An Unequal Coupled-Line Wilkinson Power Divider for Arbitrary Terminated Impedances

Abstract

Abstract-A unequal Wilkinson power divider based on asymmetrical coupled line section is presented in this paper. The proposed unequal Wilkinson power divider topology uses asymmetrical coupled-line section and two transmission-line transformers. For simplification, a section asymmetrical coupled line is applied to obtain front compact matching structure.For generalization, three ports terminated impedances are defined as arbitrary values. In particular, the output ports impedances are arbitrary complex values. Design parameters and analysis equations for scattering parameters are also provided. In addition, the theoretical external performances of several examples are illustrated. Finally, the EM simulated results are validated with the characterization of two microstrip unequal power dividers at 2 GHz.

An Improved Uwb Non-Coplanar Power Divider

“…As we know, the classical Wilkinson power divider [1] and its improved structures have been presented in the previous papers [2][3][4][5][6][7]. On the other hand, the other forms of power dividers with different design methodologies have been proposed [8][9][10][11][12].…”

Design of an Ultra-Wideband Power Divider via the Coarse-Grained Parallel Micro-Genetic Algorithm

“…The power divider is one of the key passive components in the design of microwave circuits and antenna arrays, but due to the limitation on frequency bandwidth, which is not suitable for the UWB systems [3][4][5]. So wideband power dividers are needed.…”

A Generalized Coupled-Line Dual-Band Wilkinson Power Divider With Extended Ports

“…Obviously, the coupled-line dual-band power divider has compact size. In addition, other coupled-line power dividers are studied in [28][29][30][31].…”

“…In [22,23], the novel methods are presented for the design of multiband power dividers. After decreasing the inherent circuit size of the conventional Wilkinson power divider and to develop high performance power dividers, coupled-line sections are used to design power divider [24][25][26][27][28][29][30][31]. The power divider given in [24] is single-band design, and provides more freedom of design parameters.…”
