“…The comparisons of the proposed BTU filtering power divider with previous works are summarized in Table 2. It can be found that the proposed BTU filtering power divider has smaller size and wider upper stopband than the existing BTU filtering power divider designs [12]- [14], [18]- [25]. Furthermore, wideband CMS, large isolation, good DRL, and in-phase output characteristics are also obtained.…”

A miniaturized balanced-to-unbalanced in-phase filtering power divider with wide upper stopband and wideband common-mode suppression is proposed. The in-phase feature is realized by the coupled/non-coupled lines. The stub with shunt-capacitor is used to realize the functions of filtering and miniaturization. The closed-form design equations are provided and discussed. To verify the design equations, one prototype with a center frequency of 1.0 GHz is designed and fabricated. The measured differential return loss is greater than 15 dB in the range of 0.82-1.22 GHz (39.2%). The upper stopband rejection is better than 20 dB from 1.41 to 3.57 GHz. Common-mode suppression is greater than 20 dB from 0 to 3.7 GHz. The measured results are in good agreement with electromagnetic simulations.INDEX TERMS Balanced to unbalanced, filtering power divider, circuit miniaturization, in-phase, wide stopband.

“…Various techniques, such as rectangular-shaped resonators [7], circular-shaped resonators [8, 9], open stubs [10, 11], taper transmission lines [12], and coupled lines [13], have been used to design a PD by attenuating undesired signals and small dimensions. These structures are inefficient and complex, despite their excellent features.…”

In this paper, a new dual-band Wilkinson power divider (WPD) is designed and fabricated using novel low and high impedance stubs instead of quarter-wavelength transmission lines. The proposed circuit was analyzed using odd and even mode analysis, and the optimal values of design parameters were obtained using the particle swarm optimization algorithm. The designed power divider has input reflection coefficients (S11) of −22.1 and −17 dB at the first operating frequency of 2.2 GHz and the second operating frequency of 14.2 GHz, respectively. It also improves stop-band and fractional bandwidth (FBW) while maintaining a simple topology. The proposed WPD suppresses undesired harmonics from the second to the fifth with an attenuation level of less than −20 dB in the first band and generates a broad stop-band (4.4–11.5 GHz). In the first band, the FBW is 54.5%, and in the second band, it is 20.1%.

This paper introduces a simple H-shaped patch Wilkinson power divider (WPD), which provides ultra wide harmonics suppression band. The presented WPD designed at 1.8 GHz, and exhibits good performance at the operating bandwidth. In the proposed divider structure, two simple patch low-pass filters (LPFs) are employed at each branch, and three open ended stubs are added at each port. The proposed divider, implemented using the aforementioned structures has a good performance at both higher frequencies, and the operating frequency. In particular, the designed divider provides an ultra wide suppression band from 3 GHz to 20 GHz, which encompasses the 2 nd up to the 11 th harmonic. The proposed WPD has an operating band from 1.62 GHz to 2.1 GHz, with the operating bandwidth exceeding 480 MHz. Consequently, the fractional bandwidth (FBW) of 25.8 percent is obtained. The results indicate |S11|, |S12|, |S22|, and |S23|, are equal to -17 dB, -3.5 dB, -20 dB, and -17 dB, respectively, at the operating frequency. The simulation results are corroborated through the measurements of the fabricated divider prototype. The superior harmonic suppression capability is also demonstrated through comparisons with state-of-the-art divider circuits from the literature.
