The present invention relates to a combination RF tuner capable of receiving signals from the FM radio band and from the TV band. Prior art combination tuners had to compromise in quality resulting in combination tuners that neither exhibited high-end FMnor TV-signal reception behavior. A combination RF tuner capable of optimal receiving an FM-radio signal type and a TV signal type, comprising a switch-able tuned input filter (440), is proposed. One response of the input filter (440) provides a sufficient big bandwidth for enabling reception of the TV-signal type. The input filter (440) of the invention can be switched, providing a second response that has a smaller bandwidth for enabling reception of the FM-radio signal type. The second response can be realized by substantially bypassing an 10 inductive element (450) (e.g., comprising a inductor, L21, in series with a damping resistor, R3) of the input filter (440).
