In the proposed project, efficient and accurate design and modeling techniques will be developed for advanced filters and multiplexers, which find wide applications in space and ground based communications systems. Canadian wireless and satellite industry is facing intense competition worldwide. The advancement of computer aided design (CAD) technologies is vital for the industry to stay competitive and keep pace with technology innovations. The proposed research project targets the latest developments in advanced filter technologies, which play an important role in current and future generation satellite systems. The outcomes are expected to be fully automated design process capable of shorting the design cycle, which is indispensable for manufacture-oriented large-scale design problems; efficient modeling techniques that enables iterative optimization of designs and accurate characterization of the filter/multiplexer behavior, which is critical in ensuring success on the hardware level, shortening production cycle and cost reduction; systematic multiplexer design approach to facilitate the design of multiplexers with significant performance enhancement, which provides the industrial partner with a competitive edge against its non-Canadian competitors. The proposed research is expected to make significant contributions in the field of CAD and RF/microwave filter/multiplexer technologies, both from theoretical point of view, and from practical applications in solving product design and manufacture problems faced by the industry. The design tools and methodologies developed in the project will be instrumental to ensure first-pass success, speed up design and production cycles, and achieve designs with much improved performance. The outcome from the project will therefore enhance competitiveness and capability of the Canadian high-tech telecommunications industry, including the industrial sponsor, in the global market.
