Analysis and Design of Balanced Dielectric Resonator Bandpass Filters
IEEE Transactions on Microwave Theory and Techniques, 2016This paper introduces an effective approach for differentially exciting the rectangular dielectric resonator (DR), which lays a foundation for designing balanced DR bandpass filters (BPFs). By analyzing the properties of the DR, it can be found that the $\mathrm {TE}_{11\delta }$ mode can be used for differential-mode (DM) operation while ...

Balanced bandpass filter with reflectionless common-mode suppression
2016 IEEE Electrical Design of Advanced Packaging and Systems (EDAPS), 2016A compact balanced bandpass filter using two types of LC resonator and quarter-wavelength resonator is proposed in this paper. By taking the advantage of the property of quarter-wavelength resonator and symmetry of the proposed circuit, a bandpass response can be achieved while the band stop response can be achieved at the same frequency band. Parallel

A narrow bandpass balanced filter with back-to-back structure
Proceedings of 2012 5th Global Symposium on Millimeter-Waves, 2012A narrow bandpass balanced filter with good common-mode suppression using back to back structure is designed in this paper. Under the differential- or common-mode excitation, the proposed configuration is separated as a bandpass filter or a bandstop characteristic, respectively.

Design of Three-pole Single-to-balanced Bandpass Filters
2006 European Microwave Conference, 2006A novel procedure for designing single-to-balanced filters is proposed. The proposed procedure can effectively convert a coupled resonator filter into a single-to-balanced filter without changing the frequency characteristics. Such conversion involves dealing with only a 2-port prototype.

A tunable single-to-balanced bandpass filter with bandwidth control
2018 Asia-Pacific Microwave Conference (APMC), 2018In this paper, a novel tunable single-to-balanced bandpass filter is proposed. It consists of three stepped-impedance resonators (SIRs), which are loaded and connected by varactors in between. With the very simple structure, the proposed reconfigurable filter can not only achieve center frequency control, but independent bandwidth tuning in the whole ...

A balanced wideband bandpass filter with one notched band
2016 IEEE International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2016A novel 5.8 GHz band-notched wideband balanced bandpass filter (BPF) is proposed in this paper, which obtains favorable uniform differential-mode (DM) response and good common-mode suppression. The proposed differential-mode BPF is comprised of a four-stage branch-line structure with one pair of open-circuited stubs in the symmetrical plane.

Compact Balanced Bandpass Filter With Wideband Common Mode Suppression
2020 IEEE Asia-Pacific Microwave Conference (APMC), 2020A compact balanced bandpass filter with wideband common mode suppression is proposed. Swap structures based on double-sided parallel-strip line (DSPSL) are used to realize 180° phase invert, which can provide an inherent common mode suppression in a wideband, and compared with half-wavelength transmission line in other work, this swap structure greatly

Balanced Dual-band SIW Bandpass Filter With Enhanced Selectivity
2020 IEEE MTT-S International Microwave Workshop Series on Advanced Materials and Processes for RF and THz Applications (IMWS-AMP), 2020The contribution of this work is to propose a novel substrate integrated waveguide (SIW) dual-band balanced bandpass filter (BPF) with enhanced selectivity. In order to achieve this aim, both source-to-load and cross-couplings are employed by implementing four resonant nodes in two cavities, for the purpose of generating one pair of additional ...

A Novel Balanced-to-Unbalanced Diplexer Based on Four-Port Balanced-to-Balanced Bandpass Filter
2008 38th European Microwave Conference, 2008In this work, a novel balanced-to-unbalanced (balun) diplexer is presented. By properly converting symmetric four-port balanced-to-balanced bandpass filter to a three-port device, a balun bandpass filter with high selectivity and extended stopband can be realized. Based on such a well-designed balun bandpass filter, a balun diplexer can be accomplished
