Abstract
We present a tunable bandpass filter in parallel structure in comparison to a tunable filter in serial structure. The filters are tunable in bandwidth with a constant center frequency. The investigations are based on coupled-resonators bandpass filters. The approach of a parallel topology can be adopted for filter tunable in the center frequency, allowing for a fully tunable frequency response.
