The invention describes a filter arrangement comprising a bandpass filter and a notch filter. The coupling of a notch filter, which consists of a capacitor and an inductor, with a bandpass filter made of resonators results in better suppression outside the pass band. By using thin-film techniques, both filters can be produced on a substrate (1) in a small space. In addition, a transmitter, a receiving device, a mobile radio device and a wireless data transmission system with such a filter arrangement and method for producing such a filter arrangement are disclosed. <IMAGE> |
