Abstract
A harmonic-rejection mixer apparatus includes a mixing circuit and a combining circuit. The mixing circuit receives mixes an input signal and a first local oscillator (LO) signal to generate a first output signal, and mixes the same input signal and a second LO signal to generate a second output signal, wherein the first LO signal and the second LO signal have a same frequency but different phases. The combining circuit combines the first output signal and the second output signal, wherein harmonic rejection is at least achieved by combination of the first output signal and the second output signal.
