Patent ID: 8306154

Claim:
A multi-frequency band receiver, comprising: a first path configured to process a first frequency band and a second frequency band; a second path configured to process a third frequency band, the first frequency band and the second frequency band exhibiting a smaller distance than the first frequency band and the third frequency band, and exhibiting a smaller distance than the second frequency band and the third frequency band; an oscillator stage for providing a local oscillator signal comprising a frequency that is between the center frequency of the first frequency band and the center frequency of the second frequency band, the first path comprising a mixer that is supplied with the local oscillator signal, and the second path comprising a mixer that is supplied with the local oscillator signal; a baseband stage for processing output signals of the first path and output signals of the second path so as to acquire a receive signal, wherein the first path comprises an in-phase output and a quadrature-phase output, wherein the second path comprises an in-phase output and a quadrature-phase output, and wherein the baseband stage comprises an in-phase input and a quadrature-phase input; and a combiner configured to superimpose a signal at the in-phase output of the first path and a signal at the in-phase output of the second path and to make said signal available to the baseband stage at the in-phase input, and the combiner being configured to superimpose a signal at the quadrature-phase output of the first path and a signal at the quadrature-phase output of the second path and to make said signal available to the baseband stage at the quadrature-phase input.
