“…The output return loss S 22 shows a better response with −45 dB at both f 1 and f 4 , and better than −60 dB at the frequencies f 2 and f 3 . The insertion loss S 21 has the following values: −5 dB at f 1 , −5.21 dB at f 2 , −5.42 dB at f 3 , and −5.65 dB at f 4 . These values are close to the ideal value of −4.77 dB.…”

“…Moreover, a single resistor was only used, which did not provide good isolation between the output ports. Other structures were proposed [4][5][6], which employed extra transmission line sections and/or reactive components that make the design and its realization even more complicated. In [7], Oraizi presented the design of broadband asymmetric multi-section WPDs.…”

Abstract-In this paper, a new simple design procedure of multifrequency unequal split Wilkinson power dividers (WPDs) is presented. The procedure is based on using N -sections of transmission line transformers, instead of the conventional quarter-wave WPD branches, to realize a WPD that operates at N frequencies. Good isolation is achieved by using lumped resistors without any extra modification to the conventional structure of WPDs. The analysis, design procedure, and mathematical expressions are presented for arbitrary design frequencies, and arbitrary power split ratio. For verification purposes, a 1 : 2 dual-frequency, a 1 : 2 tri-frequency, and a 1 : 2 quad-frequency WPDs are designed and fabricated. The measured results show good agreement with those obtained using the presented design methodology and with full-wave simulated results.

“…In usual, the conventional power dividers are designed at a single band [8][9][10][11]. Recently, many researches have been made in designing new Wilkinson power dividers for dual-frequency application [12][13][14][15][16][17][18][19][20]. In obtaining ideal isolation effect in various dualfrequency power dividers, three novel isolation structures including parallel RLC [13], series RLC [14], and combining of parallel R and series LC [15] demonstrate better isolating effect than traditional single resistor isolators on the same layouts.…”

“…In [16][17][18][19][20], other modified types of Wilkinson power dividers without reactive components have been proposed to operate at dual band. In order to break the limit of equal output power at the two outports of these dual band power dividers in [12][13][14][15][16][17][18][19][20], dual band power dividers with unequal power dividing have been proposed in [21] and [22], however, the design parameters cannot be obtained using analytical approach [21] while the perfect matching of outports in the corresponding design procedure are not theoretically considered [22]. Furthermore, to obtain the perfect matching at all of ports and isolation between the two outports, a new unequal Wilkinson power divider for a frequency and its first harmonic has been proposed in [23].…”

Abstract-In this paper, we propose a generalized Wilkinson power divider operating at two arbitrary frequencies with unequal power dividing ratio. To achieve unequal power division and perfect matching at dual-frequency, a novel structure consisted of four dual-frequency transformers in two sections is proposed. For the compact power divider, the parallel and series RLC structures can be chosen to obtain effective isolation between the two outports according to different frequency ratios. Furthermore, the closed-form design equations of the unequal dual-frequency power divider are derived based on circuit theory and transmission line theory. Finally, simulation and experiment results of two examples including parallel and series RLC structures indicate that all the theoretical features of these unequal power dividers can be fulfilled at dual-frequency simultaneously.

A new dual-band Wilkinson divider structure is proposed for the arbitrary power division ratio and matched output ports. The compact dual-band stubbed P sections are employed in both the Wilkinson divider and the output matching section. It has simple structure based on the compact open stub topology and the overall divider length can be reduced in half as compared with similar works based on the two cascaded section transformers.
