摘要
The present invention reveals a novel topology composed of BAW CRFs (Bulk Acoustic Wave Coupled Resonator Filters) that offers a controllable band suppressor. Although BAW CRFs have a natural bandpass behavior, a convenient arrangement of these devices can provide a band suppressor response, the present invention is based on the creation of a direct path between the input and output ports offered by a transmission. complete signal and the addition of BAW CRFs in parallel to the direct path, so that they absorb energy in the specified rejection band.
