碩士 === 國立交通大學 === 電信工程系所 === 92 === In this project, the thin film bulk acoustic wave resonator, or FBAR, are used to design the duplexer that its receiver and transmitter is at center frequency 1.88 GHz and 1.96 GHz, and this project also design a duplexer structure that can avoid the problem during the process. In the designed procedure, the method that how to extract the FBAR equivalent circuit from its physical characteristic, would be analyzed and established in the simulation tool. This FBAR equivalent circuit can help us to design FBAR filter in the simulation tool, and improve the efficiency when it is fabricated. The method that how to design the FBAR filter with external inductors would be introduced in this project, too. The external inductor can improve the performance when we are designing the filter, so how to figure out the external inductor values and simulate FBAR with inductor would also be analyzed.
