Abstract: A receiver includes at least a first amplifier configured to receive a received signal and provide a first amplified signal based thereon, a mixer configured to receive the first amplified signal and provide an intermediate frequency signal based thereon and a second amplifier configured to receive the intermediate frequency signal and provide a second amplified signal based thereon. An automatic gain controller for the receiver is configured to, based on a first overload signal indicative of a first frequency range of the first amplified signal having one or more frequency components exceeding a first maximum signal power threshold and a second overload signal indicative of a second frequency range, narrower than the first, of the second amplified signal having one or more frequency components exceeding a second maximum signal power threshold, provide for control of a respective gain of one or both of the first amplifier and the second amplifier.
