| description | The invention discloses a four-local-oscillator and single-output Ku-waveband tuner. The four-local-oscillator and single-output Ku-waveband tuner comprises a V circuit (1), an H circuit (2) and a total assembling circuit (3). According to the four-local-oscillator and single-output Ku-waveband tuner, a vertical polarization signal and a horizontal polarization signal of a satellite are processed independently through the V circuit and the H circuit respectively, the V circuit comprises two superheterodyne amplification processing circuits which are a VG circuit composed of a local oscillator and a VD circuit composed of a local oscillator, the H circuit comprises two superheterodyne amplification processing circuits which are an HG circuit composed of a local oscillator and an HD circuit composed of a local oscillator, the VG circuit is parallel to the VD circuit, the HD circuit is parallel to the HD circuit, signals of the V circuit are amplified by a V combiner and a V2 intermediate frequency amplifier of |
