    摘要： A front-end circuit with a tunable filter is disclosed. In an embodiment, the front end circuit includes a first signal path connected to an antenna connection, a first filter arranged in the first signal path, wherein the first filter is tunable within a first frequency range, and an extra signal path and a first fixed filter arranged therein, wherein the first fixed filter has a passband for an extra frequency band, wherein the first fixed filter is not tunable, and wherein the extra frequency band is arranged outside or inside the first frequency range. The front end circuit further includes a narrowband antenna tuner configured to be set to a respective tunable frequency range, wherein the narrowband antenna tuner is arranged between the first filter, the first fixed filter and the antenna connection in the first and second signal paths.
