Abstract

The embodiment of the invention provides a multi-phase shifter and a multi-phase shifting method. The multi-phase shifter comprises an orthogonal signal generator, a differential adder, a controller and an amplifying circuit, the output end of the orthogonal signal generator is connected with the first input end of the differential adder, and the orthogonal signal generator is used for generating an orthogonal signal; the output end of the controller is connected with the second input end of the differential adder and the first input end of the amplification circuit, and the controller is used for generating a first control signal and a second control signal based on a preset phase shift angle; the output end of the differential adder is connected with the second input end of the amplifying circuit, and the differential adder is used for performing vector synthesis on an orthogonal signal based on the first control signal to obtain a first in-phase orthogonal signal; and the amplification circuit is used for performing power amplification and phase compensation on the first in-phase orthogonal signal based on the second control signal to obtain a second in-phase orthogonal signal.

Description

technical field [0001] The present application relates to phase shifter technology, in particular to a multiphase phase shifter and a multiphase phase shift method. Background technique [0002] In the related art, since the differential adder in the phase shifter has different gains for different phases, it is necessary to control the gain of the amplifier when the power amplification circuit of the post-stage amplifier of the differential adder performs power amplification. The insertion phase of the amplifying circuit changes with the change of the gain under different gains, so it will significantly affect the phase shifting accuracy. Contents of the invention [0003] Embodiments of the present application are expected to provide a multi-phase phase shifter and a multi-phase phase shift method. [0004] In the first aspect, the embodiment of the present application provides a multiphase phase shifter, including: a quadrature signal generator, a differential adder, a ...
