A novel multilayer dual-mode filter based on substrate integrated hexagonal cavity (SIHC) that supports two degenerated modes is demonstrated. The proposed filter is composed of a modified extended-doublet. By profit from two coupled dual-mode hexagonal cavity and asymmetry feeding structure, three transmission zeros (TZs) are generated. Accordingly, the filter not only has good selectivity due to...

This paper describes the realization of high performance millimetre-wave substrate integrated waveguide (SIW) components and integrated compact RF front-end modules using photoimaged trench vias on advanced multilayer thick-film technology. Contrary to widely used SIW with fence-post vias, advanced trench-filled vias form continuous metal (silver) side walls, enabling SIW to provide low loss and extending...
A novel high-performance millimeter-wave multilayer dual-mode filter is developed based on the substrate integrated waveguide circular cavity (SICC). The filter with two or three SIW circular cavities has been designed for Ka-band application. The multilayer dual mode filter has been firstly realized only by adjusting the coupling aperture located in input/output port and between layers. The position...
In this paper, efficient physics-based models are used to examine diverse differential and single-ended link configurations on multilayer substrates with mixed reference planes (i.e. links running between ground and power planes). The effect of different plane assignments is studied and the results are validated with a general purpose full-wave solver. It is shown that the plane configuration affects...
In this paper, a novel compact X-Band band pass filter (BPF) with low loss and narrow-band using low temperature co-fired ceramic (LTCC) technology is proposed. This four pole filter is based on substrate integrated circular cavity (SICC) resonators, and the slots excitation with lambda/4 open stub is used here. This filter with simple structure exhibits an insertion loss of 0.66dB at center frequency...
This paper presents new experimental and numerical methods to characterize the transfer overmolding of substrates with epoxy polymer. We investigated Multi Chip Modules on ceramic panels as well as on printed circuit boards encapsulated by a MAP-type molding process. Experiments show that the polymer flow during the overmolding process depends significantly on the mold height: While standard MAP-type...
