| Summary: | 碩士 === 國立臺灣海洋大學 === 通訊與導航工程學系 === 104 === RF and microwave circuit often require several different circuits, such as resonator circuit, filters, power divides, coupler, etc. If this circuits of the system are more, the losses would cause more, so we want to enhance the degree of integration and reduce losses in RF and microwave circuits. The literature shows that we can use dual-mode resonators to design bandpass filters and make the circuit downsized. This thesis is aimed at developing a design method for using dual-mode resonator bandpass filters to realize bandpass power dividers with response or characteristic like bandpass filter. Finally, we will realize three two-pole bandpass power divides, and their fractional bandwidths are 10%, 20%, 30%.
