摘要：
The present invention relates to improvement of even order distortion noise, DC offset, and non-linearity of mixer circuits. According to the present invention, a mixer circuit is provided, which comprises a splitter for splitting an input signal to the first and second signal having phase difference of 180 degree, a local oscillator, first mixer for mixing the first signal with the local oscillation signal, second mixer for mixing the second signal with the local oscillation signal, and subtractor for subtracting the output of the second mixer from the output of the first mixer.
