RF RECEIVER FOR MULTI-BAND

摘要

In a multi-band RF receiver according to the desirable embodiment of the present invention, costs are reduced by sharing a part of components required in the multi-band receiver between bands and the size of the RF receiver is reduced. Also, according to the present invention, yield is improved by a small chip size if the entire or part of the RF receiver is implemented in one semiconductor chip. The multi-band RF receiver according to the desirable embodiment of the present invention includes: first and second low noise amplifiers which amplify RF signals of a first band and a second band; first and second mixers which down-convert the signals outputted from the first and second low noise amplifiers by using first and second local oscillators and output the converted signals as intermediate frequency signals; and a first harmonic remover which removes harmonic elements from the output signals of the first and second mixers.
