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.
