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

Filtering Power Divider With Arbitrary Prescribed Phase Difference
2020 IEEE Asia-Pacific Microwave Conference (APMC), 2020This paper presents a design of filtering power divider with the arbitrary prescribed constant phase difference between two different paths. The proposed circuit consists of a Wilkinson power divider (WPD) and Nth-order coupled line bandpass filters (BPFs) with different fractional bandwidths (FBWs).

Design of microstrip power dividers with filtering functions
2012 42nd European Microwave Conference, 2012This paper presents the design of a novel microstrip power divider/combiner able to provide a selective bandpass filter. The structure consists of a combination of several T-junctions with novel configurations to generate frequency-variant couplings (FVC). These FVC also create n+1 transmission zeros in the frequency response.

Third-Order Filtering Power Divider with Sharp Selectivity
2020 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2020This paper presents a novel microstrip filtering power divider, whose transmission property is featured by a third-order general Chebyshev bandpass response. A transmission zero near the right side of the passband greatly improves frequency selectivity.

High performance balanced-to-unbalanced filtering power divider
2017 IEEE Electrical Design of Advanced Packaging and Systems Symposium (EDAPS), 2017A novel balanced-to-unbalanced filtering power divider using ring resonators is proposed. Due to the symmetry of the circuit model, even/odd-mode analysis method is applied to deduce the design equations at the operating frequency. The ring resonators can bring two transmission zeros in each side of the passband for differential-mode, which can improve

Frequency-Tunable Filtering Power Divider With New Topology
IEEE Transactions on Components, Packaging and Manufacturing Technology, 2017In this paper, we present a new frequency-tunable filtering power divider structure and its design method. For achieving the frequency filtering characteristic, the power divider uses a single resonator or multiple resonators. One of the unique features of the presented structure is that the last resonator is coupled to the two outputs, and this allows

Design of a Microstrip Diplexing Filtering Power Divider
2019 IEEE Asia-Pacific Microwave Conference (APMC), 2019A diplexing filtering divider is proposed by using arbitrary even-order Butterworth-type filtering transformers and two extra matching lines. The matching design is similar to that of the T-junction design of a conventional diplexer. Therefore, the required matching conditions can be easily achieved by designing two properly 50-Ω lines.

Wide-band Filtering Power Divider Using Coupled-Line
2021 IEEE 4th International Conference on Electronic Information and Communication Technology (ICEICT), 2021In this paper, a compact wideband filtering power divider (FPD) with nice performance is presented. The required power division function is realized by the introduced looped coupled-line structure. Moreover, three coupled-lines with different terminal conditions are used to introduce multiple transmission zeros (TZs) and transmission poles (TPs).
