Abstract
In an example, a receiver protection circuit includes a directional coupler configured to be coupled to a receive signal path of a communications device between an isolation device and an amplifier of the receive signal path. The receiver protection circuit further includes a power detector coupled to the directional coupler and configured to measure a power level of a transmit leakage signal in the receive signal path. The receiver protection circuit further includes a comparator configured to compare the measured power level of the transmit leakage signal in the receive signal path to a threshold value and output an alarm signal indicating that the measured power level of the transmit leakage signal exceeds the threshold value.
