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.

Abstract: One example discloses a wireless device, comprising: an input configured to receive an interference signal; a transmitter configured to generate a transmit signal having either a first data rate or a second data rate; and a controller coupled to the input and the transmitter, and configured to define an interference threshold; wherein the controller is configured to command the transmitter to modulate the transmit signal at the first data rate if the interference signal is below the interference threshold, and modulate the transmit signal at the second data rate if the interference signal is above the interference threshold.
