“…It can be seen that the microstrip lines on the top and bottom layers are symmetrical, except the two output ports, indicating that the evenand odd-mode analytical method can be used in this paper [3][4][5][6][7]. There is a hole in the middle layer to ensure that the copper cylinder (CC 2 ) cannot be connected to the conductor.…”

“…According to the open literatures, the research about out-of-phase PD can be classified into single-band equal PD [1], single-band PD with arbitrary power division ratio [2], dual-band application [3][4][5], and single-band PD with complex impedance transformation [6,7].…”

“…The rat-race couplers based on the planar microstrip lines in [22,23] realize equal power division with filtering function; however, the out-of-phase performance is only limited near the operating frequency. The three-layer out-of-phase PDs [1][2][3][4][5][6][7] possess better out-of-phase performance than the rat-race couplers because the double-sided parallel-strip lines (DSPSLs) belong to the balanced transmission lines.…”

Abstract-In this paper, a three-layer circuit structure based on double-sided parallel-strip lines (DSPSLs) is proposed to design one out-of-phase power divider (PD) with equal power division and harmonic suppression. This PD, which is composed of four DSPSLs, one middle conductor, and two grounded resistors, features transmission suppression at two specified frequencies and all the even-order harmonics. Closed-form design equations are derived based on the traditional even-and odd-mode methods, and the circuit scattering parameters are also given. Finally, a practical PD operating at 0.92 GHz is designed and fabricated. The measured results show that this PD has equal power division with out of phase, harmonic suppression, good ports matching, and high outputs isolation.

“…However, these structures suffer from large circuit size, which make them unsuitable for compact system. To design compact out-of-phase PD without phase shifter, a lot of structures have been reported [11][12][13][14][15][16][17][18][19]. According to the layers of the reported works, out-of-phase power dividers can be classified into two types: multilayer structures [11][12][13][14][15][16][17] and uniplanar structures [18,19].…”

Abstract-A new out-of-phase power divider (PD) without phase shifter at the output ports is proposed. Based on admittance matrix, a new topology of uniplanar power divider with symmetrical outputs is designed. Under conditions of good matching, perfect isolation, and 180 • phase difference between two output ports, the corresponding design equations and synthesis procedures are derived and given with admittance matrix. To verify the design approach, an out-of-phase power divider operating at 2 GHz with equal power division ratio is designed, fabricated, and measured. Experimental results demonstrate that the input return loss is better than 32 dB, the insertion loss is less than 0.29 dB and the isolation is better than 33 dB. The amplitude imbalance between the output ports is 0.03 dB and the phase difference between the two output ports is 181.6 • at the operation frequency. Further more, 49.9% relative bandwidth of 15 dB return loss and 39.4% relative bandwidth of 20 dB port isolation are achieved.

This article summarizes recent advances in the art of power splitter designs. Diverse design concepts and techniques proposed in recent years are introduced, mainly focusing on the out‐of‐phase power splitters, in‐phase power splitters, filtering power splitters, and high‐power waveguide power splitters. Because of the popularity of balanced circuits, out‐of‐phase power splitters are heavily demanded. The double‐sided parallel‐strip lines (DSPSLs), with the frequency‐independent out‐of‐phase characteristics, are attractive transmission lines for wideband out‐of‐phase power splitter designs. The design methods based on DSPSL for various power splitting responses have been presented, including single‐ and dual‐band, wideband, arbitrary power division ratios. Then, the research on in‐phase power splitters are addressed, focusing on dual‐band operation, arbitrary power division ratios, multiway division, reconfigurable responses, and size miniaturization. The four typical methods for achieving dual‐band operation and five methods for realizing unequal power division ratios are presented. In addition, some techniques for multiway power splitters and reconfigurable power dividers are introduced. As for size reduction techniques, the LTCC and MMIC fabrication processes are introduced and example designs are included. Later, the concept of filtering power splitters is introduced. The power splitters and bandpass filters are combined together to form dual‐function devices with both power splitting and filtering functions. The responses of equal and unequal power division ratios as well as dual‐band operation are presented with the associated design techniques. Finally, coaxial waveguide power splitters are introduced, which are suitable for high‐power millimeter‐wave applications. Various oversized coaxial waveguide structures and probe array arrangement are presented for multioutput applications. Furthermore, some advances on radial waveguide spatial power splitters are addressed and the typical examples are included.
