Embodiments of the present invention provide a receiver and a receiving method of the receiver, so that monolithic integration of multiple receiving channels can be implemented. The receiver includes: a zero intermediate frequency channel, performing in-phase/quadrature (IQ) down conversion on a radio frequency signal at a first frequency band using a frequency division or frequency multiplication signal of a first oscillation signal; and a superheterodyne channel, performing down conversion on a radio frequency signal at a second frequency band using the frequency division or frequency multiplication signal of the first oscillation signal, where the first frequency band is different from the second frequency band. According to the embodiments of the present invention, a zero intermediate frequency channel and a superheterodyne channel use a same oscillation signal or a same frequency division or frequency multiplication signal of the oscillation signal, thereby monolithic integration of multiple receiving channels can be implemented.
