摘要： A broadband receiver is provided to convert a high frequency receiving signal to receive in a mixer into a baseband signal of a high DC(Direct Current) level and suppress the signal of harmonic components to convert into the signal of a low DC level, thereby extracting a baseband signal smoothly clearly. A high frequency front end unit(110) receives a broadband signal. A local oscillator generates a local oscillation signal. An oversampling delta sigma modulator(140) performs the oversampling and delta sigma modulation of the local oscillation signal, and converts the local oscillation signal into a digital signal. A mixer(120,122) mixes the output signal of the high frequency front end unit and the output signal of the oversampling delta sigma modulator to convert a high frequency receiving signal to receive into a baseband signal. A baseband signal processor(160,162) processes the baseband signal converted by the mixer.

摘要： A broadband receiver is provided to extract noiseless, clean Rx data by suppressing harmonic components in the case of converting received RF signals into baseband signals in a direct conversion method. A broadband receiver is comprised of an RF front-end part(110), a multi-phase controller(120), and a baseband signal conversion part(130). The RF front-end part receives an RF signal associated with a channel control signal. The multi-phase controller has a frequency associated with the channel control signal, and creates a plurality of square-wave phase signals and sine-wave phase signals which have different phases at mutually identical intervals. The baseband signal conversion part mixes the received RF signal with the created square-wave phase signals and sine-wave phase signals so that harmonic components can be mutually cancelled, and converts the received RF signal into a baseband signal.
