“…The size of the fabricated prototype, integrated with the impedance transformers at the ports, are on the lower side. It is also found that the proposed ITPD has superior amplitude and phase imbalance performance over mostly published state-of-the-art designs such as [22], [36], [38], [39]. Clearly, the achievable r and k with the proposed ITPD is highest among the earlier published ITPDs.…”

In the design and development of front-end communication systems, the arbitrary impedance environments are encountered frequently. In this article, a three-port dual-band equal power divider is proposed which also transforms all types of impedance environments at its ports inherently. The power divider is suitable for a wide range of arbitrary frequency ratios and impedance terminations at each of the input and output ports. A systematic design procedure with a design flow graph is provided. The closed-form design equations make the design process simple and quick for prototyping purposes. The proposed design approach enhances the design flexibility significantly with the presence of multiple independent variables. Design examples with distinct design specifications are provided to demonstrate the effectiveness and flexibility of the architecture. A prototype working at 1/2.6 GHz and with frequency-dependent complex load (FDCL) terminations at the input and output ports is fabricated and measured to validate the proposed architecture and design methodology. The proposed dual-band impedance transforming power divider exhibits controllable bandwidths, planar structure without any reactive element, compact size, and the ability to provide port matching for any real, complex, and frequency-dependent complex impedance terminations.INDEX TERMS Frequency varying impedances, dual-band power divider, frequency-dependent impedance transformer, high frequency ratio, impedance matching, impedance transforming power divider, microstrip power dividers, transmission line.

In this paper, we present a topology with design equations for the rigorous design of multiway power dividers having a pre-defined filtering response featuring broadband isolation between any pair of output ports. Hence, a filtering power divider designed using the presented topology and design formulas can suppress undesired oscillations at the spurious frequencies when used as a combiner. More importantly, we provide complete mathematical design equations for designing filtering power dividers with various predefined filtering responses. Therefore, it is possible to design a filtering power divider without relying on time-consuming parametric sweeps or heuristic approaches. The presented filtering power divider topology and design equations have been verified by designing, fabricating, and measuring a four-way second-order filtering power divider.

This paper presents two narrow-band power dividers with a wide range power-dividing ratio based on the two new controlling insertion loss methods, which are low-impedance line and coupling capacitor. Initially, a narrow-band BPF is designed based on the equivalent circuit model and LC equivalent circuit. Then, using the surface current density, it is determined by which part of BPF structure the insertion loss (IL) can be controlled at center frequency. The tunable Wilkinson power dividers (TWPDs) are designed based on IL control components to create a wide range of power-dividing ratios, using only two DC voltages. The center frequency of first designed TWPD is 2.5 GHz, and the power-dividing ratio can be controlled up to 1:45 by variation of two DC voltages from 0 to 8 V. Since the structure of TWPDs are symmetric, the inverse voltages results in the inverted divided power between the output ports. The center frequency of second designed TWPD is 2.52 GHz, and power-dividing ratio can be controlled up to 1:134 by variation of two DC voltages from 1.7 to 4 V. Two proposed TWPDs are fabricated and measured. Comparisons of the measured and simulated results are presented to verify the theoretical predictions.
