Abstract
A radio frequency receiver and an automatic gain control method of the radio frequency receiver is presented. The radio frequency receiver includes an automatic gain control apparatus, a radio frequency component, and an analog to digital converter, where the automatic gain control apparatus further includes: an intensity calculator configured to calculate a relationship between an intensity representation parameter of digital data and a preset intensity threshold within a preset calculation time; and an automatic gain controller configured to compare the relationship calculated by the intensity calculator with a preset relationship threshold, and adjust a gain of the radio frequency component on radio frequency data according to a comparison result, so that an amplitude of the radio frequency data obtained after the gain adjustment is within a receiving range of the analog to digital converter.
