Patent ID: 8874064

Claim:
A receiver, comprising: a signal receiver configured to receive a first signal; a frequency generator configured to synchronize a phase of the received first signal, convert a frequency size of the synchronized first signal to a first size, and output the converted signal as a second signal; a first harmonic mixer unit configured to generate, based on the first signal and the second signal, a third signal having a frequency size converted to a second size, and output the third signal; a second harmonic mixer unit configured to output, based on the third signal, an In-phase signal by using a signal having a frequency size converted to a third size; and a third harmonic mixer unit configured to output, based on the third signal, a Quadrature-phase signal by using a signal having a frequency size converted to the third size, wherein the first harmonic mixer unit includes a multi-phase filter configured to output, based on the first signal, a plurality of phases, and a first harmonic mixer configured to generate, based on the plurality of phases from the multi-phase filter and the first signal, the third signal and output the third signal.
