Abstract: A multiband receiver and associated method are provided for simultaneous reception of a number of RF signals with partially different carrier frequencies. An RF/IF converter is provided with a number of local oscillators corresponding to a number of RF signals in order to produce L0 in phase components corresponding to the carrier frequencies and quadrature components; in addition to an in-phase mixer and a quadrature mixer for mixing the respective L0 in-phase and quadrature components with the RF signals in order to produce intermediate frequency signals with IF in-phse components and IF quadrature components. A complex fiber carries out complex filtering on the basis of the intermediate frequency signals in order to suppress reflected intermediate frequency signals.
