ABSTRACT:
A filter (102) with an adjustable bandwidth. The filter (102) has a predetermined passband and stopband, and an input (104), an output (106) and at least two resonator structures (116, 124), and a variable reactance element (108) for adjusting the bandwidth of the passband, coupled between the resonator structures (116, 124), whereby the frequency response is adjustable.
