Download or read book Microwave Bandpass Filters for Wideband Communications written by Lei Zhu and published by John Wiley & Sons. This book was released on 2011-12-28 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will appeal to scientists and engineers who are concerned with the design of microwave wideband devices and systems. For advanced (ultra)-wideband wireless systems, the necessity and design methodology of wideband filters will be discussed with reference to the inherent limitation in fractional bandwidth of classical bandpass filters. Besides the detailed working principles, a large number of design examples are demonstrated, which can be easily followed and modified by the readers to achieve their own desired specifications. Therefore, this book is of interest not only to students and researchers from academia, but also to design engineers in industry. With the help of complete design procedures and tabulated design parameters, even those with little filter design experience, will find this book to be a useful design guideline and reference, which can free them from tedious computer-aided full-wave electromagnetic simulations. Among different design proposals, wideband bandpass filters based on the multi-mode resonator have demonstrated many unparalleled attractive features, including a simple design methodology, compact size, low loss and good linearity in the wide passband, enhanced out-of-band rejection, and easy integration with other circuits/antennas. A conventional bandpass filter works under single dominant resonant modes of a few cascaded transmission line resonators and its operating bandwidth is widened via enhanced coupling between the adjacent resonators. However, this traditional approach needs an extremely high coupling degree of coupled-lines while producing a narrow upper stopband between the dominant and harmonic bands. As a sequence, the desired dominant passband is restricted to an extent less than 60% in fractional bandwidth. To circumvent these issues and break with the tradition, a filter based on the multiple resonant modes was initially introduced in 2000 by the first author of this book. Based on this novel concept, a new class of wideband filters with fractional bandwidths larger than 60% has been successfully developed so far. This book, presents and characterizes a variety of multi-mode resonators with stepped-impedance or loaded-stub configurations using the matured transmission line theory for development of advanced microwave wideband filters.

Download or read book Microwave Rf Filters Based on Bulk Acoustic Wave Resonators written by Jordi Verdú and published by LAP Lambert Academic Publishing. This book was released on 2011-12 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: The exponential growth in wireless communication systems in recent years has been due to the requirements of small high performance microwave/RF devices and filters in particular. The main limitation of microwave devices based on traditional technologies is that these technologies are not compatible with the manufacturing process of standard integrated circuits (IC). Microwave devices based on acoustic resonators, and bulk acoustic wave (BAW) resonators in particular, overcome this limitation since this technology is compatible with standard IC technologies. On the other hand, BAW resonators are excited by means of an acoustic wave with lower propagation velocity than that of electromagnetic waves, leading to the size reduction of the resonator and the microwave device as a consequence. Taking into account the physical characteristics of the acoustic material, the design procedure for basic microwave/RF filters is discussed, and also the way to improve the their electrical performance. Aftewards, new filter topologies are presented to achieve more sophisticated responses, in particular a dual-band transmission response.

Download or read book Compact Bandpass Filters Using Dual mode Microstrip Closed loop Ring Resonators for Wireless Communication Systems written by Babak Kazemi Esfeh and published by . This book was released on 2009 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microwave filters have important role in many wireless and communication systems such as satellite and cellular mobile organizations. In such kind of systems, factors such as compact size, low cost, light weight, high performance, and low loss in designing of microwave filters are of primary importance. In comparison with waveguide filters, microstrip filters are smaller and in such applications mentioned before there are needs to have smaller microstrip filters. In this thesis, filters using dual-mode ring resonators is proposed, because they can be designed easier than the other kind of microwave filters and are more compact. In this thesis, a new compact form of dual-mode microstrip octagonal loop resonator filter is proposed in two forms; conventional and compact. These structures are designed to operate at WiMax frequency of 2.3 GHz with a 5% fractional bandwidth. The new dual-mode resonator will be produced by adding a rectangular patch inside the loop resonator. The experimental results and simulated values are presented and show good agreement. The filter is fabricated on CER-10 substrate having a relative dielectric constant of 10 and 0.64 mm thickness. The primary dimension of the filter is 15.8 mm x 15.8 mm and the measured minimum insertion loss is 1.68 dB and return loss is better than -20 dB. After minimization and compressing the filter structure, the final dimension is reduced to 9.1 mm x 9.1 mm. The minimum insertion loss in this structure is 1.52 dB and the return loss is better than -20 dB. In the final design in addition to size reduction (about 42%), feed lines structure is changed from orthogonal to straight line form, which are more desirable in microwave networks. This new design is reduced in size by approximately 25% compared to the conventional square loop dual-mode filter. By using meander square loop structure more reduction in size (about 27%) can be achieved but this filter configuration has a weak frequency response including high passband insertion loss (more than 2.6 dB) and return loss less than -12 dB at the same center frequency. Therefore its performance is less than the dual-mode filter proposed in this thesis. Apart from WiMax, this model of filters is also useful for WLAN and mobile communication applications, because it is compact in size, low loss and has good performance due to its elliptic response with sharp and adequate fractional bandwidth.

Download or read book Low Loss VHF and UHF Filters for Wireless Communications Based on Piezoelectrically Transduced Micromechanical Resonators written by Julio Mario Dewdney and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: For the past decade, a great deal of research has been focused towards developing a viable on-chip solution to replace the current state-of-the-art VHF and UHF filters based on SAW and FBAR technologies. Although filters based on SAW and FBAR devices are capable of fulfilling the basic requirements needed for IF and RF bandpass filtering and reference signal generation, an alternative solution that can enable the next generation of multi-frequency and multi-mode transceivers while enabling size and price reduction by allowing the manufacturing of single-chip monolithic RF transceivers is highly desired. In response to these new needs, piezoelectrically-transduced micromechanical filters have emerged as a plausible alternative to outperform current dominant technologies in size, cost, and IC manufacturing compatibility without compromising device performance in terms of insertion loss, rejection, power handling and linearity. This dissertation presents the design, fabrication, characterization and experimental analysis of low-loss VHF and UHF filters for wireless communication applications, based on piezoelectrically-transduced micromechanical resonators. The resonators employed in this work for the implementation of microwave filters, resonate in contour-mode shapes, which differ from commercially available thickness-mode FBAR resonators, for which the thickness sets the resonance frequency. The employment of contour-mode designs facilitate simultaneous synthesis of multiple frequencies on the same substrate through CAD layout-defined lateral dimensions, thus avoiding the complexity demanded by FBAR devices for the precise control of the piezoelectric layer thickness.

This book was released on 2008-09-26 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microwave dielectric materials play a key role in our global society with a wide range of applications, from terrestrial and satellite communication including software radio, GPS, and DBS TV to environmental monitoring via satellite. A small ceramic component made from a dielectric material is fundamental to the operation of filters and oscillators in several microwave systems. In microwave communications, dielectric resonator filters are used to discriminate between wanted and unwanted signal frequencies in the transmitted and received signal. When the wanted frequency is extracted and detected, it is necessary to maintain a strong signal. For clarity it is also critical that the wanted signal frequencies are not affected by seasonal temperature changes. In order to meet the specifications of current and future systems, improved or new microwave components based on dedicated dielectric materials and new designs are required. The recent progress in microwave telecommunication, satellite broadcasting and intelligent transport systems (ITS) has resulted in an increased demand for Dielectric Resonators (DRs). With the recent revolution in mobile phone and satellite communication systems using microwaves as the propagation media, the research and development in the field of device miniaturization has been a major challenge in contemporary Materials Science. In a mobile phone communication, the message is sent from a phone to the nearest base station, and then on via a series of base stations to the other phone. At the heart of each base station is the combiner/filter unit which has the job of receiving the messages, keeping them separate, amplifying the signals and sending then onto the next base station. For such a microwave circuit to work, part of it needs to resonate at the specific working frequency. The frequency determining component (resonator) used in such a high frequency device must satisfy certain criteria. The three important characteristics required for a dielectric resonator are (a) a high dielectric constant which facilitates miniaturization (b) a high quality factor (Qxf) which improves the signal-to-noise ratio, (c) a low temperature coefficient of the resonant frequency which determines the stability of the transmitted frequency. During the past 25 years scientists the world over have developed a large number of new materials (about 3000) or improved the properties of known materials. About 5000 papers have been published and more than 1000 patents filed in the area of dielectric resonators and related technologies. This book brings the data and science of these several useful materials together, which will be of immense benefit to researchers and engineers the world over. The topics covered in the book includes factors affecting the dielectric properties, measurement of dielectric properties, important low loss dielectric material systems such as perovskites, tungsten bronze type materials, materials in BaO-TiO2 system, (Zr,Sn)TiO4, alumina, rutile, AnBn-1O3n type materials, LTCC, ceramic-polymer composites etc. The book also has a data table listing all reported low loss dielectric materials with properties and references arranged in the order of increasing dielectric constant.
