“…Comparing with the reported balanced power splitters, the proposed approach has all the functions of 1‐to‐ n way, filtering, single‐ended‐to‐balanced power splitting, and CM suppression. Comparing with the reported single‐ended‐to‐balanced power splitters, the prototyped 1‐to‐3 way design shows the performance advantages of low IL, wide bandwidth, 1‐to‐3 way and simple structure.…”

“…However, few SETBFPSs have been reported because more features, for example, filtering, should be considered. In Reference , the SETBFPS with arbitrary power ratio is achieved based on Wilkinson power splitter with independent impedance‐transformer and open‐circuited stubs. In Reference , a microstrip SETBFPS is achieved by coupled‐fed Wilkinson power splitter with multilayer 180° phase inverters.…”

An approach to 1‐to‐n (n = 3, 4…) way single‐ended‐to‐balanced filtering power splitter (SETBFPS) is proposed. The properly placed balanced ports with 0.5λg (λg is the substrate integrated waveguide [SIW] guided wavelength at f0) space make the TE32nd 103 and TE32nd 105 modes of n 32nd‐mode SIW multimode resonators form differential‐mode (DM) passband of the SETBFPS. Compared with the state‐of‐art single‐ended‐to‐balanced power splitters, the proposed approach has all the functions of 1‐to‐n way, filtering, and common‐mode (CM) suppression. A 1‐to‐3 way prototype is exemplified at 3.5 GHz with the minimum insertion loss (IL) of 0.09 dB, a fractional bandwidth (FBW) for a 15‐dB return loss of 35%, and a FBW for 15‐dB CM suppression of 52%. Low IL and wide bandwidth can be observed.

“…However, there are challenges from the common-mode noises and radiated electromagnetic (EM) interference for the multifrequency operation modes [1]. Compared to the traditional single-ended components, the balanced ones have the advantages of good common-mode suppression and high immunity to environmental and device electronic noise, such as balanced filter [2]- [4], balanced power divider [5]- [7], and balanced coupler [8]- [10]. Furthermore, the dual-band balanced components can be more adaptable for reducing environmental noises in the multifrequency system.…”

A dual-band balanced to unbalanced power divider with independent power division ratios (PDRs) at two operating frequencies is proposed in this paper. The proposed power divider includes a dual-band phase inverter, a grounded resistor, and four transmission-line sections (TLS). By simultaneously changing characteristic impedances and electrical lengths of the four TLS, the independent PDRs are obtained, and the large-signal output port at lower and upper operation bands can be different. Compared to the previous works, it has more flexibility in the power division. Moreover, the closed-form design equations are provided and discussed. To verify the proposed structure, two BTU power dividers operating at 1.0 and 2.0 GHz are designed, fabricated, and measured. The PDRs of the first power divider are-6 and 6 dB for the lower and upper operation bands, respectively. The second power divider has the PDRs of 3 and-6 dB. The measured results are good agreements with the theoretical calculation and electromagnetic simulation.

“…By loading capacitors and varactors to the coupled resonators, the features of tunable frequency were brought to the filtering power divider . In addition, the filtering power dividers, with types of balanced‐to‐balanced, balanced‐to‐unbalanced, and unbalance‐to‐balanced, were presented for the balanced‐circuit applications.…”

In this article, a wideband filtering power divider with good in-band and out-of-band isolations is designed based on a hybrid Wilkinson and Gysel structure. To achieve a good in-band response, two additional in-band transmission poles can be introduced by installing the coupled-line structures at each port. By mounting a stepped impedance open stub at the input port, two transmission zeros are generated near the passband to improve the passband skirt. Furthermore, the out-of-band rejection and isolation are achieved by the other two transmission zeros, which are produced by the open stub and the three coupled-line sections mentioned above. Additionally, a good in-band isolation is realized by the isolation resistor between output ports. For the demonstration, a wideband filtering power divider centered at 1.5 GHz with a 56% fractional bandwidth and 20-dB isolation is designed and fabricated. The simulated and measured results are in good agreement with each other. K E Y W O R D Sfiltering power divider, Gysel, isolation, wideband, Wilkinson
