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.

“…The even-odd mode analysis method is often applied in the symmetrical circuits of three-port device. 14,15 There are two identical networks which are divided according to a symmetric reference plane, which is equally authentic to an ideal wall and a short circuit. In the odd mode, the reference surface is equivalent to an ideal electrical wall and equivalent to a short circuit.…”

In this letter, a novel lumped Wilkinson power divider (WPD) introducing capacitors on the isolation R of ultra wideband with good isolation and insertion loss (IL) performance is proposed with the help of gallium arsenide (GaAs) technology. With the even and odd method, the proposed WPD is better illustrated. The fractional bandwidth (FBW) is 104% (3-9.5 GHz). Besides, the return loss is better than 13.7 dB, and the IL is better than 0.62 dB within the passband. The isolation is better than 19.5 dB from 3 to 9.5 GHz. Finally, to better illustrate the design conception, it has been fabricated on GaAs integrated passive device technology with size of 1.37 Â 0.971 mm 2 , that is, 0.1 Â 0.072 λ g 2 , measured by on-wafer probing. All the final results of the proposed WPD are reasonably matched well.

“…Although power dividers of [6] have tunable power dividing ratio, suppression of harmonics has not been paid. This disadvantage can be seen in power tri-frequency power divider of [7]. To enhance of harmonic suppression disadvantage, power dividers with H-shaped resonators [8], four isolation stages for ultra-wide operational band [9] and embedding three-line coupled structures [10], are presented.…”

This paper proposed a new topology of Wilkinson power divider based on the one harmonic suppressor structure. In previous works, low- and band-pass filters have been used instead of quarter-wavelength lines in conventional Wilkinson's power divider design. But in this research, a low-pass filter as a suppressor connected to the input terminal, then using two simple elliptical resonators divide the power. As a result, there is no need to two suppressor structures symmetrically. The operation of the power divider in this topology is that the spurious signals are completely suppressed by the suppressor structure, then the signal is divided and reaches the output terminals with the desired frequency. This innovation is being introduced for the first time. On the other hand, the proposed suppressor structure has two rectangular elliptical resonators with a long base length and two pairs of rectangular resonators with a short base length to suppress harmonics up to sixth order. Next, the power is divided using two circular elliptical resonators. The measurement results show that the insertion and return losses are 3.09/3.11 dB and 30 dB, respectively at 1 GHz frequency, and suppression of harmonics up to the 18th order.
