Filter-Based Wilkinson Power Divider
IEEE Microwave and Wireless Components Letters, 2014A bandpass Wilkinson power divider with a wide stopband is proposed in this letter. A three-terminal and two-pole bandpass filter and two lowpass filters are employed to substitute two quarter-wavelength transformer in the conventional Wilkinson power divider. The proposed divider achieves not only bandpass response but also a very wide stopband.

High-Isolation Resistorless Tunable Filtering Power Divider
2020 IEEE Radio and Wireless Symposium (RWS), 2020This paper presents a novel architecture for a resistorless tunable filtering RF power divider with good isolation. The design is based on coupled dual-mode cavity resonators. At the even mode excitation, the primary resonance mode is coupled through the evanescent resonators, delivering the filtering response.

A reconfigurable filtering power divider
2016 IEEE MTT-S International Microwave Symposium (IMS), 2016In this paper, a filtering reconfigurable power divider is proposed based on novel switched-filter matching network (SFMN). The reconfigurable impedance matching can be obtained by applying different bias conditions to the p-i-n diodes loaded at the resonators and the feed lines.

Compact filtering power divider with harmonic suppression
Journal of Electromagnetic Waves and Applications, 2016This paper presents a novel power divider with flltering responses. By using quarter- wavelength resonators with a novel feeding structure, both power division and bandpass responses are obtained, and compact size is realized. Discriminating coupling is utilized to suppress the third harmonic to obtain wide stopband. The isolation resistor is connected
