Design and realisation of filters on MHMIC and MMIC fabrication processes for duplexers realisation

In the current telecommunication environment, multimode multiband terminals are common place in transceivers architectures. These terminals integrate several radio frequency front-ends each for a different radio frequency band. Proper operation requires a separate radio frequency filter or duplexer for each band. In addition to this, filters are relatively large in size compared to other front-end components. Consequently, filters and duplexers occupy an increasing portion of modem radio frequency transceivers' real-estate. This has led the research community to dedicate more effort to filter miniaturisation techniques. This work subscribes to this context in an effort to develop miniaturised filters and duplexers with low losses and high isolation. This thesis presents a miniaturised topology based on a topological miniaturisation technique using computer aided design and analysis. The filters designed in this work are suitable for manufacturing on any planar fabrication technology such as Monolithic Hybrid Microwave Integrated Circuit (MHMIC) and Monolithic Microwave Integrated Circuit (MMIC). These specific processes were selected and used for fabrication because of their high miniaturisation and integration features. The realised filters show a significant reduction in size compared to the current state of the art. The proposed miniaturization technique, combined with multilayer fabrication technologies and other fabrication advancements, can potentially lead to filters and duplexers of reasonable sizes for monolithic integration.
