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.
