摘要： PROBLEM TO BE SOLVED: To provide a mixer which can concurrently reject a harmonic signal and an image signal at a mixer edge without using an external element, and a radio frequency (RF) receiver using the mixer.
SOLUTION: A mixer used in an RF receiver is provided. The mixer includes a first harmonic rejecter for rejecting a harmonic signal component from a first input signal; and a second harmonic rejecter for rejecting a harmonic signal component from a second input signal. The first harmonic rejecter and the second harmonic rejecter are connected in parallel to reject an image signal component from the first input signal and the second input signal. Thus, the RF receiver can reject the harmonic signal and the image signal without using an external element.

摘要： The present invention relates to a harmonic removing mixer device for removing harmonic components and an operation method thereof. Here, a harmonic removing mixer comprises: a local oscillator which generates a local oscillation (LO) signal; at least one frequency converter which multiplies said local oscillation signal by different variables, and provides the multiplied signals to at least two mixers; at least two mixers which convert a frequency band of an input signal by using the local oscillation signal that is provided from said local oscillator and said at least one frequency converter; at least one phase shifter which adjusts a phase of an output signal of at least one remaining mixer, except one of said at least two mixers; and a combiner which combines the output signal of said one mixer with an output signal of said at least one phase shifter.
