摘要
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.
