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

Abstract

Abstract-A generalized two-way coupled-line power divider with extended ports for dual band is proposed in this paper. The power divider is composed of two section coupled-lines, one conventional transmission line, and an isolation resistor, and employs extension of a transmission line or coupled-line at each port. The design equations are obtained based on even-and odd-mode analysis, and analytical ideal closed-form scattering parameter expressions derived. Because the traditional ring structure is a special case of coupled line, four cases of this generalized power divider are discussed and compared. In addition, the six power dividers simulated results of three special cases are shown. Finally, three fabricated power dividers measurements are used to certify this proposed structure and corresponding design parameters.

A New Dual Band Balanced-to-Balanced Power Divider

“…The influence of characteristic impedance Z x on bandwidths of the dual band is further studied numerically by using the method proposed in [15]. From Figure 5, we can find that the proposed power divider has its maximum bandwidth of 23.8 MHz with Z x = 48 Ω.…”

“…Closed-form design method of N -way dual-band Wilkinson power dividers has been discussed in [9]. One section or two section coupled line with one or two absorption resistors was studied in [10][11][12][13][14][15]. Periodically loaded slow wave structure was used for dual-band applications [16].…”

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].…”

A Dual-Band Impedance Transforming Technique With Lumped Elements for Frequency-Dependent Complex Loads

“…These dual-band transformers are realized for a real impedance load at two designated frequencies. Hence, they are applicable in passive circuits such as dual-band filters, dual-band power dividers and so forth [6][7][8][9]. In terms of active circuits, complex impedance transformers are required such as a dual-band amplifier [10][11][12].…”
