this letter. Sixth-order passband with six transmission zeros close to the …

A simple strategy is proposed to design differential-mode bandpass filters with good
common-mode (CM) rejection using simple resonators. Specifically, the CM rejection is …

The automated and unattended design of balanced microstrip wideband bandpass filters by
means of aggressive space mapping (ASM) optimization is reported in this paper. The …
