This dissertation aims to design and implement
wireless passive components using domestic integrated passive device (IPD) technology. The research focuses on exploiting novel 3-D structures for various kinds of IPD-based wireless passive
components including high-quality and high-efficiency planar transformers, baluns, filters, and combiners to achieve miniature size and high performance. A
physical model has been developed for modeling the planar transformers. In this dissertation, a scalable transformer model in integrated passive device technology is further used to correlate with the coupled-line sections of a conventional Marchand balun. This improves the efficiency of the design of planar transformers with equivalent coupled-line parameters such as the coupling factor, and even- and odd-mode characteristic impedances and quality factors. Additionally, the proposed model-based
design approach provides effective optimization techniques that incorporate geometrical and material parameters. In addition, a compact transformer-based
coupled balun bandpass filter design is proposed based on integrated circuit technology and the equivalent circuit is established. Using a planar transformer with high-density fully symmetrical wiring not only greatly reduces the component size but also provides a superior stopband rejection and selectivity. Finally, by using the spiral-shaped resonators, the dual-band third-order bandpass filter has been implemented on organic substrates. The proposed BPF design is verified to overcome the elements¡¦ parasitic effects, and thus can be miniaturized and optimized with high degree of freedom. The simulation and measurement results have good agreement for
the proposed design in this dissertation.
