Wireless circuitry can have an antenna coupled to a receiving amplifier. The receiving amplifier may be coupled to a local feedback loop configured to reduce the gain of the receiving amplifier for suppressing the signal power when receiving a large input signal. The local feedback loop can include a detector and a feedback controller. The detector may have an input coupled to the receiving amplifier and can output a detected signal. The feedback controller may receive the detected signal and output a corresponding control signal. The control signal can be used to reduce the gain of the receiving amplifier by adjusting one or more components within or coupled to the receiving amplifier. Suppressing large input signals in this way presents no additional parasitic loading to the downlink path and can thus provide overvoltage protection without degrading receiver performance.
