ABSTRACT:
A transceiver includes a detuning circuit to generate an impedance mismatch in a receive signal path in response to a control signal provided by loop-control circuitry. The loop-control circuitry generates the control signal based on a comparison of detected peak signal levels in the receive signal path. In this way, high-power input signal levels in the receive signal path may be reflected back to an input of the receiver due to the impedance mismatch.
