Analytical Design Method of Multiway Dual-Band Planar Power Dividers With Arbitrary Power Division

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

“…We assume that the power-dividing ratio of the port 2 to the port 3 is expressed as P 2 /P 3 = k 2 . In addition, the equivalent impedances R 2 , R 3 in Figure 2 are defined as two real impedances, and their resistance values satisfy the following equation [10,13] …”

“…Therefore, when the microwave signals input from the port 1 in Figure 1, they can be divided into two separated unequal-magnitude signals without any losses. To obtain accurate unequal power-dividing performance, the input equivalent impedances Z in2 and Z in3 can be given by [10,13] …”

“…The additional transmission losses are inserted and the occupy size is still large in these modified dividers. Recently, dual-band Wilkinson power dividers are also be investigated by authors [11][12][13]. It is necessary to point out that one of these dividers uses couple line structures [12].…”

Design of a Compact Tri-Band Power Divider With Unequal Outputs

“…As to unequal power divider, dualband dividers are widely discussed [13,14] while tri-band dividers are seldom researched. In [13], a dual-band Gysel power divider with unequal outputs is presented.…”

“…In [14], a dual-band unequal Wilkinson power divider with arbitrary power division and arbitrary terminal impedances through recombinant structures and dual-frequency transformers is presented. But, the difficulty with the high distribution ratio multiband Wilkinson divider is the realization of high characteristic impedance transmission lines.…”
