Abstract
A radio frequency receiving circuit includes a first amplification circuit, an oscillation circuit, a frequency mixing and amplification circuit and a dividing circuit. The first amplification circuit is configured to amplify an input signal so as to generate an amplified input signal. The oscillation circuit is configured to provide a local oscillation signal. The frequency mixing and amplification circuit is configured to mix and amplify the amplified input signal according to the local oscillation signal. The dividing circuit is configured to form a dividing loop at a preset frequency for the amplified input signal according to the local oscillation signal when the dividing circuit is driven. A chip including the radio frequency receiving circuit and a main circuit is also provided. The main circuit is configured to drive the dividing circuit when the second input signal is determined to include a signal of the preset frequency.
