MIXER AND RF RECEIVER USING THE MIXER

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. COPYRIGHT: (C)2011,JPO&INPIT
