Abstract:
An RF front-end circuit of an RF transceiver is described herein. In accordance with one exemplary embodiment, the fronted circuit includes a local oscillator (LO) configured to generate an RF transmit signal, an RF output port coupled to the local oscillator, wherein the RF transmit signal is output at the RF output port, and a monitoring circuit receiving an input signal and configured to determine the phase of the input signal or the power of the input signal or both. A directional coupler is coupled to the RF output port and configured to direct a reflected signal incoming at the RF output port as input signal to the monitoring circuit, and a controller is configured to detect, based on the determined phase or power or both, a defect in a signal path operably connected to the RF output port.

Claim (Index 1):
A radar front-end circuit of a radar transceiver, the circuit comprising:\n a local oscillator (LO) configured to generate a radio frequency (RF) radar signal; a first transmit channel comprising a first RF output port coupled to the local oscillator; a first IQ modulator coupled to the local oscillator to receive the RF radar signal and configured to tune a phase of the RF radar signal to generate a first phase tuned RF radar signal; a first RF amplifier coupled to the first IQ modulator to receive the first phase tuned RF radar signal and configured to provide a first amplified RF radar signal as a first RF radar transmit signal; a first monitoring circuit configured to receive a first input signal and configured to determine at least one of a phase of the first input signal or a power of the first input signal; a first directional coupler coupled to the first RF output port and configured to direct a first reflected signal incoming at the first RF output port as the first input signal to the first monitoring circuit, wherein the first directional coupler is coupled between an output of the first RF amplifier and the first RF output port and is configured to direct the first amplified RF radar signal to the first RF output port; and a controller configured to detect, based on the at least one determined phase or determined power of the first input signal, a first defect in a first signal path operably connected to the first RF output port, wherein the controller is configured to tune a phase of the first RF radar transmit signal to match with a phase of a second RF radar transmit signal of a second transmit channel.
