This paper develops a novel ultra-wideband bandpass filter by cascading a broadband bandpass filter with another broadband bandstop filter. Properly selected impedances of transmission lines achieve broadband bandpass and bandstop filters and make independent designs possible. Detailed design and synthesis pr...
Compact, low insertion-loss, sharp-rejection, and wide-band microstrip bandpass filters A new bandpass filter based on the bandstop filter uses two tuning stubs to construct a wide-band passband with two sharp stopbands. Without coupling ... LH Hsieh,C Kai - 《IEEE Transactions on Microwave ...

A tunable, substrate integrated, high Q bandpass-bandstop filter cascade is demonstrated that is capable of providing up to 100 dB of isolation between two dynamically selectable frequencies of interest. Evanescent-mode cavity filters are used in the cascade to allow high quality factors and wide tu...
A circuit for differential wideband bandpass filter (BPF) is presented. The circuit works as a bandpass and bandstop filter under differential- and common-mode excitation, respectively. Under differential-mode, two transmission zeros are generated by the short-ended parallel-coupled stubs and supply ...
The center frequency is 1.575 GHz, and the 1 dB relative bandwidth is 6.3%. The narrowband filters are cascaded with two bandstop filters to design a new bandstop filter. The resultant filter has three zeros in the high rejection band. It provides excellent blocking characteristics, achieving a...

The proposed filter is based on the design of a bandpass filter cascaded with a defected microstrip structure (DMS) bandstop filter. The bandstop characteristic is realized using T-shaped DMS at the external input and output coupling transformers. The measured and simulated electrical performances are...
