Abstract: A multi-frequency band receiver includes first and second receive paths, a combiner, a code multiplex baseband stage and an amplifier controller. The first and second receive paths receive and process first and second code multiplex signals, respectively. The first or the second receive path includes an amplifier having a variable gain factor. The combiner superposes the first and second processed code multiplex signals. The code multiplex baseband stage processes the superposed code multiplex signal to obtain and use first and second baseband receive signals. The first and second baseband receive signals represent data of the first and second code multiplex signals, respectively. In addition, the amplifier controller controls the gain factor of the amplifier having a variable gain factor so that the first or the second baseband receive signal includes a minimum reception quality which can be variably predetermined and is dependent on the operating state.

Abstract: A multi-frequency band receiver has a first path configured to process first and second frequency bands, and a second path configured to process a third frequency band, the first and second frequency bands having a smaller distance than the first and third frequency bands, and having a smaller distance than the second and third frequency bands. In addition, the multi-frequency band receiver has an oscillator stage for providing a local oscillator signal having a frequency that is between the center frequencies of the first and second frequency bands, the first path having a mixer that may be supplied with the local oscillator signal, and the second path having a mixer that may also be supplied with the local oscillator signal. In addition, the multi-frequency band receiver has a baseband stage for processing output signals of the first and second paths so as to obtain a receive signal.
