Abstract

The present invention discloses a radio frequency receiver and a receiving method, where the method includes: performing band splitting on a radio frequency signal of multiple carriers to obtain at least one band signal, and outputting the signal; separately performing filtering and amplification processing on the at least one band signal to obtain at least one processed signal; generating multiple oscillation signals; and selectively receiving a processed signal, of the at least one processed signal, that includes a target carrier; receiving an oscillation signal corresponding to the target carrier; selectively selecting a frequency division ratio from multiple frequency division ratios; using the frequency division ratio to perform frequency division on the received oscillation signal to obtain a local oscillator signal; using the local oscillator signal to perform frequency mixing on the received processed signal that includes the target carrier to obtain a mixed signal.
