In the receiver, a mixer (MIX) mixes a reception signal with an oscillator signal (OOS) so as to obtain a mixer output signal (MOS), which comprises a frequency-shifted version of the reception signal.

A switchable coupling section (DBTP, SWA) is coupled between the mixer (MIX) and the intermediate frequency amplifier (IFAMP). The switchable coupling section (DBTP, SWA) is switchable to a first state and a second state. In the first state, the mixer output signal (MOS) substantially reaches an input (IAD) of the intermediate frequency amplifier (IFAMP) via a first coupling path (DTBP).

Abstract: 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 FM nor 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).

Abstract: First and second signal processing units are each configured by an IC, so that the circuit space occupying in a receiver apparatus can be reduced. The signal path can be shortened from a BPF section inputting a program signal coming from a broadcasting station to a demodulation section compared with the related art. The transmission loss on the signal path can be thus reduced compared with the related art. The possible route for noise entering from the outside to the first and second signal processing units can be made as short as possible. This enables to reduce the noise entering from the outside, and prevents the signals coming over the signal path from being attenuated by the noise so that the signal reception sensitivity can be increased.
