ARCHITECTURE DE RECEPTEUR RADIO VERSATILE

The invention concerns an RF receiver comprising: a down-converting and sampling circuit (104) adapted to: receive an RF input signal (RF IN ) having a signal band (BW RF ) comprising a plurality of sub-bands (BW IF ), each sub-band comprising a plurality (2K) of channels separated by frequency channel spaces (”f CH ); and perform frequency transposition and sampling to generate a discrete time signal in which a selected one of the plurality of sub-bands is brought from an initial frequency band to a lower frequency band (IF2 0 ±K”f CH ); and a discrete time filter (108) having a variable pass band, the central frequency (f 0 ) of the discrete time filter being controllable to select any one of the plurality (2K) of channels of the selected sub-band.
