Abstract
A phase-shifting circuit and a radio frequency microwave system are provided. The phase-shifting circuit includes a first node circuit, a second node circuit, and a first signal channel and a second signal channel coupled between the first node circuit and the second node circuit. The first node circuit is configured to split an input signal to simultaneously output a first differential signal to the first signal channel, and output a second differential signal to the second signal channel. The first signal channel and the second signal channel are implemented based on an architecture of a differential circuit, and configured to perform at least one of a signal attenuation and a quadrant transformation on the first differential signal and the second differential signal for phase-shifting. The second node circuit is configured to synthesize a first phase shift signal output by the first signal channel and a second phase shift signal output by the second signal channel to obtain an output signal, and a phase difference between the output signal and the input signal is within a range of 0 deg-360 deg.
