摘要： Two switchable microstrip bandpass circuits are investigated. Owing to the low loading effect from the distributed coupling technique, many channels are obtained without a complicated matching network. Each passband can be turned on and off independently. Both the bandpass single-pole quadruple-throw switch and the switchable quadruplexer consisting of asymmetrical quarter-wavelength resonators, shunt open stubs and p-i-n diodes feature compactness, high isolation and wide stopband. The isolation is better than 35 dB, and the 20-dB stopband extends up to 13 times of the lowest operation centre frequency. To validate this design concept, theory as well as experiment are presented and compared. 出版者： Stevenage: The Institution of Engineering and Technology 出版日期： 2014-03 出處： IET microwaves, antennas & propagation, 2014-03, Vol.8 (4), p.244-254 資源來源： Wiley Online Library Open Access 版權： The Institution of Engineering and Technology 版權： 2014 The Institution of Engineering and Technology 版權： 2015 INIST-CNRS 版權： Copyright The Institution of Engineering & Technology Mar 2014 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.2013.0198
