Within the limited-size platform of radio frequency system in package (RF-SIP), how to effectively construct the function embedded new filtering network in three dimensional scale is not only an extremely challenging basic research topic but also an important issue need to be solved immediately for high performance wireless communication system, since it can obviously reduce the packaging size and degrade the design complexity while maintaining the high operation performance for system. In this context, the motivation of this project is to study the new modeling method and its application for the function embedded filtering networks on the basis of three-dimensional low temperature co-fired ceramic (LTCC) packaging technology. By combining the matrix rotation similarity transformation method with the quantum particle swarm optimization method, the coupling and routing topologies of function embedded filtering networks can be efficiently and exactly optimized from the viewpoint of global analysis and searching. The main contents include: research on high efficiency and accuracy modeling and analyzing method for coupling topologies of multi-port filtering networks, research on new function embedding techniques and methods in the filtering network, and the design of new function embedded filtering components in LTCC. It’s our belief that the achievements developed by the research of this project are bound to supply reliable principle guidelines for function embedded filters in RF-SIP, efficient and accurate design method, optimized coupling and routing topologies, and umpty initial models verified by both theoretical and experimental, which is promising to provide high value technical reserves for the development of wireless communication technology in our country.
