This paper describes analysis of the S parameter of an X-band (8-12GHz) Wilkinson power divider by using odd-even mode, as well as full circuit analysis technique. The closed-form model of the S parameters versus normalized frequency response of the power divider is proposed for the first time according to our acknowledgement. The expressions are compared with the results obtained from a full-wave electromagnetic simulator (ADS) and found to yield acceptable agreement: the insertion loss is -3dB, the maximum difference of return loss of port 1 and isolation is about 0.17dB, the return loss of port 2 is less than -38dB.

This paper presents design and simulation of wideband power amplifier based on multi-section Wilkinson power divider. Class-A topology and ATF-511P8 transistor have been used. Advanced Design System (ADS) software used to simulate the designed power amplifier. The simulation results show an input return loss (S11)-10dB, gain (S21)10 dB over the entire bandwidth, and an output power around 28dBm at the Centre frequency of 3GHz. The designed amplifier is stable over the entire bandwidth (K1). Inter-modulation distortion is -65.187dBc which is less than -50dBc. The designed amplifier can be used for the microwave applications which include weather radar, satellite communication, wireless networking, mobile, and TV.

In this paper, a compact 8 way microstrip line Wilkinson Power Divider (WPD) is designed and proposed. The equal power divider con-sists of multiple multi-section WPD’s with isolation resistors. By utilizing the multi-sections concept, a remarkably increase in the band-width is observed. In the design process, RT 5880 substrate is used with the thickness of 0.8 mm and dielectric constant of 2.2 and loss tangent of 0.0004. The simulated results such as return loss, insertion loss and isolation are plotted by using ADS simulation software and obtained results show good agreement.

In this paper, a novel analytical design technique is presented to implement a coupled-line wideband Wilkinson power divider (WPD). The configuration of the WPD is comprised of three distinct coupled-line and three isolation resistors. A comprehensive theoretical analysis is conducted to arrive at a set of completely new and rigorous design equations utilizing the dual-band behavior of commensurate transmission lines. Further, the corresponding S-parameters equations are also derived, which determine the wideband capability of the proposed WPD. To validate the proposed design concept, a prototype working at the resonance frequencies of 0.9 GHz and 1.8 GHz is designed and fabricated using 60 mils thick Rogers’ RO4003C substrate. The measured result of the fabricated prototype exhibits an excellent input return loss > 16.4 dB, output return loss > 15 dB, insertion loss < 3.30 dB and a remarkable isolation > 22 dB within the band and with a 15 dB and 10 dB references provide a fractional bandwidth of 110% and 141%, respectively.

This work presents a miniaturized X-Ku band Wilkinson power divider (WPD), based on 0.18μm 1P6M CMOS foundry technology. The proposed two-dimensional transmission line, called a complementary-conducting-strip (CCS), replaces the conventional microstrip (MS) line structure. With this CCS structure, the occupying area of this novel divider is about 96 % smaller than that of the conventional MS WPD. The prototype occupies an area of only 345 μm by 360 μm without input/output (I/O) pads. The new WPD has an insertion loss of 4.9 dB, an isolation of 13 dB and a return loss 12 dB between 8 GHz and 18 GHz.

In this paper, for the first time, we present a novel Pi-shaped structure using resonators for multiband applications. The multiband Pi-shaped structure with LC resonators is analyzed. In order to demonstrate the proposed multiband Pi-shaped structure, one tri-band Wilkinson power divider and one tri-band rat-race coupler are designed, fabricated, and tested. The compactness of the two demonstrated components is well kept by putting all stubs with resonators inside the components themselves. Measured results are in good agreement with the simulated results.

AbstractIn this study, a three-way Wilkinson power divider (WPD) was proposed the circuit whose center frequency was selected as 1.9 GHz operates between 0.95-2.95 GHz frequencies and has a bandwidth of approximately 105%. The simulation and measurement results of the designed circuit were well aligned with each other below 10 dB return loss and 13 dB isolation. In addition, 0.4, 0.3 and 1.0 dB insertion loss were obtained in the output ways, respectively. The circuit is made more compact thanks to the curved structure of the output ways. It has been found that the proposed three-way power divider takes about 35% less space than the conventional circuit design.
