In this article, a novel topology of wideband on-chip Wilkinson power divider (WPD) with good insertion loss (IL) performance is proposed and demonstrated on gallium arsenide (GaAs)-based integrated passive device (IPD) technology. The proposed WPD is further analyzed by the even and odd method.To verify the advantage of the proposed WPD against the conventional one, two examples are numerically investigated, showing that the proposed one achieves better performance in terms of IL and isolation. In addition, the proposed design achieves a miniature area and small amplitude and phase imbalance (AI) performance. The fractional bandwidth (FBW) of the proposed WPD is 100% (6-18 GHz), where the magnitude imbalance is less than 0.08 dB and phase imbalance is better than 0.4 . Furthermore, the minimum IL is better than 0.96 dB and return loss is better than 13.7 dB within the core passband. Meanwhile, the isolation of the WPD is better than 17.6 dB. Finally, to further demonstrate our design conception, the proposed WPD has been fabricated on GaAs IPD technology with size of 1.5 Â 0.9 mm 2 , and measured by on-wafer probing. All the simulated and measured results of the proposed WPD are matched reasonably well with each other, thus firmly validating the claimed superior performance of the proposed WPD in the wide operating bandwidth, low IL, and high isolation.

“…Recently, the wideband WPDs have gained paramount importance in various applications such as power amplifiers [28][29][30][31], Hilbert transformer-based dual-band single sideband modulator [32,33], antenna arrays [34], phase shifters [35], and other RF front-end systems [36]. This is mainly due to the recent progress in high data-rate 5G/6G wireless systems that has refueled significant research interest in developing the next generation of wideband power dividers [37][38][39][40][41][42][43][44][45][46][47][48].…”

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.

A miniaturized wideband four‐way filtering power divider (FPD) is presented in this article. It is composed of unequal‐width three‐coupled‐lines (TCLs), stepped‐impedance open‐circuited stubs, and isolation resistors. By using two groups of the unequal‐width TCLs and the stepped‐impedance open‐circuited stubs, size reduced four‐way FPD with wideband filtering responses and out‐of‐band rejection is realized. Besides, good output ports matching and isolation are obtained by inserting two types of air‐bridge resistors. In the theoretical analysis section, the impedance matrix of the unequal‐width TCL is introduced, for the first time, and rigorous closed‐form design equations for the proposed FPD are also derived. Moreover, the methodology for computer‐aided design is given based on the design equations. For demonstration, a prototype operating at 1.5 GHz is designed, fabricated, and measured. The measured results validate the 80% bandwidth with more than 17 dB out‐of‐band rejection, more than 14 dB isolation and more than 15 dB return loss at all output ports. Compare with the reported four‐way FPD with similar bandwidth, a size reduction of 74% is obtained.
