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.

Abstract: A radio frequency (RF) inverter, a transmission line phase shifter, a system, a chip, and a radar sensor are provided. The RF inverter includes an inductance circuit and a first phase adjusting circuit that both are arranged symmetrically along a same symmetry axis. The inductance circuit includes a single-ended signal interface and a differential signal interface. The first phase adjusting circuit includes two controlled switches, and each controlled switch is connected between the ground wire and a corresponding ground terminal of a pair of ground terminals in the single-ended signal interface, to enable the inductance circuit to perform in-phase or inverting phase shifting on a received RF signal.

Abstract: The invention continuously deposits materials used to grow a thin film onto a moving tape. The invention preferably uses a pay-out reel and take-up reel to respectively dispense and spool the tape substrate at a constant rate. The invention preferably uses a series of stages to form the thin film on the tape, and includes at least one reactor or reaction chamber to deposit one or more materials onto the tape substrate that is used to form the superconductor layer, and one or more chambers to deposit buffer layers between the film and the metal tape substrate or between layers of film, as well as for the deposition of coating layers. The invention also preferably uses transition chambers between the stages to isolate each stage from the other stages.
