Abstract

One exemplary embodiment of the present invention relates to a circuit that includes at least one RF signal path for an RF signal and at least one power sensor, which is coupled to the RF signal path and configured to generate a sensor signal representing the power of the RF signal during normal operation of the circuit. The circuit further includes a circuit node for receiving an RF test signal during calibration operation of the circuit. The circuit node is coupled to the at least one power sensor, so that the at least one power sensor receives the RF test signal additionally or alternatively to the RF signal and generates the sensor signal as representing the power of the RF test signal.
