Abstract: The invention proposes an LNB using two transposition frequencies chosen on either side of the reception band 200 so as to obtain a transposition of supradyne type 205 and a transposition of infradyne type 204 according to the frequency used. This choice of transposition frequencies makes it possible to have an overlap zone 202 in the middle of the reception band which is transposed with the aid of the two oscillation frequencies but at different frequencies. This makes it possible to choose between the two transpositions in the case where the frequency transposed with the aid of an oscillator corresponds to a particularly noisy frequency.

Abstract: The invention relates to a receiver 1 of signals and proposes to remedy a non-linearity problem in an amplifier 70 of an integrated tuner 7. A linearity compensation circuit 8 is inserted upline from the tuner 7. The compensation circuit 8 presents a characteristic that is the inverse of the characteristic of the low-noise amplifier 70 in order to compensate for the linearity defect.

Abstract: The receiver has a band pass filter (6) allowing passage of signals with intermediate frequency band, and performing impedance matching with a coaxial cable (5). An integrated tuner (7) including a low noise amplifier (70) is connected to the filter. A compensation circuit (8) placed between the tuner and the filter has transfer characteristics inverse to that of the amplifier in the intermediate frequency band. The circuit comprises a series arrangement of a resistor (80), microstrip inductor (81) and a capacitor (82).

Abstract: A Multi-tuner reception system includes at least a first tuner and a second tuner. The first tuner is adapted to translate a frequency of a first received signal into a first translated frequency. The first tuner includes a first local oscillator operating at a first local oscillator frequency. The second tuner is adapted to translate a frequency of a second received signal into a second translated frequency. The second tuner includes a second local oscillator operating at a second local oscillator frequency. The second local oscillator frequency is equal to a sum of the first local oscillator frequency and a continually time variable offset frequency.
