    Abstract: 本論文中提出結合步階式阻抗共振器(Stepped-impedance resonator, SIR)以及散佈式耦合饋入技術(Distributing coupling technique)設計而成之多頻帶多工器。
    ;The thesis presents multi-channel multiplexer and switchable multi-channel multiplexer using stepped-impedance resonator and distributed coupling technique.
    For the requirement of multi-band applications, the stepped-impedance resonators are more suitable for multiplexer than conventional impedance resonators. In order to widen stopband, the stepped-impedance resonators with different impedance ratio and electrical length ratio are employed. By the low loading effect of distributing coupling technique, it can not only increase the freedom of design but also reduce the difficulty effectively. In addition, by properly locating the pin diode to the stepped-impedance resonator, the switchable multi-band multiplexer can be achieved. Base on this structure, multi-channel multiplexer and switchable multi-channel multiplexer features wide stopband, high isolation, flexibly frequency response, and compact circuit size.
    The multi-band multiplexer and switchable multi-band multiplexer consists of distributed coupling line, bandpass filter with wide stopband, and pin diode. All of the designs, simulations, and measurements are presented and discussed in this thesis.
