Abstract
Disclosed herein is a mixer. The mixer may include an MLO switching unit configured to include 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 an LO switching unit configured to include 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. Each of the pairs of LO switches is connected to the positive and negative intermediate frequency (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.
