“Boosting better decisions during early design stages based on synthesis methodologies for acoustic wave filters. ”

With a spectrum more and more overcrowded, the design of filtering modules for end-user terminal is becoming a challenging task. The major reasons are stringent transmission response and a very restrictive AW technology. Moreover, new released bands in the 5G framework demand for filters operating at higher frequencies with larger bandwidths. The systematic synthesis methodology to design analytically a ladder-type filter based on acoustic wave resonators will be reviewed. Although this configuration has been the workhorse in the conventional filter design, mainly for the sub-6GHz applications, it is a rigid configuration which may limit the range of achievable filtering functions. It will be shown how the development of new synthesis methodologies may enable new advanced filtering functions and topologies to break with very-well stablished paradigms. The understanding of the input phase role is crucial to this aim, allowing allows responses with improved rejection/selectivity and technologically feasible solutions based on reduced Chebyshev responses. These new synthesis methodologies have been able to face the design of more complex structures providing multi-band responses, accommodating the technological constraints set by the acoustic wave technology. This procedure is time efficient, precise in the outcomes, and provides a deep understanding of orthogonal interactions between technology constraints and device performance..

From 2006 to 2010 he was a member of the Antenna and Microwave Systems (AMS). In 2010 he joined the RF System Group at the European Spallation Source in Bilbao (ESS-B) as a group coordinator. In 2011-2012 he was at the École Polytechnique Fédérale de Lausanne through a Marie Curie grant. In 2013 he joined the Theory Signal Communication group at Universitat Politècnica de Catalunya. Currently, he is an Associate Professor at the Universitat Autònoma de Barcelona where he teaches microwave engineering courses, and member of the WavesLab Group. He is a member of the MTT-6 MEMS and Microwave Acoustics Technical Committee. He has been extensively working on linear modelling of acoustic wave devices, and new synthesis techniques and advanced configurations for acoustic wave filters. His current research interest includes the design of microwave devices and linear modelling, but also the design of active devices for Space applications..

Microwave Filters – Past, Present and Future An industry view”

High performance microwave filters are critical, performance defining components of modern space and terrestrial communications systems. The history of advances in this technology field is well documented and spans more than seventy years. In my talk, this will be discussed based on my personal involvement in this technology for a period of almost sixty years. Starting with Ragan’s book, articles by Seymour Cohn and Ralph Levy and Matthaei’s book we will move to what I consider the “Golden Era “of microwave filter technology driven by needs of communications satellite industry. Significant advances in this technology such as novel implementations, filter network synthesis, EM simulations, fabrication techniques and high-power filters, to name a few, will be discussed. The impact of development of temperature stable, high dielectric constant materials, discovery of high temperature superconductive ceramics and MEMS technology will also be discussed. By year 2000, communications satellite filter and multiplexer technology matured and filter development shifted toward wireless terrestrial communications systems, which are constantly moving to higher frequencies for wider bandwidth availability This presents additional challenges for filter industry such as low cost fabrication techniques, new materials etc.. In conclusion, the future of microwave and now, millimeter wave filter technologies will be discussed. .


Slawomir Jerzy (Jerry) Fiedziuszko (Life Fellow IEEE 2009) received MSEE degree with distinction from Warsaw University of Technology in 1967. His master thesis “ Computer Optimization of MASER Resonators” was published in prestigious Bulletin of Polish Academy of Sciences. After graduation he was a first to be enrolled in accelerated doctoral degree pilot program at Institute of Electron Technology Polish Academy of Sciences. His doctoral dissertation subject “ Microwave Resonators and Filters with High Dielectric Constant Materials” required extensive computer calculations since no analytical solutions were available for resonators filled with anisotropic materials. Inspired by Matthaei’s book he started to design microwave filters using computers. One of the computer design programs published in Archiwum Elektrotechniki was for microwave coaxial lowpass filters. In this computer program as input were electrical and mechanical specifications and output was mechanical dimensions of the filter( simple CAD program). He also designed pin diode switches and tried to stabilize IMPATT diode oscillator with Rutile dielectric resonator. He was a first from Poland to have his work published in MTT Transactions. In 1971 he moved to United States. Initially, he started work at Radar Design Corporation in Syracuse NY and was an Adjunct Professor at Syracuse University. In 1979 he moved to California and started work at Ford Aerospace in Palo Alto (later Space Systems/LORAL) where he developed dielectric resonator filters and high power multiplexers for communication satellites. In 2003 he joined Lockheed Martin CSS. In 2008 he worked for COMDEV USA as VP of Engineering. Overall, his enabling inventions were flown on more than 200 GEO communications and direct broadcast satellites and more than 100 LEO satellites . He significantly contributed to GPS and GOES weather satellite programs. He has published more than 100 journal and conference papers and has more than 40 patents to his credit, He is a Life Fellow of IEEE, Fellow of IAAA, and he is a recipient of the IEEE Third Millennium Medal. He received a numerous awards including Microwave Applications Award “ For the development of dual-mode dielectric loaded cavity filters” and Aerospace Laurels Award from Aviation Week. .
