摘要： A switchable microstrip quad-band bandpass filter (BPS) is investigated in this study. Owing to the low loading effect from distributed coupling technique, many channels can be obtained without the requiring of complicated matching network. Each passband can be turned on and off independently. The switchable quad-band BPS consisting of half-wavelength/quarter-wavelength resonators, loaded open stubs and p–i–n diodes features compactness and good selectivity. To validate this design concept, theory as well as experiment is presented and compared in this study. 出版者： Stevenage: The Institution of Engineering and Technology 出版日期： 2013-11 出處： IET microwaves, antennas & propagation, 2013-11, Vol.7 (14), p.1113-1119 資源來源： Wiley Online Library Journals [OA] Open Access 版權： The Institution of Engineering and Technology 版權： 2013 The Institution of Engineering and Technology 版權： 2014 INIST-CNRS 版權： Copyright The Institution of Engineering & Technology Nov 2013 識別號： ISSN: 1751-8725 識別號： ISSN: 1751-8733 識別號： EISSN: 1751-8733 識別號： DOI: 10.1049/iet-map.2013.0077
