FIELD: radio engineering, communication.
SUBSTANCE: 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 length than the first and third frequency bands, and having a smaller length than the second and third frequency bands. In addition, the multi-frequency band receiver has a heterodyne/oscillator for providing a heterodyne signal having a frequency that is between the centre frequencies of the first and second frequency bands, the first path having a mixer that may be supplied with a heterodyne signal, and the second path having a mixer that may also be supplied with a heterodyne signal. In addition, the multi-frequency band receiver has a baseband for processing output signals of the first and second paths so as to obtain an input signal.
EFFECT: providing a multi-frequency band receiver for processing signals with more than two frequency bands, which requires few components and has low current consumption.
