“…This configuration has good isolation between two output ports but also has a large size because the resonators work at second-order resonance. In our previously research [24], the BTB filtering power divider was realized by half-wavelength resonator and short-stub-loaded resonator (SSLR). Compared with the research proposed in [22], it achieved compacter size and wider suppression for the common-mode signal.…”

This paper presents the balanced-to-balanced Gysel filtering power divider with arbitrary power division for first time. Based on the multicoupled series-resonator bandpass prototype network, a detailed theory analysis is presented and the corresponding design equations are concluded. Two filtering power dividers with the division ratio of 2 and 3 are realized using the half-wavelength resonator and the short-stub-loaded resonator. Finally, two example circuits are fabricated and measured for verification. The measured results show good agreement with the simulated and confirm the theory.

“…At low frequencies, these devices occupy very large area; so a lot of research is being done to miniaturize these devices. But, most of this research work is based on microstrip and coplanar waveguide technologies, which have their limitations regarding the power handling capacity of the devices [1][2][3][4][5]. Whereas, substrate integrated waveguide (SIW) based devices offer low losses, provide more power handling capacity and are easy to be integrated with planar circuits.…”

A novel compact 4-way power divider is presented here, which consists of 1/64 th mode elliptically curved substrate integrated waveguide (SIW) resonators and radial transmission lines. A direct coaxial fed circular patch acting as a radial transmission line is connected with four elliptically curved 1/64 th mode SIW resonators, and these resonators are then connected to output terminals. An equivalent circuit model is developed to understand its behavior. It is designed to operate at 3.6 GHz covering the frequencies assigned for 5G in sub-6 GHz band. Conventional PCB techniques are used to fabricate the prototype. The measured bandwidth is 2.2 GHz, ranging from 2.5 GHz to 4.7 GHz, for which the return loss is less than −10 dB. Also, the transmission coefficient between input and each output for the above-mentioned frequency band is −6.4 ± 0.5 dB. It has a very compact footprint of 0.32λ 2 g , which is at least 40% smaller than various SIW based state of the art power dividers.

“…With the rapid development of high‐speed electronic systems in recent years, balanced/differential circuits have attracted plenty of attention due to their excellent performance compared with the single‐end counterparts. In order to build up fully balanced transceivers, various balanced passive components have been proposed, such as balanced‐to‐balanced (BTB) filters and couplers 1‐3 …”

In this article, a balanced‐to‐balanced (BTB) ultra‐wide band (UWB) power divider (PD) is proposed, which can realize arbitrary power‐dividing ratio (PDR) with improved transmission bandwidth flatness. The proposed PD is primarily based on microstrip/slotline (MS) transition structures and parallel‐coupled three‐slotline structure. U‐type microstrip feed lines integrated with stepped‐impedance slotline resonators are adopted at the input and output ports, which make the differential‐mode (DM) responses independent of the common‐mode (CM) ones. Meanwhile, superior DM transmission and CM suppression are achieved intrinsically, thereby simplifying the design procedure significantly. By changing the distances between the coupled three slotlines, the PDR between the output ports is controllable. In order to verify the feasibility of the proposed design method, several prototype circuits of the proposed PDs with different PDRs are simulated and a prototype circuit with the 2:1 PDR is fabricated and measured. A good agreement between the simulation and measurement results is observed.
