Patent ID: 11233495

Abstract:
A mixer includes: a VGA (12) configured to amplify one of divided two portions of an input signal at a gain of cos θ; a VGA (13) configured to amplify another one of the divided two portions of the input signal at a gain of sin θ; an IQ generator (15) configured to input an LO wave, and output an LO wave in phase with the input LO wave and an LO wave having a phase difference of 90° with respect to the input LO wave; a mixer (16) configured to input the signal output from the VGA (12) and the LO wave which is output from the IQ generator (15), to output an RF signal; a second mixer (17) configured to input the signal from the VGA (13) and the LO wave which is output from the IQ generator, to output an RF signal; and a combiner (18).
