  • Patent number: 11340330
    Abstract: A radar transmitter is described. The radar transmitter may include the following: a transmit channel which is designed to receive a local oscillator signal and to generate a high-frequency (HF) radar signal based on the local oscillator signal; a phase shifter contained in the transmit channel which is designed to set a phase of the HF radar signal depending on an input phase value; and a coupler contained in the transmit channel which is designed to receive the HF radar signal and output the HF radar signal at an output contact. A phase controller circuit is assigned to the transmit channel, where the circuit is coupled with the coupler and is designed to receive the local oscillator signal and the HF radar signal, and to adjust the input phase value for the phase shifter based on a phase difference between the local oscillator signal and the HF radar signal.

  • Publication number: 20210391650
    Abstract: A circuit includes a radio frequency (RF) channel including an input node and an output node and being configured to receive an RF oscillator signal at the input node and to provide an RF output signal at the output node; a mixer configured to mix an RF reference signal and an RF test signal representative of the RF output signal to generate a mixer output signal; an analog-to-digital converter configured to sample the mixer output signal in order to provide a sequence of sampled values; and a control circuit configured to provide a sequence of phase offsets by phase-shifting at least one of the RF test signal and the RF reference signal using one or more phase shifters, calculate a spectral value from the sequence of sampled values; and calculate estimated phase information indicating a phase of the RF output signal based on the spectral value.

  • Patent number: 11158944
    Abstract: A circuit is described herein. In accordance with one embodiment the circuit includes two or more RF channels, wherein each channel includes an input node, a phase shifter and an output node. Each channel is configured to receive an RF oscillator signal at the input node and to provide an RF output signal at the output node. The circuit further includes an RF combiner circuit that is coupled with the outputs of the RF channels and configured to generate a combined signal representing a combination of the RF output signals, and a monitor circuit that includes a mixer and is configured to receive and down-convert the combined signal using an RF reference signal. Thus a mixer output signal is generated that depends on the phases of the RF output signals.

  • Patent number: 11137489
    Abstract: A radar system includes a first chip having a first radio frequency (RF) contact; a second chip having a second RF contact; a first RF oscillator integrated in the first chip and has an output coupled to the first RF contact; a second RF oscillator integrated in the second chip; a transmission line connecting the first RF contact to the second RF contact; a demodulator that is arranged in the second chip and has a first RF input; wherein the first RF oscillator is configured to generate a first RF oscillator signal that is transmitted to the first RF input of the demodulator via the first RF contact, the transmission line, and the second RF contact, and wherein a controller is configured to determine a first propagation delay of the first RF oscillator signal arriving at the second chip on a basis of information obtained from the demodulator.
