Abstract: An integrated circuit (IC) for use in a short-range communication reflector device, the IC comprising a processor, a tone generator and/or packet generator electrically coupled to the processor, and a power amplifier electrically coupled to both the processor and the tone generator and/or packet generator. The processor is configured to process an incoming tone signal, determine a tone quality indicator, TQI, of the incoming tone signal, wherein the processor is configured to instruct the power amplifier to modulate an amplitude of an outgoing tone signal based on the determined TQI. Similarly, for packets the processor is configured to process an incoming packet and determine a packet quality indicator, PQI, of the incoming packet, wherein the processor is configured to instruct the power amplifier to modulate an amplitude of an outgoing packet based on the determined PQI.

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: Wireless receivers and related methods with interferer immunity are disclosed. The receiver includes a receive (RX) front-end, a power level detector, and an automatic gain controller (AGC). The RX front-end includes circuit(s) having variable gains, and the power level detector outputs a power level indicator. The AGC receives the power level indicator and outputs the gain settings to the variable-gain circuits within the RX front-end. Further, the AGC is configured to adjust the gain settings within a first gain range when not receiving data frames and to adjust them within a second gain range when receiving data frames. The second gain range is a restricted version of the first gain range. Further, the AGC can be configured to detect and store gain settings within a sliding time window when data frames are not being received and to use these stored gain settings to determine the second gain range.
