Abstract
An RF receiver includes a variable gain amplifier which amplifies a received RF signal based on a gain control signal, a peak detector which determines a peak value of the amplified signal, a mixer which downconverts the amplified signal to a downconverted signal, and a control unit which determines whether or not an interfering signal other than an adjacent channel interfering signal is received. If the control unit determines that the interfering signal other than the adjacent channel interfering signal is received, the control unit generates the gain control signal so that the range of the peak value is a first range; otherwise, the control unit generates the gain control signal so that the range of the peak value is a second range. The upper and lower bounds of the second range are lower than the upper and lower bounds of the first range, respectively.
