  • Patent number: 8023922
    Abstract: Receivers (5) for simultaneously receiving different radio frequency signals according to different standards are provided with first frequency translating stages (1) for converting the radio frequency signals into first intermediate frequency signals and second frequency translating stages (2) for converting the first intermediate frequency signals into second intermediate frequency signals and processing stages (3) for retrieving first information from the first intermediate frequency signals and second information from the second intermediate signals. As a result, such receivers (5) have relatively low power consumption. The first frequency translating stages (1) comprise first oscillators (19) and first mixers (11) and further first mixers (12). The second frequency translating stages (2) comprise second oscillators (29) and second mixers (21) and further second mixers (22) and third mixers (23) and further third mixers (24).
