Abstract: A radio frequency (RF) circuit includes a signal path coupled between two RF inputs and at least one baseband output terminal. The signal path includes a 90° hybrid coupler including a first port that receives a first RF signal and a second port that receives a second RF signal. The 90° hybrid coupler generates a first coupler output signal based on the first RF signal and the second RF signal and generates a second coupler output signal based on the first RF signal and the second RF signal. The signal path includes a quadrature down-converter configured to down-convert the first coupler output signal into a first baseband signal and down-convert the second coupler output signal into a second baseband signal. The RF circuit includes a baseband combiner circuit configured to combine the first baseband signal and the second baseband signal to generate at least one of output signal.

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.

Abstract: A method for the use in a radar system is described herein. In accordance with one embodiment, the method includes providing a local oscillator signal to an RF output channel of a radar system. The RF output channel is configured to generate, in an enabled state, an RF output signal based on the local oscillator signal. The method further includes determining a first measurement signal based on the local oscillator signal and a first representation of the RF output signal, while the RF output channel is disabled, and thus the first measurement signal represents crosstalk. Further, the method includes determining a second measurement signal based on the local oscillator signal and a second representation of the RF output signal while the RF output channel is enabled. A phase value associated with the RF output channel is determined based on the first measurement signal and the second measurement signal.
