This invention discloses a frequency conversion circuit, a wireless communication circuit, an apparatus, a system, and a method. The technical solution of this invention, through optimization and improvement of existing passive frequency conversion circuits, can further reduce costs. Furthermore, by directly feeding the broadband noise signal into the resonant unit from the second modulation port without other loss circuits, the path loss of the broadband noise signal can be reduced, thereby obtaining more oscillation signals. This allows more oscillation signals to be fed into the modulation element for mixing, ultimately resulting in more frequency conversion signals. In other words, with the same initial radio frequency signal power, the frequency conversion circuit can produce more frequency conversion signal power, correspondingly reducing the power consumption of the frequency conversion circuit and achieving a longer wireless operating distance.
