Claim Text:
1. A mixer, comprising: a master local oscillator (MLO) switching unit configured to comprise at least three MLO switches provided in odd numbers and configured to branch a signal from an input stage and to receive respective MLO signals; and a local oscillator (LO) switching unit configured to comprise pairs of LO switches connected in parallel to output sides of the MLO switches, wherein each of the pairs of LO switches corresponds to each of the MLO switches and output sides of each of the pairs of LO switches are connected to respective positive and negative intermediate frequency (IF) output sides, wherein each of the pairs of LO switches is connected to the positive and negative IF output sides so that the output sides of each of the pairs of LO switches alternately apply output signals to the positive and negative IF output sides when LO signals are sequentially input to each of the pairs of LO switches, wherein a signal having a frequency of 2f wherein a signal having a frequency of f wherein “n” is the number of MLO switches, and wherein a flicker noise is up-converted into the frequency of f
