Zusammenfassung:	An equivalent radio frequency (RF) notch filter, an RF chip, and a receiver are provided. The equivalent RF notch filter includes: a local oscillation (LO) circuit, configured to provide a LO frequency signal; configured to be connected in parallel with the main chain, and down-convert signals of the main chain; and a frequency selective circuit realized by impedance difference, configured to provide different impedances for down-converted signals with different frequencies from the mixing circuit, so as to absorb the signals that need to be suppressed.
