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.

“…However, multi-functional components may suffer from a large size and big design complexity. Tunable components, such as tunable filters [1][2][3][4], and function-merged components, such as filtering power dividers [5,6], are effective to moderate the problems mentioned above. Tunable filters can achieve tunable passbands [1,2], stopbands [3] or multi-functional performance [4], and filtering power dividers can be realized by embedding resonators into the power division arms [5,6].…”

Abstract-This paper presents an electronically tunable dual-band filtering power divider (TDFPD) with tuning diodes sharing technique. Two dual-mode tunable resonators (DMTRs) are embedded into a conventional power divider to achieve dual-band tunable bandpass filtering response. The two bands of the proposed TDFPD can be tuned independently. Tuning diodes sharing technique is utilized to reduce the number of tunable diodes. A prototype has been designed and fabricated to validate the proposed design as shown by the good agreement between the measured and simulated results. The measurement shows that the center frequencies of the lower and upper bands can be independently tuned from 1.31 to 1.62 GHz and 2.92 to 3.30 GHz, respectively. Within the passbands, isolation between the two output ports is higher than 16 dB with small phase and magnitude imbalance.

“…It is an effective way to achieve both multiple functions and small size by using electrically tunable technology as reported to realize tunable filters with central frequency tuning [1,2,3]. Integrating multiple components into a one is also a promising way for size reducing and multiple functions can also be obtained at the same time such as filtering power dividers [4,5,6,7,8,9], which consists of a filter and a power divider. In [4], filtering power dividers are realized by adding filtering structure to the input or output lines.…”

“…In [4], filtering power dividers are realized by adding filtering structure to the input or output lines. Moreover, in [5], bandpass filters are used to replace the transmission lines between the input port and isolation resistor to realize filtering power dividers. Multimode resonators are also used to achieve multimode and multiband filtering power dividers as reported in [6].…”

This paper presents a tunable dual-mode filtering power divider (TDFPD) with harmonic suppression. Two tunable dual-mode resonators are embedded into a power divider with equal power ratio to realize the proposed TDFPD. The odd-mode of the dual-mode resonator is rigorously designed to approach its even-mode so that the proposed TDFPD will show a harmonic suppression performance. Tuning elements sharing technology is also utilized to minimize the numbers of varactors. To demonstrate the proposed design, a prototype is designed and fabricated. The measurement shows the TDFPD can be tuned from 2.10 to 2.31 GHz with a return loss better than 15 dB and Harmonic suppression is better than 20 dB at the frequency range of 2.5 to 9 GHz. Good agreements are observed between measured and simulated results.
