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.
