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.

“…As the result, designs in [40] and [41] have narrow bandwidths. Another impedance matching network mentioned in [42] can only realize transformation between two real-value impedances. The tri-band impedance transformer used in this paper can transform frequency-dependent complex impedances to a real-value impedance.…”

In this paper, a tri-band impedance transformer (TBIT) using a coupled line and a dual-band to tri-band transformer is proposed, which can transform frequency-dependent complex impedances to a real-value impedance. In order to explain how to determine circuit parameters, closed-form equations are derived in detail. Based on the TBIT, a compact T-junction power divider (TTPD) is designed. This TTPD works at three different frequencies with independent controllable power division ratios. Simple steps to design the TTPD are listed. To demonstrate the validity of the theory, this paper exhibits a prototype operating at 2, 4.4, and 5 GHz with different power division ratios. Moreover, the simulated and measured results prove that this TTPD has the features of tri-band operation, independent controllable power division ratios, enhanced bandwidths, and small size. INDEX TERMS Independent controllable power division ratios, tri-band, impedance transformer, power divider.

In this article, a novel design of quad‐band matching network (QBMN) with ultra‐high impedance transforming ratios (UHTRs) is proposed and designed based on ABCD matrix method. The QBMN is capable of matching a very large real load impedance at four different frequencies simultaneously. The quad‐band structure is composed of π‐section with series connected coupled lines at each port. The design formulas of QBMN are derived analytically to obtain the quad‐band operation. In order to validate the proposed idea, three examples of QBMN for different load impedances (500, 1000, and 1500 Ω) are considered. Finally, two QBMNs with transforming ratios of 10 and 20 are fabricated and demonstrated. For both the prototypes, the measured S11 is better than 15 dB at all working frequencies. The experimental performances are consistent with the simulated results.
