High-Isolation Resistorless Tunable Filtering Power Divider

2020 IEEE Radio and Wireless Symposium (RWS), 2020
This 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.

Filter integrated Wilkinson power dividers

Microwave and Optical Technology Letters, 2010
AbstractThis article presents design considerations of a filter integrated Wilkinson power divider (FIPD), which helps to reduce the circuit size.Theλ/4 impedance transformers of the conventional Wilkinson power divider are replaced by filters with an insertion phase of 90° at the center frequency. The concept is validated by two prototypes centered at

Filter-Based Wilkinson Power Divider

IEEE Microwave and Wireless Components Letters, 2014
A 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.

A reconfigurable filtering power divider

2016 IEEE MTT-S International Microwave Symposium (IMS), 2016
In 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.

Miniaturized Lumped-Element Power Dividers with a Filtering Function

IEICE Transactions on Electronics, 2008
Three miniaturized lumped-element power dividers with a filtering function for use in quadrature mixers are described. Simulation results showed that they can be miniaturized, as compared to conventional ones with open/short stubs, while maintaining the filter characteristics.

Filtering Power Divider With Phase Shift Output

2020 IEEE MTT-S International Conference on Numerical Electromagnetic and Multiphysics Modeling and Optimization (NEMO), 2020
This paper presents a power divider which realizes the average energy distribution of input signals, a fixed phase difference of output signals and filtering. The signal interference technology is used to realize the filtering function. The input and output of the filter have a phase difference of 90°, with 70.7 ȍ port impedance, which replaces the ...

Compact filtering power divider with harmonic suppression

Journal of Electromagnetic Waves and Applications, 2016
This 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

Balanced-to-single-ended filtering power dividers

2016 IEEE International Conference on Ubiquitous Wireless Broadband (ICUWB), 2016
Balanced-to-single-ended filtering power dividers have been used widely in modern communication systems due to their ability of easy connection with balanced and single-ended components simultaneously as well as differential-mode power division, common-mode suppression and filtering function, which is similar to balanced-to-balanced filtering power ...
