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: An on-chip power sensor and a millimeter-wave communication device (e.g. transmitter or transceiver) on a chip including the on-chip power sensor are described. The millimeter-wave communication device can also include a coupler disposed on a transmit path, the coupler being configured to receive a transmit signal and to provide the transmit signal to an antenna connection (e.g. pad). The on-chip power sensor can be configured to receive a coupled portion of the transmit signal from the coupler, and measure a transmit power of the transmit signal based on the coupled portion of the transmit signal.

Abstract: A method for the use in a radar system is described herein. In accordance with one implementation, the method includes providing a local oscillator signal to a transmit channel of a radar chip. The transmit channel generates an RF output signal based on the local oscillator signal. An internal RF test signal is generated by applying the local oscillator signal to the transmit channel. First and second phase values are determined for a first and a second value of an influence parameter of the radar chip based on internal measurements of the first and second phase values. Third and fourth phase values are determined for the first and second values of the influence parameter, respectively, based on the RF output signal. A calibration parameter is calculated based on the first, second, third, and fourth phase values and is used to estimate a phase of the RF output signal.
