“…There are a few papers in literature dealing with miniaturized Bagley power dividers, resorting either to shorter lines between the outputs [4,5] with slightly narrower band than a conventional one, or to composite right/left handed transmission lines, which in turn requires lumped elements [6]. Interesting possibility is also that of uneven splitters, like those in [7] or multiband ones [8].…”

A three-way power divider based on Bagley polygon is here reduced in dimension by applying the concept of reducing delay line length by applying open circuit stubs. Whereas this technique is known in literature, the delay line reduction is done symmetrically by placing the stub mid-line, which would imply packing issues leading to a reduced size reduction. In this contribution a theoretical development on non-symmetric reduced length delay line is carried out, allowing for a more effective size reduction of the Bagley-based power divider. Measurements on a prototype designed at 2.45 GHz occupying less than half of the area of a canonical Bagley divider with comparable performances over a slightly reduced operational bandwidth prove the validity of the approach.

“…Specifically, BPDs do not use lumped elements and can be easily extended to any number of output ports [2]. The development of BPDs [3][4][5][6] has advanced significantly in recent years. However, all these developments are based on single-ended types of PDs.…”

A novel balanced-to-unbalanced (BTU) Bagley power divider (BPD) with inputreflectionless filtering characteristics is proposed. It features a balanced input port and three singleended output ports, which is difficult to achieve by means of conventional BTU power dividers. The filtering characteristics are achieved by parallel coupled lines. To further improve the differential-mode filtering selectivity, stepped impedance resonators are applied to introduce two transmission zeros near the passband. The input-reflectionless characteristic in the bandstop region is achieved by loading absorptive branches. For verifying the proposed power divider topology, a prototype of microstrip BTU Bagley power divider operating at 1.0 GHz is designed and fabricated with 3-dB filtering bandwidth of 72%. Furthermore, 10-dB input-reflectionless bandwidth covers the full measurement frequency from 0 to 2.5 GHz. Good agreement between the simulation and measurement validated the proposed method.

“…For MEMS devices used in RF domains, particularly those devoted to communications and embedded electronics, planar structures are attractive than those classically developed in volume. Different topologies have been studied to improve their performances for multitude applications [1][2][3][4][5][6], particularly those based on passive components like inductors or capacitors and their associations.…”

This paper discusses the behavior of RF MEMS tunable microwave filter. We have modeled the distribution of magnetic field and electric current density in order to reveal the comportment of each device and to evaluate the relation between the frequency response and the microwave performances. From several modelling and simulations, we catch the resonance phenomenon for magnetic and electric fields at different conditions. Hence, in order to develop a reconfigurable MEMS ensuring a function of tunable band-pass filters, we have identified conditions allowing to vary the resonance frequency from Fres = 0.42 GHz to Fres = 1.85 GHz ensuring a large total variation of Tr = 340.5%. The structure is fabricated using SU-8 resin for circulating microchannels and sealing layers. The extracted parameters from measurements results and retro-simulation reveal a diminution of the total tuning range.
