A power divider is ideally a lossless reciprocal device performing vector summation of two or more input signals, which is an extremely important circuit component in wireless communication systems or radar systems. In this paper, a general concept of lumped-element power divider is discussed. Then, a semi-analytical synthesis technique is presented. General odd-mode and even-mode analysis method is proposed for multi-port symmetrical network and applied in the analysis of N-way lumped-element power dividers. The transmission networks and the matching networks can be synthesized step by step, which greatly simplify their analysis. The transmission networks can be synthesized by those well-known synthesis techniques for two-port networks, and thus the transmission property of power dividers can be accurately controlled. The matching networks are determined by optimization to ensure certain isolation between the output ports. The design procedure is simple and accurate. Apart from the capability of power division, power dividers are also able to play the role of impedance transform and signal processing. Some examples of power dividers with filtering capability are presented for demonstration. In this paper, a general concept of lumped-element power divider is discussed.

“…As a Gysel power divider has advantages of high power capacity and easy layout, a lot of related research works have been reported: single or dual band operation [2][3][4][5][6] improving operating bandwidth [7][8][9][10] and out-of-phase feature [11][12][13]. To reduce the size of microwave sub-systems, Wilkinson or Gysel power dividers with filtering response have been introduced in [14][15][16][17][18]. For a single or dual band Gysel power divider, there are two methods to realize the required power dividing ratio between output loads.…”

Abstract-A modified Gysel power divider with arbitrary power dividing ratio is proposed in this letter. The power dividing ratio of the proposed circuit is determined by both the electrical lengths and characteristic impedances of transmission lines. The proposed circuit is analyzed based on transmission line theory, and design equations are derived. For verification, two prototypes operating at 2 GHz with power dividing ratios of 1 : 1 and 4 : 1 are designed, fabricated and measured, respectively. The measured results are in good agreements with the simulated ones.

“…Power dividers, fundamental RF and microwave passive component, are widely applied in RF/microwave passive/active devices and subsystems. For meeting such various demands of these systems, the technique of co‐designing multiple functionalities, such as multiband/wideband operation, filtering property, harmonic suppression, and phase shifting characteristic, to realize multi‐function power divider has promoted considerable research activities . For example, a compact dual‐mode dual‐band filtering power divider and two wideband four‐way out‐of‐phase power dividers were presented.…”

“…In order to solve the problem of harmonics, power dividers with harmonic suppression have been extensively investigated. Several methods have been proposed to design harmonic suppressed power dividers . Open and stepped‐impedance stubs loaded low‐pass filters are used for generating the desired out‐of‐band transmission zeros.…”

“…Furthermore, by employing stub‐loaded ring resonator, composite right‐/left‐handed (CRLH) transmission line resonators and embedded dual‐mode resonators, the harmonic suppression property can be realized in power dividers. Additionally, other structures have been used for harmonic suppression, such as short‐ and open‐circuit stubs and frequency‐selecting coupling structure . However, in the all‐aforementioned structures, the design of the power divider with merits of ultra‐wideband harmonic suppression and high level of attenuation is still the most important challenge.…”

A novel wideband power divider with ultra‐wideband suppression of harmonics is proposed in this paper. The power divider is composed of double‐sided parallel spoof surface plasmon polaritons transmission line (DSP‐SSPP‐TL) with periodical grooved bow‐tie cells. The cut‐off frequency of DSP‐SSPP‐TL can be flexibly adjusted by changing the parameters of bow‐tie cells. To demonstrate that, dispersion relations of the bow‐tie cells with different parameters are simulated, and three DSP‐SSPP‐TL counterparts are experimented. Then, a power divider centered at 3.31 GHz (f0) is designed, fabricated, and measured. Experimental results indicate that the 10‐dB return loss bandwidth of the proposed power divider is about 146% from 0.9 to 5.73 GHz, and the upper stopband is extended up to 40 GHz (12.1 f0) with the suppression level above 32 dB. Moreover, ultra‐wideband isolation between two output ports of the proposed power divider could be achieved by employing two lumped resistors between two DSP‐SSPP‐TLs.
