Zusammenfassung:Disclosed is a variable bandwidth RF filter. The disclosed filter comprises: a first filter unit having a first bandwidth and a variable-frequency structure; and a second filter unit having a second bandwidth and a variable-frequency structure. The first filter unit and the second filter unit are coupled to a cascade structure, and the bandwidth is adjusted by varying the frequency of the first filter unit and of the second filter unit. The disclosed filter is advantageous in that the variation of the bandwidth can be easily performed using a simple structure.
