Abstract
A band-stop filter is proposed which is constructed on a multilayered substrate and consists of a parallel circuit comprising a bandpass filter and a high-pass filter. The two filters are at least partly realized in the form of LC-elements integrated into the substrate. Further circuit components can be arranged as discrete components on the substrate. In the filter branch having the bandpass filter, an electroacoustic resonator is arranged in a transverse branch to ground. By means of the filter, a wide stop band is obtained, while the passband or passbands can comprise a plurality of radio bands.
