Patent number: 11340330Abstract: 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.Type: GrantFiled: August 30, 2019Date of Patent: May 24, 2022Assignee: Infineon Technologies AGInventors: Jochen O. Schrattenecker, Lukas Heschl, Helmut Kollmann, Mathias Zinnoecker

Patent number: 11158944Abstract: 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.Type: GrantFiled: January 10, 2019Date of Patent: October 26, 2021Inventors: Jochen O. Schrattenecker, Niels Christoffers, Vincenzo Fiore, Bernhard Gstoettenbauer, Helmut Kollmann, Alexander Melzer, Alexander Onic, Rainer Stuhlberger, Mathias Zinnoecker
