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.

Abstract: The present disclosure relates to a concept for calibrating an IQ modulator. A calibration method comprises setting one or more control values of the IQ modulator corresponding to a desired constellation point of a constellation diagram to generate an IQ modulating signal; mixing the IQ modulating signal with a carrier signal to generate an IQ modulated transmit signal; transmitting the IQ modulated transmit signal towards a predefined object at a predefined location; receiving a reflection of the IQ modulated transmit signal from the predefined object; mixing the received reflection of the IQ modulated transmit signal with the carrier signal to generate a down-converted receive signal; comparing amplitude and/or phase of the down-converted receive signal with the desired constellation point of the constellation diagram; and adjusting the one or more control values of the IQ modulator until a deviation between the amplitude and/or phase of the received down-converted signal and the desired constellation point falls below a predefined threshold.

Abstract: The present disclosure relate to a receiver system that removes unwanted signal components from a received signal based upon signal information from previous received signals. The receiver system has a signal generator that generates multiple signal patterns. One of the multiple signal patterns is provided to a transmit antenna that wirelessly transmits the signal pattern. A receive antenna port receives a reflected signal comprising a time-shifted version of the signal pattern and provides the reflected signal to a reception path. A feedback path extends from the reception path to a signal correction element, which selectively generates a correction signal that reduces unwanted signal components in the reflected signal. The signal correction element generates the correction signal from compensation parameters stored in a memory, which correspond to previously received reflected signals comprising the signal pattern, so that the correction signal can be used to reduce unwanted signal components in real time.
