This article presents the design, conceptualization, and validation of a generalized architecture for a Wilkinson Power Divider (WPD). The proposed design strategy highlights the versatility of incorporating a broad variety of dual‐band impedance transformers as a part of the WPD, thereby extending its range of applications. As an example, a DC blocking variant of the proposed WPD has also been designed for demonstration. Simple closed‐form design equations have been developed and validated with classical examples and case studies. Finally, two prototypes‐ one ordinary and another DC blocking variant have been fabricated on RO4350 (ɛr = 3.6) substrate and measured. The measurement results are well in accordance with the simulations, thereby validating the proposed design theory.

“…Subsequently, there has been an increased interest in the design and development of multiband PDs owing to the rapid advancements in the multiband/multi-standard communication systems [4]- [6]. However, emergence in advanced wireless technology has also seen a recent surge in impedance transforming PDs [7]- [10]. This has been necessitated by the fact that often there exists a wide impedance variations between the ports of PDs and interconnecting circuit blocks.…”

“…These impedance transforming power dividers (ITPDs) enable the overall circuit miniaturization, too, by eliminating the additional impedance transformers at the ports in a communication system. A number of power divider schemes with distinct features and functionalities exist in the literature [7]- [10], [18]- [22]. In brief, there are either single-band ITPDs with real or complex impedances [7]- [10], [18], [19] or dualband ITPDs with only real impedances [20]- [22] at the ports.…”

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.

“…Wilkinson power dividers (WPDs) in integrated circuit forms have been widely studied in the microwave and millimeter-wave frequency ranges. Lumped transmission line circuits have been used to replace distributed transmission lines in designing single-frequency, dual-band, wideband and ultra-wideband power dividers [1][2][3][4][5][6][7][8][9][10][11][12]. Lumped transmission line circuits are generally in the form of right-handed (or conventional) transmission lines, but lefthanded and composite right-/left-handed transmission lines have also been found in many applications [13].…”

This paper presents a Wilkinson power divider using a common inductor. The lumped topology uses the inherently inductive loss of the inductor as a part of the design, so the conventional resistor for high isolation can be omitted. Therefore, low-loss and high-isolation performances of the compact circuit were achieved. The proposed 2.5-GHz divider was implemented on a silicon-based integrated passive device process. Measurement of the prototype chip had a reflection coefficient below 18 dB at all ports, an insertion loss of 0.5 dB and isolation above 28 dB. The chip size is merely 0.011o  0.019o. INDEX TERMSWilkinson power divider, lumped transmission line, resistorless, common inductor, integrated passive devices.
