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: A radio frequency (RF) receive circuit is described herein. In accordance with one embodiment, the RF receive circuit includes a mixer configured to receive an RF input signal to down-convert the RF input signal into a base-band or intermediate frequency (IF) band, an analog-to-digital converter (ADC), and a signal processing chain coupled between the mixer and the ADC. The signal processing chain includes at least two circuit nodes. The RF receive circuit further includes an oscillator circuit that is configured to generate a test signal. The oscillator circuit is coupled to the signal processing chain and is configured to selectively feed the oscillator signal into one of the at least two circuit nodes.

Abstract: An integrated circuit is described herein. According to one or more embodiments, the integrated circuit includes a local oscillator with a voltage-controlled oscillator (VCO) that generates a local oscillator signal. Further, the integrated circuit includes a frequency divider coupled to the VCO downstream thereof. The frequency divider provides a frequency-divided local oscillator signal by reducing the frequency of the local oscillator signal by a constant factor. A first test pad of the integrated circuit is configured to receive a reference oscillator signal. Further, the integrated circuit includes a first mixer that receives the reference oscillator signal and the frequency-divided local oscillator signal to down-convert the frequency-divided local oscillator signal.
