Abstract
A transmission line phase shifter, a chip, and a radar sensor are provided. The transmission line phase shifter includes at least one transmission line phase-shifting unit. At a calibration stage, a preset number of transmission line phase-shifting units are configured to be in a state of a first phase or in a state of a second phase and configured to output an output RF signal, such that phase calibration information of each transmission line phase-shifting unit is determinable. At an operation stage, the phase adjusting circuit of the respective transmission line phase-shifting unit is configured to receive a corresponding phase shifting control signal and to adjust the respective transmission line phase-shifting unit, to enable the respective transmission line phase-shifting unit to shift a phase of an input RF signal by a calibrated first phase or a calibrated second phase.
