The embodiment of the present application proposes a multi-phase phase shifter and a multi-phase phase shifting method. The multi-phase phase shifter includes: a quadrature signal generator, a differential adder, a controller and an amplifying circuit; the output ends of the controller are respectively connected to The input end of the quadrature signal generator and the first input end of the differential adder are connected, and the controller is used to generate the first control signal based on the frequency of the input radio frequency signal, and generate the second control signal based on the target phase shift angle; the quadrature signal generator The output end of the differential adder is connected to the second input end of the differential adder, and the quadrature signal generator is used to generate an orthogonal signal of a corresponding frequency based on the first control signal; the output end of the differential adder is connected to the input end of the amplifying circuit, and the differential adder is used The quadrature signal is vector-combined based on the second control signal to output the first in-phase quadrature signal; the amplifying circuit is used to amplify the power of the first in-phase quadrature signal to output the second in-phase quadrature signal.
Description
technical field [0001] The present application relates to phase shifter technology, and in particular, to a polyphase phase shifter and a polyphase phase shift method. Background technique [0002] In the related art, since the bandwidth of the quadrature signal generator in the phase shifter is not wide enough, the quadrature signal cannot be generated under the wide bandwidth, thus limiting the bandwidth of the entire phase shifter. SUMMARY OF THE INVENTION [0003] The embodiments of the present application are expected to provide a polyphase phase shifter and a polyphase phase shift method. [0004] In a first aspect, an embodiment of the present application provides a polyphase phase shifter, including: a quadrature signal generator, a differential adder, a controller, and an amplifier circuit; [0005] The output end of the controller is respectively connected with the first input end of the quadrature signal generator and the first input end of the differential add...
