Abstract
A radio frequency (RF) receiver device comprises a receiver system that receives an analog radio frequency signal and downconverts the analog radio frequency signal to a downconverted analog signal, the receiver system further including a peak signal detector configured to determine a peak signal level of the downconverted analog signal, and an automatic gain control adjustment element configured to determine whether the peak signal level falls within a predetermined range, and configured to generate, in the RF receiver, a gain control signal controlling the gain of at least one analog component based on whether the peak signal level falls within the predetermined range.
